LPF (Low-pass Filtering)
The low-pass filtering (LPF) is an independent digital low-pass 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 low-pass filtering. The following two
screenshots show the difference between waveforms with the low-pass filtering and
waveforms without the low-pass filtering.
