Troubleshooting Guide

1. Introduction

The information in this document applies to SONOLINE Versa Plus systems with software version1.6.0 and higher.

2. Troubleshooting Strategies

This document contains the following troubleshooting sections:

Following are a few more hints that may help you use this document:

If you have no ideawhere the fault could be, you may first view the System Configuration andSystem Status menus (section 5.4, Diagnostic Menus: Detailed Description).Then you may open the rear panel and check the power supply voltages (section 7, Power SupplyVoltages and Fuses).Then you may try the troubleshooting test patterns (section 4.3, B/W Test Patterns... section 4.5,Colour Flow Test Patterns).Finally you may try the "Minimum Configuration" Installation method (section 9).

If you suppose the error is on one of the Doppler boards, try the Doppler test patterns (section4.4, Doppler Test Patterns).

If you suppose the error is on the A61 Coordinator-2 or on the A58 Translator-2, try the B/W testpatterns (section 4.3, B/W Test Patterns).

If you suppose the error is on one or just a few particular board(s), check the LEDs and testpoints on the questionable board(s) (section 8, LEDs and Test Points).

If the system displays an error code, look at section 6, Error Codesfor details.

If you want to check the monitor displayor test a video printer, use the test patterns describedin section 3, Preset Menu 5 Test Patterns.

If you need to test a system and have no transducer, look at section 4.6, Transducer Simulation.

If you want to test a single board or another "FRU"(Field Replaceable Unit) like the powersupply or a VCR, refer to the document SONOLINE Versa Plus System Tests,U4.LH500.094.01.01.02 (or newer).

The "bulb" symbol is used in a few places to indicate a troubleshooting hint.

3. Preset Menu 5 Test Patterns

Three test patterns are invoked from the preset menu 5, without the need for a password. They canbe used to check the monitor display, and to verify that the monitor display is printed correctly on avideo printer. These test patterns are also described in the Operating Instructions.

To recover from the test patterns:Press the Escor the Escapekey. (In some cases it is also possible to use the command CLS.)

If TGRAY has been used to enhance the contrast setting (see section 4.8, Special Functions), theGray Bar and Colour Bar test patterns may look different.

staircases.The upper staircase is (from left): black, red, yellow,green, light blue, dark blue, white, purple.The lower staircase is in the opposite direction.

Notes:

The two rightmost steps (top: purple, bottom: black)are somewhat shorter than the other steps.

The steps are not exactly aligned vertically.

A thin white vertical line at the left edge of the left

purple step, as well as a thin horizontal line betweenthe two staircases are both acceptable.

4. Troubleshooting Commands

A number of troubleshooting commands allows you, from the alphanumeric keyboard of theSONOLINE Versa Plus system, to ...

invoke test patterns

simulate transducers

read out system memory

calibrate the system front end, etc.

4.1 Troubleshooting Mode

To enter troubleshooting mode:Simply type the troubleshooting password SI5XX and press Enter, as after any command.

You may enter the troubleshooting password any time the system is in imaging mode (B,

M, BM, ...) or in Freeze mode. You cannot enter the troubleshooting password while apreset menu or a report is displayed, or when the system is in text input mode (F12), etc.

The password does not display on the screen, but a small, blinking horizontal command linecursor appears in the lower left corner of the image area.You can now enter the troubleshooting commands, which are explained in detail in sections4.3 ... 4.8.

While the system is in troubleshooting mode, it can be operated normally. Only the small,blinking horizontal command line cursor indicates that the system is in troubleshooting mode.

Keep in mind that the system remains in troubleshooting mode even after you used com-mands like Escape, CLS, TEST$OFF, FFTA$OFF, CFTEST0to recover from test patterns.Whenever you see the small, blinking command line cursor, the system is in troubleshootingmode!

4.2 Troubleshooting Passwords

The troubleshooting password SI5XX (see section 4.1) and the service menu password SERVICE(see section 5.1) should only be made known to trained technicians, and should be kept confiden-tial.

Because accidental use of certain troubleshooting commands may upset the system, make surethat you

do not leave the system unattended while troubleshooting mode or the service menu is on,

always reset the system when your work is done.

