VXi VT1529A/B 사용자 설명서

The INPut subsystem controls configuration of programmable input Signal 
Conditioning Plug-Ons (SCPs).

sets the cutoff 

frequency of the filter on the specified channels.

•

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.
