LPF (Lowpass Filtering)
The lowerpass filtering (LPF) is an independent digital lowpass filter for each input
channel used to remove noise from the signal.
It is helpful to find and reject low frequencies from the selected input channel for
more accurate measurements. Take the two screenshots below as an example to
show the comparison with or without setting the lowpass filtering. Figures 8-45 and
8-46 show the difference between waveforms with the lowpass filtering and
waveforms without the lowpass filtering.
NOTE
The lowerpass filtering (LPF) is only available via USB connection.
