I’m struggling to implement the I/Q streaming feature of the 200c using the API. I have 2 sm200c’s using the same input, same trigger, same wiring and wire length, and same configuration. I’ve implemented some code that writes the buffer for each device to I/Q files for me to compare and I’m not getting the same outputs. The starting pulse time for each device is different from each other and from each previous run, but more importantly, the noise floors aren’t the same. Spike playback will show one around -50dBm (which I understand to be normal from other threads) and the other could be as high as -20 dBm. They take turns on which one is high and low, and occasionally, neither one is.
Is there a dynamic latency between triggering and recording? Why might my pulse times and widths be different from run to run? What may cause power fluctuations with each pulse? Why would playback show a signal with a noise floor way about another with the same configuration/conditions?
Thanks in advance!