To recover from troubleshooting mode:Press the reset button on the LCD. This will initialize the system.

4.3 B/W Test Patterns

The B/W test patterns display data that is generated at various points in the A42 Effector (last boardin the analog front end) and A61 Coordinator-2 (first board in the digital back end).

The first two patterns, CHKAD1 and CHKAD2, can be used to determine if a fault is located in the

front end or in the back end.

If both test patterns are correct:

the digital back end is working correctly, so the error is in the analog front end.

If one or both of the test patterns are incorrect:

the error is in the digital back end(or in the test signal generator on the A42 Effector ...).

CHKAD1 Injects a DC level of approximately2.7 volts at the output of theA42 Effector board (at the very end

of the analog front end).

Displays a uniformly grey rectangle,together with a uniform A-mode display:

When the Dynamic Rangecontrol isrotated counter-clockwise, ... the dynamic range display gradually

changes from 66 to 35 dB, the rectangle becomes brighter, the A-mode display becomes wider.

CHKAD2 Injects a test signal at the output ofthe A42 Effector board (at the veryend of the analog front end).

Displays a rectangle with a grey bar,together with a ramp-shape A-mode dis-play:

When the Dynamic Rangecontrol isrotated counter-clockwise, ... the dynamic range display gradually

changes from 66 to 35 dB, the bright parts of the grey scale

become brighter and finally white, the slope of the A-mode ramp

becomes steeper.

With software version 1.6.0, the displaydepends also on the DGC and B gain set-tings.

Notes:

To recover from the CHKAD1 and CHKAD2 test patterns: press the reset button on the LCD toinitialize the system.

From CHKAD1 and CHKAD2 it is possible to invoke TSTRIPE, TEST3$ON, and TEST4$ON.

If the two test patterns do not look as shown: make sure to turn off TEST3$ON or TEST4$ON by

entering TEST$OFF.


11/56



56

The other three patterns TSTRIPE, TEST3$ON and TEST4$ON are injected at various points in theA61 Coordinator-2. Therefore they effectively test only the A61 Coordinator-2 and the A58 Transla-tor-2.

The two test patterns TEST3$ON and TEST4$ON can only be invoked when a transducer isselected. If there is no transducer available, use a "simulated" transducer (see section 4.6, Trans-ducer Simulation).


TSTRIPE Tests the frame memory output of

Note:

To recover from the TSTRIPE test pattern, there are three ways: pressEscon the alphanumeric keyboard,

press the Escapekey on the control panel(German: Zurck; French:Retour; Spanish: Salida), or

enter the troubleshooting command CLS.

In either case the system remains in troubleshooting mode.

4.4 Doppler Test Patterns

The two Doppler test patterns test the Doppler boards:

Before you invoke the Doppler test patterns, perform the following steps:

Select a transducer.If there is no transducer available: simulate a transducer (see section 4.6, Transducer Simulation).

Press the Dcontrol twice to activate Doppler mode.

Switch on Full Doppler mode (on LCD page D2).

Activate the MIN and MAX traces (on LCD page D1).

If FFTA$ON produces a correct test pattern and audio signal:

the complete Doppler module is operating correctly.

If FFTA$ON fails and FFTB$ON is correct :

the error is probably on the A49 Demodulator (or maybe on the A55 Synthesizer, but cer-

tainly not on the A56 Streamer-2).

FFTA$ON Tests all three Doppler boardsby injecting a test signal at thebeginning of the Doppler module.

A continuous, horizontal Doppler signalline and the MIN and MAX traces are dis-played, and an audio signal (continuoustone) is audible:

For all PRFs (Scaleor PRFkey) the signal line is at -PRF/2.

If you cannot see the signal line, it is probably cut off by the wall filter.In this case, decrease the cutoff frequency with the Filterkey.

If FFTA$ON was entered last and the audio signal of FFTA$ON is audible butthe previous FFTB$ON test pattern is still displayed, enter FFTB$OFF.

By varying the Doppler controls (D gain, Scale/PRF, audio gain, etc.), part ofthe Doppler data path (up to the loudspeakers) can be checked with theFFTA$ON Doppler test pattern.

