The power-on default selection is no ltering. The “lTC” eld in Section 8.4—Console “CAL” | “SET”
Command Fields and Values controls the current lter selection. The cutoff frequency (i.e. -3 dB frequency)
is dependent on the sample rate selection, which is dened in Section 4.3—Sample Rate. The cutoff
frequencies for the different sampling rates are listed in the following table.
