4.5 Low-Pass Filter
The power-on default selection is no filtering. The “filTC” field in
Section 8.4—Console “CAL” | “SET”
controls the current filter selection. The cutoff frequency (i.e. -3 dB frequency)
is dependent on the sample rate selection, which is defined in
. The cutoff
frequencies for the different sampling rates are listed in the following table.