FFTB$ON Tests the FFT function of the digitalsignal processor (DSP B) on theA55 Synthesizer.

A wideband Doppler signal and the MINand MAX traces are displayed:

Because this test pattern is injected after the wall filter, changing the cutofffrequency with the Filterkey has no effect.

All other Doppler controls on the front panel have no effect either (except forthe D gain control which controls the white noise from the speakers).

The white noise which you may hear is not part of the test signal, but is simplythe system noise: it does not change if the test signal is terminated withFFTB$OFF.

If FFTB$ON was entered last and the test pattern of FFTB$ON is displayedbut the previous FFTA$ON audio signal is still audible, enter FFTA$OFF.

Note:

To recover from the Doppler test patterns: enter FFTA$OFFor FFTB$OFF, respectively.

4.5 Colour Flow Test Patterns

A number of colour flow test patterns is available. The test pattern data is inserted at various pointsin the colour flow module:

CFTEST1 and CFTEST2 are analogtest signals, CFTEST3 ... COLORPAT are digitaltest data.

Hints for troubleshooting with the colour flow test patterns:

CFTEST1 and CFTEST2 are inserted at the very beginning of the colour flow module.Therefore, if CFTEST1 and CFTEST2 produce correct test patterns, it can be assumed that thecomplete colour flow module is operating correctly.

If one test pattern fails, but the next pattern down the chain is correct, the error must be in thehardware between the two insertion points. (This does not strictly apply for CFTEST9 andCOLORPAT, which are generated outside the colour flow module.)

If one test pattern fails, but the next one is correct:

The signals and data for CFTEST1 ... CFTEST4 are generated on the A50 Discriminator-2 itself,the first board of the chain.

If CFTEST1 ... CFTEST4 fail and CFTEST5 is correct, the error must be on theA50 Discriminator-2.

The data for CFTEST5 is generated on the A63 Correlator-2 itself.

If CFTEST5 fails and CFTEST9 is correct, the error must be on the A63 Correlator-2.

The data for CFTEST9 is generated on the A69 Administrator.

If CFTEST9 fails and COLORPAT is correct, the error is probably on the A53 Triplexer-2;but it may also be on the output of the A63 Correlator-2, or on the A69 Administrator.

The data for COLORPAT is also generated on the A69 Administrator.

If COLORPAT fails, the error is probably on the A54 Reflector;but it may also be on the A53 Triplexer-2, or on the A69 Administrator.

56

In short: If you want to test a single board in the chain, do the following:

To check the Interpolation function (located on the A54 Reflector), you must use CFTEST1 orCFTEST2, because COLORPAT requires that the system be in Freeze mode.

CFTEST1 and CFTEST2 use a small analog signal that is generated in the control ASIC on theA50 Discriminator-2.As this is a low amplitude analog signal, CFTEST1 and CFTEST2 can be used to approximatelycheck the colour flow gain of the A50 Discriminator-2.The analog test signal should be at a frequency of exactly PRF/2, and this frequency should be

detected correctly with exactly the same reference frequency. To verify that the A50 Discriminator-2 is correctly detecting the analog Doppler signal, you may perform the "green tag test" describedon page 17.

If you obtain test patterns that are somewhat different from those described on the followingpages, wait until the system has warmed up for at least 15 minutes. If necessary, close the systemcovers.

Refer to the Operating Instructions for more information on Colour Flow Imaging.

Before you invoke the colour flow test patterns, you must perform the following steps inorder to obtain correct results:

Enter the troubleshooting password.

Select any array transducer. Because the colour flow test patterns do not work with all simulatedtransducers, we recommend to use a real transducer connected to the system.

Select B-mode, and set B gain and all DGCslide pots to maximum: the image shape is visible.

Rotate the Depthcontrol clockwise and maximize the depth.

Press the Ccontrol: The green border of the ROI (region of interest) appears.

Rotate the Ccontrol clockwise and set the C gain to maximum: colour noise (red and blue

speckles) appears randomly in the ROI.

SetWindowto Pos, and move the ROI with the trackball into the upper left corner of theimage.

