Description of Self Test Items C-11
â—¼ 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.1.27 Z0703 PHV Board HV Test
â—¼ Top test item
MF FPGA and PHV ARM interconnection test
â—¼ Test content
Read positive and negative 100 V high-voltage value via PHV serial port drive.
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The positive and negative 100 V does not meet the requirement if the test result is FAIL.
â—¼ 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.1.28 Z0801 DSP FPGA and CPLD Interconnection Test
â—¼ Top test item
PC module and DSP FPGA interconnection test
â—¼ Test content
Test whether SPI interface communication between DSP FPGA on engine board and CPLD on
probe board works well
â—¼ 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.
â—¼ 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.1.29 Z0802 HALL Signal Test
â—¼ Top test item
Z0801 DSP FPGA and CPLD interconnection test
â—¼ Test content
Test whether the HALL signal connection from DCP FPGA on engine board to CPLD on probe
board works well.
â—¼ 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.
