C Function Prototype

ViStatus IviRFSigGen_ConfigurePMExternalCoupling (ViSession vi, ViInt32 pmExternalCoupling);

Purpose

This function configures the coupling of an external source for phase modulation.

Parameters

Name Type Description
vi ViSession The ViSession handle that you obtain from the IviRFSigGen_init or IviRFSigGen_InitWithOptions function. The handle identifies a particular instrument session.

Default Value: None

pmExternalCoupling ViInt32 Specifies the coupling of the external source of the modulating signal. The driver uses this value to set the IVIRFSIGGEN_ATTR_PM_EXTERNAL_COUPLING attribute.

Defined Values:

IVIRFSIGGEN_VAL_PM_EXTERNAL_COUPLING_AC
- The external source is coupled for AC only.
IVIRFSIGGEN_VAL_PM_EXTERNAL_COUPLING_DC
- The external source is coupled for both DC and AC.

Default Value: IVIRFSIGGEN_VAL_PM_EXTERNAL_COUPLING_AC

Return Values
