Description of Self Test Items C-21
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
If the test appears FAIL, it shows the theoretic voltage values of PVPP and NVPP and the
collected voltage values. Decide which part of the power supply signal goes wrong.
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 4D&TEE board if the test result is FAIL.
C.1.45 Z1404 TEE Temperature Signal Test
â—¼ Top test item
Communication test between DSP FPGA and 4D&TEE board
â—¼ Test content
Read the value of TEE temperature signal. The collecting of the TEE temperature works well if the
value keeps stable.
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The interconnection of TEE temperature signal goes wrong if the test appears 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 4D&TEE board if the test result is FAIL.
C.1.46 Z1405 TEE Angel Signal Test
â—¼ Top test item
Communication test between DSP FPGA and 4D&TEE board
â—¼ Test content
Read the value of TEE temperature signal. The collecting of the TEE angel signal works well if the
value keeps stable.
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The interconnection of TEE angel signal goes wrong if the test appears 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 4D&TEE board if the test result is FAIL.
