channels)
Free Run Configuration
For THD analysis, a barchart display is created for each output channel showing the instantaneous THD
of the EUT.
For individual harmonic amplitude, a graph is created with a trace for each output channel showing the
relative harmonic amplitude as a function of harmonic number:
For distortion FFT, a graph is created showing the spectrum of the EUT output with the fundamental
removed:
Sweep Configuration
For THD analysis, a graph is created showing THD vs. frequency. A new trace is created for each
amplitude specified in the amplitude sweep. For the other analysis modes, graphs similar to the free run
graphs are created, the difference being that as the amplitude sweep progresses a new trace is created
for each amplitude value in the sweep.
