mkj Posted May 25, 2017 Share Posted May 25, 2017 Hi - I've been playing with the different options on the Network Analyzer and had a question: Selecting dB gives an output G = 20*log(VCh2/VCh1) Selecting Gain gives an output G= VCh2/VCh1 Why is peak and RMS both referenced back to Vsource? PEAK gives an output G = VCh2/(VCh1/Vsource) RMS gives an output (rms) G(rms) = VCh2/(VCh1/Vsource) Link to comment Share on other sites More sharing options...
attila Posted May 25, 2017 Share Posted May 25, 2017 Hi @mkj Having the Channel 1 used as reference (default checked under ch1 settings) characterises your circuit by eliminating the attenuation on Wavegen/Vsource: G1 (of Ch1) = VCh1/Vsource, G# (of other channels) = Ch#/Ch1, GdB = 20*log(G) Vpeak1 (of Ch1) = VCh1, Vpeak# (of other channels is compensated) = Ch# / G1 When "Use as Reference" is unchecked you get for all channels: G# = VCh#/Vsource, Vpeak# = VCh# Link to comment Share on other sites More sharing options...
