Figure 49. Waveform Sampling Window
The waveform sampling window allows you to view multiple
waveforms in the signal chain, including the current, voltage,
active, reactive and apparent multiplier outputs, along with the
output of the IRMS LPF. The samples are taken at a speed of
3.2 kSPS. The number of samples is defined by adjusting the
value in the
Buffer Length
box.
