Hi,
I need an advice.
I need to measure rms/ppk of a 10G signal. The signal is an output of a TIA of a 10G PIN diode. The TIA output is a neg/pos pair. The output is connected through caps to a clock data recovery chip (a point-to-point connection).
My board material is rogers 4000 series. I was wondering if I could create a "coupler" by splitting the traces on the board, and be sure that the 10G signal is still intact.
I can allways take one TIA output and use that as an input to the detector, but then the CDR would get only the other pair.
