Please help with THD measurement.
To get a THD measurement result (something other than "Incomplete"), the source must be a FFT (frequency domain) waveform that displays the fundamental frequency, at least one harmonic, and a frequency range that contains a width of 1/2 the fundamental frequency around the fundamental frequency and around each harmonic you want to include in the measurement.
If the Tracking parameter is "Auto", the highest peak is assumed to be the fundamental frequency. If the Tracking parameter is "Manual", you can use the Fundamental parameter to specify the fundamental frequency.
Thanks much. I simply didn't realize that THD function operated on the FFT trace, so FFT had to be displayed first. DUH.
