I'm measuring the noise of my system using a Picoscope 5000 series and a silicon fast photodetector, however, when I process the data taken from Picoscope software I find there are single-point-spikes on my RIN vs frequency plot down to extremely low values (<160dB/Hz) which move around randomly and...

I'm writing a code in Python to capture data using a Picoscope 5000 series. I've been comparing the results of my code output with the output from the Picoscope software to check the accuracy, and it looks like there is a scaling factor of sqrt(2) that the signal needs to be multiplied by to get the...
