Comments
•
<
cutoff_freq
>
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 you are programming.
•
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
INPut:FILTer:LPASs:STATe OFF
command.
•
Sending a value greater than the SCP’s highest cutoff frequency or less than the
SCP’s lowest cutoff frequency generates Error -222, “ Data out of range” error.
•
This command will cause Error +3000, “ illegal while initiated” if trigger is initiated.
