I have used Analog Discovery 1 extensively for various audio measurements (Bode plots, photonic measurements, scope noise measurements etc.) and have just started to use the Waveforms Spectrum Analyzer. I have made quite a few real-time noise measurements using a very low noise well calibrated 24 bit/96kHz sound card down to the uVrms level using a steep 46kHz low pass filter and also a similar 20kHz 5th order LPF. So these are time-domain analog measurements within a well defined "noise bandwidth". With sufficiently high noise levels (say +20mVrms well above the ~ 0.5mV noise floor of the Di