SetWindowto Size, and maximize the ROI with the trackball towards the lower right corner ofthe image: the near field continues to show the B/W reflections (depending on the B gain setting),while the middle and far field is filled with moving colour noise.

Set the colour flow parameters on the three LCD menu pages exactly as shown (menu page 3 isavailable only while the system is in troubleshooting mode):

Note: Parameters in bolded italicsare used later in certain tests.

Set Bgain and all DGCslide pots to minimum: the reflections in the near field disappear.

Set C gain to minimum.

Make sure that the system is using the downshifted Doppler frequency:the frequency that is highlighted behind the transducer code must be lower than the transducersnominal frequency. If the system is using the nominal transducer frequency, press the FrequencySelectkey to select (highlight) the downshifted frequency:

Make sure that the baseline is centered: the colour bar is symmetrical, and the values above andbelow the colour bar are equal. If necessary, bring the baseline to the center with the Baselinekey.

Make sure that Invertis off: the upper half of the colour bar is yellow ... red, the lower half is blue.

Note that the shape of the colour test patterns depends on the selected transducer.

Testing the A50 Discriminator-2 board: Green Tag Test

To verify that the A50 Discriminator-2 is correctly detecting the analog Doppler signal, you may per-

form the "Green Tag Test":

Invoke CFTEST3 or CFTEST4.

On LCD menu page 2, set Vel Tag to "Pnt". A "green tag" line appears in the colour bar.

Use the trackball to move, in the colour bar, the green tag line to exactly the middle of the orange(CFTEST3) or blue (CFTEST4) part of the colour bar.

When the green tag is exactly centered, the colour inside the ROI changes to a bright green. A feworange (or blue) speckles are acceptable. When the green tag is moved slightly up or down, thecolour inside the ROI changes back to orange or blue, respectively.This test verifies that the test data is at a frequency of exactly PRF/4, and that theA50 Discriminator-2 detects this frequency with exactly the same reference frequency.

Reset Vel Tagto "Off".


CFTEST1CFTEST2

The controller ASIC onthe A50 Discriminator-2injects an analog signal at

a frequency of PRF/2 intothe input of the colour flowsignal path.

The ROI is filled with blue (CFTEST1) or orange(CFTEST2).

The colour is only in the near field, and disappears

towards greater depths. With increasing C gain the colour disappears.

With software version 1.6.0, the colour extends to the

full depth of the image.

CFTEST3CFTEST4

The controller ASIC onthe A50 Discriminator-2generates a digital testpattern at the output ofthe A50 Discriminator-2.

The ROI is filled with orange (CFTEST3) or blue(CFTEST4).

The colour is uniform within the ROI.

CFTEST3 and CFTEST4 do not change if the Cgain is reduced.

With software version 1.6.0, CFTEST3/4 do not work.Notes:

For CFTEST1 ... CFTEST4, the system must notbe in Freeze mode.

With high B gain and DGC settings, there may be B/W reflections in the near field.

To recover from the CFTEST1 ... CFTEST4 test patterns: enter CFTEST0.

CFTEST5 Writes a digital test pat-tern into the buffer mem-ory at the input of the A63Correlator-2.

The image changes slowly, and after some secondsends up in a complicated test image, where thecoloured areas overlay the gray B image in the back-ground:

If Temporal(LCD menu C2) is increased, the num-

ber of vertical stripes decreases.

If Density(LCD menu C2) is increased, the num-ber of vertical stripes decreases.

If the Filterrocker switch is pressed. the shape of thevertical stripes changes.

If the Low Flow, Med Flow andHi Flowset-tings are changed, the shape and number of stripeschanges.

CFTEST9 Writes a digital test pat-tern into the persistence

memory at the output ofthe A63 Correlator-2.

The ROI is filled with coloured bands. Each bandchanges colour (from top to bottom) from red ... yel-

low ... light blue ... dark blue:

Notes:

For CFTEST5 and CFTEST9, the system must notbe in Freeze mode.

With high B gain and DGC settings, there may be B/W reflections in the near field.

To recover from the CFTEST5 and CFTEST9 test patterns: enterCFTEST0 (or reset thesystem).

