C Function Prototype

ViStatus IviFgen_ConfigureFMSource (ViSession vi, ViConstString channelName, ViInt32 source);

Purpose

Configures the source of the FM modulating waveform.

Parameters

Name Type Description
vi ViSession The instrument handle that you obtain from the IviFgen_init or IviFgen_InitWithOptions functions. The handle identifies a particular IVI session.
channelName ViConstString Pass the virtual channel name that you assign to the instrument in MAX.

Virtual channel names are aliases for instrument specific channel strings. The instrument specific channel strings can differ from one instrument to another. Virtual channel names allow you to use and swap instruments without having to change the channel names in your source code. You assign a virtual channel name to an instrument specific channel through MAX. This control accepts virtual channel names you have assigned to the specific instrument you are using. It also accepts the instrument specific channel names.

Note  You can specify the channel name as a string variable or as a literal enclosed in double quotes.
source ViInt32 Specify the frequency modulation waveform source you want to use. The driver uses this value to set the IVIFGEN_ATTR_FM_SOURCE attribute.

Defined Values:

IVIFGEN_VAL_FM_INTERNAL

IVIFGEN_VAL_FM_EXTERNAL
