:SOURce:FILTer:TYPE
Command Syntax
:SOURceN:FILTer:TYPE {BESSel4 | BUTTerworth1 | BUTTerworth2 | BUTTerworth3 | BUTTerworth4}
Where N identifies a simulated module's specific channel and must be selected from {1:8}{A|B|C|D}. For example, SOURce3C
.
Query Syntax
:SOURceN:FILTer:TYPE?
Description
On Arbitrary Waveform Generator (AWG) and simulated extended modules, specifies the type of filter that can be applied to the indicated source waveform. Use the :SOURce<N>:FILter:CUToff
command to specify the filter's cutoff frequency. Use the :SOURce<N>:FILter:STATe
command to apply or remove the filter.
BESSel4
- 4th order Bessel filter
BUTTerworth1
- 1st order Butterworh filter
BUTTerworth2
- 2nd order Butterworh filter
BUTTerworth3
- 3rd order Butterworh filter
BUTTerworth4
- 4th order Butterworh filter
Requires FlexDCA revision A.02.00 and above for simulated extended modules. Revision A.06.00 and above for AWG extended modules.

Selecting AWG Channels
When sending a :SOURce
subsystem command to an AWG, the method used to specify the AWG's channel may look confusing at first glance. This is because, the AWG's front-panel channels are labeled 1, 2, 3, and 4, but FlexDCA identifies channels with letters (A, B, C, or D). As a result, you must convert the AWG's channel number to an equivalent FlexDCA letter. For example, to enable channel 3 of an AWG that is installed in FlexDCA's slot 5 use the following command: :SOURce5C:OENable ON
.
