IviRFSigGen_ConfigurePMExternalCoupling
IviRFSigGenModulatePM Capability Group
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 |
