IviRFSigGen_ConfigureDigitalModulationBaseDataSource
IviRFSigGenDigitalModulationBase Capability Group
C Function Prototype
ViStatus IviRFSigGen_ConfigureDigitalModulationBaseDataSource (ViSession vi, ViInt32 source);
Purpose
This function configures the source of the data for the digital 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 |
| source | ViInt32 | Specifies the source of data. The data is used to modulate the RF signal according to the standard selected with the IVIRFSIGGEN_ATTR_DIGITAL_MODULATION_BASE_SELECTED_STANDARD attribute. The driver uses this value to set the IVIRFSIGGEN_ATTR_DIGITAL_MODULATION_BASE_DATA_SOURCE attribute. Defined Values: IVIRFSIGGEN_VAL_DIGITAL_MODULATION_BASE_DATA_SOURCE_EXTERNAL - The data from an external device connected to the instrument is used. IVIRFSIGGEN_VAL_DIGITAL_MODULATION_BASE_DATA_SOURCE_PRBS - The internal PRBS (Pseudo Random Binary Sequence) generator is used as data source. IVIRFSIGGEN_VAL_DIGITAL_MODULATION_BASE_DATA_SOURCE_BIT_SEQUENCE - A constant bit sequence is used as data source and repeated continuously. Default Value: IVIRFSIGGEN_VAL_DIGITAL_MODULATION_BASE_DATA_SOURCE_EXTERNAL |
