suktan Posted January 30, 2019 Share Posted January 30, 2019 I want to do frequency response measurement using external excitation signal. Is it possible? The network/impedance analyzer seems limited to using Wavegen to generate excitation signal. Spectrum doesn't seem to allow math operation of FFT CH1/FFT CH2. Any suggestion?

attila Posted January 30, 2019 Share Posted January 30, 2019 Hi @suktan In the Network Analyzer you can select to rely on external excitation signal. Link to comment Share on other sites More sharing options...
suktan Posted January 31, 2019 Author Share Posted January 31, 2019 Thank you! How can I add trigger condition? The excitation is an impulse. Link to comment Share on other sites More sharing options...
attila Posted January 31, 2019 Share Posted January 31, 2019 Hi @suktan No. The NA performs untriggered captures and looks for peak on scope channel 1 which will consider as current frequency step. It expects an external slow sweep. You could eventually use the Script tool and process the data FFT1/FFT2, from triggered Scope or Spectrum, see: Link to comment Share on other sites More sharing options...
