Description of Self-test Test Items C-9
C.1.22 Z0303 TRB AFE Digital Interface Test
 Top test items
TRB AFE SPI Interface Test
 Test content
Enter system test mode, write the data to TRB AFE, input delay RAM, re-read the
data from delay-channel memory and make the judgment to locate the channel and
AFE clip.
 Analysis to test failure
The drive goes wrong if the test result appears Error.
AFE clip goes wrong if the test result is FAIL.
 Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) It is recommended to replace TR64 board if the test result is FAIL.
C.1.23 Z0304 DSP FPGA and TRA&TRB Interconnection
Test (Data Interface)
 Top test items
a) DSP FPGA and TRA Interconnection Test (Control Interface)
b) DSP FPGA and TRB Interconnection Test (Control Interface)
 Test content
Test whether XCVER data bus between TRB FPGA of TR64 board and TRA FPGA
works well. Test whether XCVER data bus between TRA FPGA on the main board
and DSP FPGA works well.
 Analysis to test failure
The drive goes wrong if the test result appears Error.
XCVER data bus on the connection of TRB FPGA-TRA FPGA-DSP FPGA goes
wrong if the test result is FAIL.
 Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b)
It is recommended to replace TR64 board if the test result is FAIL. If the error still
exists, it is recommended to replace CPU.
C.1.24 Z0305 TRB Transmission and Reception Function
Test
 Top test items
ATGC Function Test
 Test content
Test the coherence of 64 channels (from 1
st
channel to 64
th
channel) in transmitting
and receiving: one channel transmits 2V 1M PHV1 waveform each time, and
