C-16 Description of Self-diagnosis Test Items
The connectivity test of control BUS between BF1 FPGA and BF1 FPGA of receiving board. If the
test is passed, logic version and compiling version of BF2 FPGA will be output.
Analysis when test failed
If prompt “BF1 FPGA and BF2 FPGA Interconnection Test(Control Interface) test FAIL;”，there may
be connectivity malfunction between BF1 FPGA and BF1 FPGA of receiving board, please check
the control bus before two FPGA.
Suggestion when test failed
Replace receiving board is recommended.
C.1.30 Z1103 BF and DSP Interconnection Test (Data Interface)
Test Content
The super stratum test item：Z1002 BF1 FPGA and BF2 FPGA Interconnection Test
The connectivity test of data BUS between FPGA of DSP board and BF2 FPGA of receiving board,
also BF1 FPGA and BF2 FPGA.
Analysis when test failed
If prompt “BF and DSP Interconnection Test(Data Interface) test PASS.”, there may be connectivity
malfunction of data BUS between FPGA of DSP board and BF1 FPGA of receiving board. Or BF1
FPGA and BF2 FPGA . please check the DSP board, receiving board and communication mother
board.
Suggestion when test failed
Replace the receiving board first to see if the problem is solved, then think about changing DSP
board.
C.1.31 Z1104 ATGC Function Test
Test Content
The super stratum test item：Z1003 BF and DSP Interconnection Test(Data Interface).
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 “ATGC function test FAIL.”，there may be malfunction on gain adjustment circuit of
receiving board
Suggestion when test failed
Replace the receiving board is recommended.
