Description of Self-diagnosis Test Items C-17
C.1.32 Z1105 AFE Digital Interface Test
Test Content
The super stratum test item：Z1003 BF and DSP Interconnection Test(Data Interface).
Let AFE enter test mode to transmit the data to FPGA of transmitter board, check if the AFE chip
works normally.
Analysis when test failed
If prompt “AFE digital interface test FAIL. AFE XXX Broken;”，there may be malfunction on AFE chip
on receiving board. Please check the AFE chip.
Suggestion when test failed
Replace the receiving board is recommended.
C.1.33 Z1106 Transmission and Reception Function Test
Test Content
The super stratum test item：Z1004 AFE Digital Interface Test.
The connectivity test of 128 channels between transmission and receiving: only one channel
transmitting 2V 1M PHV1 wave every time, analyze if the sampling wave is PHV1 wave and the
Signal-to-Noise with another channel.
Analysis when test failed
If prompt “Open circuit emit receive channel: XXX”，states the wave which is transmitted by XXX
channel is incorrect. If prompt “Short circuit emit receive channel: XXX”，states XXX channel
transmitting affect another channel.
Suggestion when test failed
1. If prompt “Open circuit emit receive channel: XXX”. Please replace the receiving board first to
see if the problem is solved, and then the transmission board.
2. if prompt “Short circuit receive channel: XXX”. Please replace the transmission board first to see
if the problem is solved, and then the receiving board.

Test
Test Content
The super stratum test item：Z1001 BF1 FPGA and DSP FPGA Interconnection Test.
Test the connectivity of SPI control BUS between probe board and receiving board ,output probe ID
and logic version.
Analysis when test failed