4.6 Transducer Simulation

This feature allows partial testing of the system, even if there is no transducer connected to the sys-tem: As shown in sections 4.3 and 4.4, some test patterns can be invoked using the transducer sim-ulation feature.

For xxx, type one of the following 3-digit "probe IDs" (see next page):

Command Function Use and results!PROBE Enables/disables transducer simu-

lation (toggle function). First use of !PROBE enables

transducer simulation: This makesthe system ready for transducerselection via the LC and CWcommands described below.

You can now already invoke thetransducer list (on the LCD) bypressing the Transducerkey.The list may show a default selectionof some transducers.

Second use of !PROBE disablestransducer simulation.

CWD$ON Enables the CW=xxx command(see below)

Before the CW=xxx command (seebottom of this table) becomesfunctional, the CWD$ON commandmust be entered.

LC1=xxxorLC2=xxx(xxx: see below)

Select an array transducer on port1 or 2

After entering one of thesecommands, press the Transducerkey to invoke the transducer list onthe LCD, or press Transducertwice

to refresh the list (if alreadydisplayed).

The selected transducer appears(among others) in the transducer list.

Select one of the transducers on theLCD.

The transducer name and its imageshape display on the monitor.

CW=xxx(xxx: see below)

Select a CW Doppler transducer


21/56



56

Notes:

In the column "displayed name", the upper name is displayed on the LCD, and the lower name(xxxx) is displayed on the monitor screen.

Make sure not to forget the "1" or "2" in the LC command.

Leading zeroes in the probe ID must be typed: "009", not "9".

Make sure to enter the CWD$ON command before using the CW=xxx command.

If you do not need a particular simulated transducer, you may select one from the defaulttransducer list after entering the !PROBE command, without using the LC command.

To see the image shape of the simulated transducer: enter the TEST4$ON command.

To select a "real" transducer that is connected to the system:enter!PROBE a second time to disable transducer simulation, then press Transducer.The LCD now displays only the transducers that are connected to the system.

If you select a simulated transducer while a "real" transducer is connected to the system (even in adifferent port), you may get the image shape of the simulated transducer plusthe reflections (orpossibly a real time scan) from the "real" transducer.

5. Diagnostics

5.1 Introduction

In addition to the Troubleshooting Commands described in section 4, the SONOLINE Versa Plussystem provides diagnostic test software which allows you to collect information about the status ofthe system hardware.

Only authorized service personnel has access to the diagnostic test software through a special"service menu password" (see section 4.2, Troubleshooting Passwords).

There are three different types of diagnostics:

Start-Up DiagnosticsThese are automatically executed when the system is powered on (e.g. polling the boardrevisions).

Background Diagnostics

These are executed regularly while the system is operating (e.g. monitoring the power supplyvoltages), except while a preset menu is displayed.

Both the Start-Up and Background Diagnostics are normally "invisible" to the user.An error message is displayed only if the diagnostic software detects an error in the system.

Operator DiagnosticsThese are manually started from the keyboard.

In all three cases, the test results are written into the "Service Support Data Base" in the SONO-LINE Versa Plus system for later use (see next section).

In the initial customer release, not all planned features of the diagnostic software are available yet.


24/56



5.2 Service Support Data Base

The test results of the diagnostic software are stored in the Service Support Data Base, which islocated on the A69 Administrator.1

The following table shows which type of information is stored in the data base:

The upper halfof the table (except for the "Main Frame Serial Number") shows information which isupdated when the system is powered on, or periodically (in the background) while the system isworking.The lower halfof the table shows information which must not get lost when the system is switched

off, and which must not be overwritten.

The information in the Service Support Data Base can be viewed on the monitor by authorized ser-vice personnel (see section 5.3, User Interface, and section 5.4, Diagnostic Menus: Detailed Descrip-tion).

1. If the battery is removed from the board, the information in the Service Support Data Base is lost.If the board is replaced, the information in the Service Support Data Base is removed from the system.

5.3 User Interface

The user interface of the Diagnostic Software is the Preset Menu 5 and its sub-menus. Menu 5 isthe entry-point; and reading, writing, and clearing diagnostic test information is all done in sub-menus of menu 5.

