INPut:FILTer[:LPASs]:FREQuency <cutoff_freq>,(@<ch_list>)

sets the cutoff

frequency of the filter on the specified channels.

Parameters

Comments

The parameter may be specified in kilohertz (kHz). A

programmable Filter in either an SCP or a Remote Signal Conditioning unit
(RSC) has a choice of several discrete cutoff frequencies. The cutoff frequency
set will be the one closest to the value specified by .

For the VT1529A/B, this command affects an 8-channel bank, not a single

channel.

Sending MAX for the selects the SCP or RSC's highest cutoff

frequency. Sending MIN for the selects the SCP or RSC's lowest
cutoff frequency. To disable filtering (the "pass through" mode), execute the
INP:FILT:STATE OFF command.

Sending a value greater than the SCP's highest cutoff frequency or less than the

SCP's lowest cutoff frequency generates a -222 "Data out of range" error.
