·
The <cutoff_freq> parameter may be specified in kilohertz (kHz). A
programmable Filter SCP has a choice of several discrete cutoff frequencies. The
cutoff frequency set will be the one closest to the value specified by
<cutoff_freq>. Refer to Chapter 6 for specific information on the SCP being
programmed.
·
Sending MAX for the <cutoff_freq> selects the SCP’s highest cutoff frequency.
Sending MIN for the <cutoff_freq> selects the SCP’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.

*RST Condition: set to MIN
Usage INP:FILT:FREQ 100,(@140:143) Set cutoff frequency of 100 Hz for channels
40 through 43
INPUT:FILTER:FREQ 2,(@155) Set cutoff frequency of 2 Hz for channel 55
INPut:FILTer[:LPASs]:FREQuency?
INPut:FILTer[:LPASs]:FREQuency? (@<channel>) returns the cutoff
frequency currently set for <channel>. Non-programmable SCP channels may be
queried to determine their fixed cutoff frequency. If the channel is not on an input
SCP, the query will return zero.
