notthetup Posted November 10, 2023 Share Posted November 10, 2023 Hello, I would like to measure the frequency response of a differential pre-amplifier which has a differential input and a differential output. Is it possible to use the 2 input and output channels of the Analog Discovery 3 to measure something like this? Link to comment Share on other sites More sharing options...
1 attila Posted November 10, 2023 Share Posted November 10, 2023 Hi @notthetup Yes. The Network Analyzer has option for differential drive on the two AWG outputs and the Scope inputs are differential. notthetup 1 Link to comment Share on other sites More sharing options...
0 notthetup Posted February 19 Author Share Posted February 19 Thanks @attila! I got my Analog Discovery 3 and tried out the differential output. It works well. However, I am struggling to measure a differential output in the Network Analyzer. I get the two plots in the Magnitude section, which I guess are C1/Source and C2/Source. But is there any way I can get the Magnitude (and Phase) of (C2-C1)/Source ? Thanks! Link to comment Share on other sites More sharing options...
0 attila Posted February 19 Share Posted February 19 Hi @notthetup By default Magnitude is Relative to Ref: Channel1 C1 = c1/Source C2 = c2/c1 and C2 phase is c2-c1 You also have Add Channel/ Math for Magnitude operations in gain unit. Link to comment Share on other sites More sharing options...
