Description of Self-diagnosis Test Items C-19
C.1.38 Z1304 CW AFE Digital Interface Test
Test Content
The super stratum test item：Z1203 CW SPI Test.
Test the function of AFE on CW board: let AFE enter test mode , send test data to CW FPGA, read
the data to judge if it is correct or not.
Analysis when test failed
If prompt “CW AFE digital interface test FAIL. AFE XXX Broken;”，states that the XXX AFE chip of
CW board is failed, please check the AFE chip of CW board.
Suggestion when test failed
Replacing CW board is recommended.
C.1.39 Z1305 CW ATGC Function Test
Test Content
The super stratum test item：Z1204 CW AFE Digital Interface Test.
Increase ATGC gain, collect noise value of all channels to judge if the RMS value can increase
along with gain amplification.
Analysis when test failed
If prompt “CW ATGC function test FAIL.”，there may be malfunction on gain adjustment circuit of
CW board.
Suggestion when test failed
Replacing CW board is recommended.
C.1.40 Z1306 CW IQ Test
Test Content
The super stratum test item：Z1204 CW AFE Digital Interface Test.
Set the transmitting output frequency be different from the receiving frequency. Then I/Q will get a
fixed sine wave to judge if the function of I and Q route are normal.
Analysis when test failed
If prompt “I route Test FAIL;Q route Test FAIL.”, there may be malfunction on I and Q route circuit.
Suggestion when test failed
Replacing CW board is recommended.
C.1.41 Z1401 4D Driver Board ID Test
Test Content
The super stratum test item：Z0701 PC Module and DSP Interconnection Test.
