Description of Self Test Items C-13
C.1.26 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.1.27 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.
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 control panel if the test result is FAIL.
C.1.28 Control Panel Key, Encoder, TGC, Trackball
Function Test
Top test item
USB communication test of control panel
Test content
Test whether the control panel keys, encoders, TGCs, trackball, backlight LEDs and indicating
LEDs on the keyboard work well, and read board ID, keyboard FPGA version and program
version.
