For the spectrum analyzer example at time 11:34, the input impedance of the dynamic signal analyzer has been set to 1MOhm. Spectrum analyzers only have a 50Ohm input impedance (and this cannot be changed in most spectrum analyzers unlike oscilloscopes). I suppose this method cannot be used then? Even an external 1MOhm adapter would not work as the signal being measured by the analyzer would still be across the internal 50Ohm of the analyzer.
Thank you for the great video.
This series has been absolutely insightful! There are still more videos to go but I had to comment this!
