Test systems are service
test units for the ultrasonic diagnostic
equipment model SSA-340A.

No. 2D730-136E
If a malfunction occurs,
with respect to PWBs and PWB blocks,
responsible for the malfunction by displaying error codes.
the test system will indicate the test results
identifying those which are
Alternately,
the test system will indicate a pattern which permits assessment of the
quality of each block.
Tests principally involve the CPU unit, PANEL unit, RPG, DSC unit, T/R
unit, FFT unit, and CFM unit.
Although not all units are included, it is
possible to test the basic units required for generating an image.
Therefore,
troubleshooting is expedited if the test system succeeds in
helping identify faulty units.
Furthermore,
at the time of maintenance and checking it is possible to
assess changes in ultrasonic wave transmission which-are difficult to
observe during- the normal service period; degradation of system
performance;
and memory errors of any addresses caused by faulty
reception.
In addition,
there are guidelines for test performance frequency.
is useful for checking faults that occur infrequently, caused by RS-232C
communication errors.
2.1 Configuration of the Test System
This
This test system is incorporated in the main unit of the diagnostic
ultrasound system.
This manual describes the operating procedures for the test system.
2.2 Diagnostic Items and-Nature of Tests in the Test System
PWBs which are tested by the test system are shown in figure 2-1 to
figure 2-3.
Details concerning each test item are given in tables 2-1
and 2-2.

l Palm controller trackball
l Trackball (TRACK BALL FUNCTION)
(6) When the graphic check of the CPU is completed, either of the two
lines for time display may not be displayed; however, this is not

(7) Because peripheral devices may malfunction during testing,
disconnect the control cables of all peripheral devices during
testing. Alternatively,
turn OFF the power of all peripheral
devices.
(8) Be sure to execute New Patient after the test has been completed.
