Description of Self Test Items C-5
Test Content
Read +12V, +3.3V, +2.1V, +5V, +5.7V, -12 V, -5.7V, +2.9V, +5V_STB, +3.8V, +1.4V voltage values
on DC-Dc board via ADT7462 drive. Judge whether they match with the requirements.
Analysis to Test Failure
The drive goes wrong if the test result appears Error.
The voltage value does not meet the requirement if the test result appears FAIL.
Suggestion to Test Failure
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device if Error re-appears.
b) It is recommended to replace DC-DC board if the test result is FAIL.
C.1.11 Z0401 Primary LCD Monitor I2C Interconnection Test
Top test item
PC Module and MF FPGA Interconnection Test
Test content
Test whether I2C communication serial port between MF FPGA and primary LCD monitor works
well. The test generates primary LCD monitor’s saver, and then restores it. Primary LCD monitor’s
brightness decreases, and then returns back. Read the hardware and software versions of
primary LCD monitor.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The interconnection between DSP FPGA and primary LCD monitor goes wrong if the test result is
FAIL.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
Check whether the connecting material between primary LCD monitor and main unit is fixed well,
and then replace primary LCD monitor if the test result is FAIL.
C.1.12 Z0402 Primary LCD Monitor Serial Number Test
Top test item
Primary LCD Monitor I2C Interconnection Test
Test content
The test reads the serial number of the primary LCD monitor and compares the serial number with
that in the configuration file.
Analysis to test failure
If the test result is NaN, it indicates the primary LCD monitor does not support the test.
If the test result is FAIL, it indicates the serial number of the primary LCD monitor is not consistent
with that in the configuration file.
Suggestion to failure test
Deselect the test if the test result appears NaN.
Restart the ultrasound system if the test result is FAIL.