To invoke menu 5 and its sub-menus:

Type the service menupassword SERVICE, and press the Enterkey.The password is not displayed on the monitor (except if in troubleshooting mode).

Press the function key F4 repeatedly until menu 5 is displayed:

Normally the last optionService Data in menu 5 is disabled (greyed out). To enablethis option, it is necessary to enter the service menu password first. If you find the optionService Data disabled, press Escape to leave menu 5, enter the service menupassword, and invoke menu 5 again.

Note that whenever you leave the "General System Set Up" (Menu 1 ... Menu 5), thesystem "forgets" that you had entered the service menu password! So make sure to enter

the service menu password always before you invoke menu 5.

Select the optionService Data with the trackball and the Setkey.Now menu 5.1 appears:

The information displayed in these sub-menus corresponds to the information shown in the table inchapter 5.2, Service Support Data Base.

Only the bolded options are available in the initial customer release.

8. LEDs and Test Points

8.1 Introduction

The boards of the SONOLINE Versa Plus imaging system contain LEDs and test points.

Please be aware that the LED and test point information shown on the following pages is valid forthe indicated board revisions. On newer board revisions the placement and meaning of the LEDsand test points may differ.

LEDs

In this document, only the three LED states "ON", "OFF" and "Flashing" are used. There is nodistinction made between LEDs driven by a constant voltage level, and LEDs that are driven by afast pulse sequence, unless the pulse frequency is so low that a "flashing" effect is visible.

The state of some LEDs may change- during power-up or reset- while switching from (the "standard") B-mode to M-, BM-, Doppler-, BD- or BMD-mode.The following pages usually describe only the "stable" LED states within a defined mode ofoperation.

Please be aware that the LED information shown on the following pages is just one of severaltroubleshooting tools. The behaviour of some LEDs can depend on a wide variety of systemsettings, so that the LED information may not be used as the only indicator to identify a defectiveboard.

Test Points

Only those test points which are relevant for the field service are shown. These test points are

usually located on the outer edge of the boards, and can be accessed without an extender board.

Most of the test points not described here are for debugging purposes at the manufacturer.

9. Minimum Configuration Installation

If somewhere in the system there is a fault which cannot be located immediately, the "MinimumConfiguration" Installation method may help you to find the faulty board:

Pull out all boards in the system from their connectors, except for

- boards that cannot be removed easily:A10 Operator, A21 Binder, A28 Isolator, and A35 Allocator, and

- a minimum configuration of boards that are needed to make the system respond (see Step 1below).

Add the other boards as described below, one by one, and check the system response.If the system does not respond as described, the board that was added last is probably the faultyboard.

Please keep in mind that the following list of checks cannot be complete, and there may be faultsthat may not be detected by this method.

The optional boards A66 Stabilizer (TEE transducer interface) and A67 Provider (optically isolated

RS-232C ports) are not covered in this chapter.

Turn power off before inserting or removing any board!

Boards in the system When board(s) are okay the system will respond as follows:

Step 1: Minimum Configuration

A62 Commander

A69 Administrator

after turning power on, all keys are illuminated for a short time

after the system has booted up, the LED of the B-mode control is

illuminated, and the LCD is active pressing any key produces the usual "click"

all B- and M-mode controls (e.g. B+B) respond correctly (i.e. theirlamps are illuminated)

upon pressing any LCD key, the annotation changes accordingly

Step 2: External video signal

add:

A58 Translator-2

after pressing the Video I/Okey, an external video signal (e.g. froma VCR) is displayed correctly


52/56



Step 3: Graphic Signal Display, Digital Test Patterns

add:

A61 Coordinator-2

after the system has booted up, the monitor displays:

CALIBRATION ERROR !! any black-and-white graphics can be displayed (for example

pictograms)

after pressing F4all 5 menus can be displayed

the Gray Bar Test Pattern and Grid Test Pattern (menu 5; seechapter 3, Preset Menu 5 Test Patterns) can be displayed

after entering the troubleshooting password, the digital testpatterns can be displayed: TSTRIPE, TEST3$ON, and TEST4$ON(see section 4.3, B/W Test Patterns)

Step 4: Calibration

add:

