Subject: why is the first channel output error?  

 Hi,

 The diagram below is DRS4 output. Green is the output8+, blue is the output8-. Output8+ of the first channel is below  the baseline. It is not  right.

Others channel  is suitable. I check the circuit , Hardware is no problem, so I want to konw where the FPGA code  is wrong. what reason is caused? Thanks!
