PSM1700 PsimetriQ user manual
15-3
Although it is most usual to use the PsimetriQ generator
when making harmonic measurements, there may be
circumstances where this is impractical, for example
measuring harmonic currents drawn from the mains. In
this case, turn off the PsimetriQ generator (OUT menu)
and the frequency reference for the analysis is measured
from channel 1. Provided that the signal is clean enough
for an accurate frequency measurement (and for DFT
analysis the frequency does need to be accurately known),
then the measurements can be made reliably.
When using an external frequency reference there can be
no sweep function.
