:SOURce:WTYPe
Command Syntax
:SOURceN:WTYPe {CLOCk | DATA | FUNCtion | FILE}
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:WTYPe?
Query Response
{CLOCk | DATA | FUNCtion | FILE}
Description
On Arbitrary Waveform Generator (AWG) and simulated extended modules, specifies the type of source waveform using the following arguments. Use the :SOURce<N>:OENable command to enable the waveform. To display the source waveform that has been enabled, use the :CHANnel<N>:DISPlay command.
CLOCk- Selects a clock waveform.
DATA- Selects a data waveform. The pattern for the waveform is selected using the
:SOURce<N>:PATTerncommand. FUNCtion- Selects a waveform function, such as a sine wave. The actual function used to derive the source waveform is selected using the
:SOURce<N>:FUNCtioncommand. This parameter is not available for AWG extended modules. FILE- Configures a waveform using a pattern waveform file (.csv) or waveform file (.wfmx). Load the file using the
:SOURce<N>:FNAMecommand. This parameter is not available for AWG extended modules.
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.
