:FILTer <string>
:FILTer?
To improve performance, one of four premodulation filters is 
automatically selected for each encoder mode. The automatically 
selected filter can be changed only by using GPIB commands. 
We recommend that you leave this setting at its automatically selected 
setting.
 
If it is necessary to override the automatic settings, the 
AFG2:FILT:MODE ‘ON’ command must be executed first (filter mode 
OFF is the power up default state.) The following error will occur if the 
user attempts to select an alternate filter without first setting the filter 
mode to ON: 
Entry not accepted.
 The syntax to change or query the 
premodulation filter is shown in the example below. 
Syntax
AFG2:FILT ‘None’
‘20 kHzLPF’
‘250 HzLPF’
‘150 HzLPF’
AFG2:FILT?
Example
AFG2:FILT:MODE 'ON' !turn filter selection mode on
AFG2:FILT:MODE? !query the current mode setting
AFG2:FILT 'NONE|20kHz LPF|250Hz LPF|150Hz LPF' 
  !select one to change the setting
AFG2:FILT? !query the new filter setting
