C-8 Description of Self Test Items

Analysis to test failure
The drive goes wrong if the test result appears
Error
.
The circuit of ATGC gain adjustment 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 replace engine board if the test result is FAIL .
C.1.19 Z0601 MF FPGA and PHV ARM Interconnection Test

Top test item
Communication self test between PC Module and MF FPGA

Test content
Test whether UART communication between DSP FPGA and PHV ARM works well. Send the
order through PHV serial port drive, and re-read the data via the port.

Analysis to test failure
The drive goes wrong if the test result appears Error .
UART interconnection between FPGA and PHV ARM goes wrong if the test fails.

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 PHV power supply board if the test result is FAIL .
C.1.20 Z0603 PHV Board PHV Mode Test

Top test item
MF FPGA and PHV ARM interconnection test

Test content
Adjust PHV voltage linearly, and set five voltage values. Read PHV1P, PHV1N, PHV2P and
PHV2N voltage values respectively via PHV serial port.

Analysis to test failure
The drive goes wrong if the test result appears Error .
The voltage value of PHV mode does not meet the requirement if the test result appears 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.1.21 Z0604 PHV Board HV Test

Top test item
MF FPGA and PHV ARM interconnection test

Test content
Read positive and negative 100 V high-voltage value via PHV serial port drive.

Analysis to test failure
The drive goes wrong if the test result appears Error .
