EME Posted June 9, 2016 Share Posted June 9, 2016 A question regarding the 2-channel spectrum analyzer in "Analog Discovery 2": Is it possible to measure/calculate "multi channel functions" like Frequency Response Function (Transfer Function), Cross spectrum and Coherence ?

attila Posted June 9, 2016 Share Posted June 9, 2016 Hello, I think you are looking for the Network Analyzer instrument of WaveForms. In this instrument the excitation signal is generated by the AWG, but it can rely on custom or external signal too. By default scope channel 1 is used as reference and the other channel(s) (channel 2 of Analog Discovery) measure relative value to this. The latest version of WaveForms 2015 supports custom functions to calculate capacitance, impedance... or other traces. The functions have the following parameters: frequency step, gain, magnitude, phase, real and imaginary parts.https://reference.digilentinc.com/waveforms3 On the other hand the data can be exported and processed in other toosl, or the device accessed from these using the SDK or WaveForms VIs for LabView https://decibel.ni.com/content/docs/DOC-44838 Link to comment Share on other sites More sharing options...
