Description of Self Test Items C-9
The positive and negative 100 V does not meet the requirement 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.
It is recommended to replace PHV power supply board if the test result is FAIL .
C.1.22 Z0701 DSP FPGA and CPLD Interconnection Test

Top test item
PC module and DSP FPGA interconnection test

Test content
Test whether SPI interface communication between DSP FPGA on engine board and CPLD on
probe board works well

Analysis to test failure
The drive goes wrong if the test result appears
Error
.
Interconnection between DSP FPGA and CPLD 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.
It is recommended to change probe board if the test result is FAIL .
C.1.23 Z0702 HALL Signal Test

Top test item
Z0801 DSP FPGA and CPLD interconnection test

Test content
Test whether the HALL signal connection from DCP FPGA on engine board to CPLD on probe
board works well.

Analysis to test failure
The drive goes wrong if the test result appears
Error
.
The HALL signal connection from CPLD to DSP FPGA 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.
If the test result is FAIL, replace the probe board first, and then the engine board.
C.1.24
Z0801
Control Panel USB Interconnection Test

Top test item
N/A

Test content
Test USB communication between control panel and main unit works well via reading internal
USB disk drive.

Analysis to test failure
The drive goes wrong if the test result appears Error .
The communication between control panel and main unit goes wrong if the test result is FAIL .