A42 Effector

while the system is booting the monitor displaysUnder Calibrationand then, temporarily,Uniformer Calibration Error

after entering the troubleshooting password and the commandCALIB, the messageCalibration Error is displayed.

if an array transducer is connected, and with Bgain turned fully on,the shape of the ultrasound image is visible against the background,and the DGCcontrols affect the displayed noise

the analog test patterns CHKAD1 and CHKAD2 can be displayed(ignore any error messages that might be displayed)

Step 5: Array Front End (Receive Beamformer)

add:

A45 Uniformer

A48 Alternator

one A46 Adjuster,

then test the system later:

the other A46 Adjuster(see text)

plug in A45, A48, and only one A46 Adjuster:with maximum B gain (and all DGC slide pots at maximum gain) theimage shows horizontal stripes (linear transducer) or concentricarcs (convex transducer)

install also the second A46 Adjuster and verify that the noise with

maximum gain is uniformly distributed without visible disruption

verify that the noise level changes when the Bgain control isrotated, and when the DGCslide pots are moved

Step 6: Complete Linear/Convex Array Signal Path (only black-and-white)

add:

A37 Launcher

A38 Initiator

after applying an array transducer on a phantom or on your bodyand optimizing all relevant parameters, a good ultrasound image isobtained



53/56



56

Step 7: Doppler

add:

A49 Demodulator

A55 Synthesizer

A56 Streamer-2

Doppler imaging is possible

after entering the troubleshooting password SI5XX, the test routinesFFTA$ON and FFTB$ON can be invoked. This tests the completeDoppler signal path, including audio.

the Max, Min, Mean, Mode Doppler traces can be activated and aredisplayed superimposed on the spectrum

with ECG option installed also the ECG trace can be activated anddisplayed on the monitor

Step 8: Colour Flow

add:

A50 Discriminator-2

A53 Triplexer-2

A54 Reflector

A63 Correlator-2

colour flow imaging is now possible: after optimizing all relevantparameters a good colour flow image is obtained

after entering the troubleshooting password SI5XX, the test patternsCFTEST1 ... CFTEST9 can be invoked

after freezing the image the test pattern COLORPAT can be invoked

Step 9: Complete Phased Array Signal Path (without scwD)

add:

A39 Steerer

A47a Expander

A47b Expander

with a phased array transducer, all modes and tests are possible

(without scwD)

Step 10: Complete Phased Array Signal Path (with scwD)

add:

A36 Harmonizer

with a phased array transducer, all modes and tests are possible(including scwD)

Step 11: CINE Mode

add:

A51 Scripter-2

scan for at least 60 seconds, press the Freezekey, press the CINEkey, and press Motion on the LCD: The CINE review (black-and-white or colour) is displayed continuously.

Step 12: Grabber

add:

A64 Grabber

colour images can be written to diskette and hard disk, and can bereloaded

in the retrieved images caliper measurements are possible. Thecalibration is done automatically.

10. Testing the HS Bus

10.1 Functional Overview of the HS Bus

The HS Bus connects the A62 Commander (bus master) with the A50 Discriminator-2, A61 Coordi-nator-2, A63 Correlator-2 and A55 Synthesizer.

The HS Bus transmits image control data for B, M, D and CFM modes, and receives board ID datafrom the A50 Discriminator-2 board.

The HS Bus is active only in the short time intervals between receive periods. This ensures that thesensitive analog electronics in the front end, while receiving ultrasound echo signals, is not affectedby noise from the digital HS Bus.

The following table shows the HS Bus signals:

The following diagram shows the coarse timing of the HS Bus signals:

with the following HS Bus activities:

10.2 Checking TXCL and the HS Bus Control Signals

If one or all of the boards mentioned in section 10.1 do not operate properly, the problem may becaused by a failure of TXCL, or by incorrect operation of the HS Bus.

TXCL is available as a LEDon the A62 Commander; TXCL and the HS Bus control signals areavailable as test pointson most of the connected boards:

The TXCL and HS Bus test points (notshown in section 8, LEDs and Test Points) are usuallylocated close to the lower mother board connector, so that an extender board is necessary.
