Hello, I am working with a instrument where we frequently get the problem of frequency drop out, i.e. suddenly frequency signal goes missing i.e. goes to zero, this cause the loss in data as shown in the below image. Yellow is received frequency signal from Photodetector and Purple is the demodulated data (our desire output). When frequency goes zero the purple line is constant so data is lost.
Can you help me find a solution for this problem!
this can be few causes of this issue, interference from Photodetectors, Electrical noise or grounding issues, Instrument hardware or firmware glitches
Improve Signal-to-Noise Ratio
Shield cables, use noise filters, optimize Photodetector.
if it persist, i guess you just try another device
