INPut:FILTer[:LPASs]:FREQuency
INPut:FILTer[:LPASs]:FREQuency <cutoff_freq>,(@<ch_list>) sets the cutoff
frequency of the filter on the specified channels.
Parameters
Comments •
The <cutoff_freq> 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 <cutoff_freq>.
•
For the VT1529A/B, this command affects an 8-channel bank, not a single
channel.
•
Sending MAX for the <cutoff_freq> selects the SCP or RSC's highest cutoff
frequency. Sending MIN for the <cutoff_freq> 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.
