IviRFSigGen_ConfigureTDMAClockSource
IviRFSigGenTDMABase Capability Group
C Function Prototype
ViStatus IviRFSigGen_ConfigureTDMAClockSource (ViSession vi, ViInt32 source, ViInt32 type);
Purpose
This function configures the TDMA clock source.
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 the clock signal used to generate the digital modulation according to the selected standard. The driver uses this value to set the IVIRFSIGGEN_ATTR_TDMA_CLOCK_SOURCE attribute. Defined Values: IVIRFSIGGEN_VAL_TDMA_CLOCK_SOURCE_INTERNAL - The internal clock generator is used. IVIRFSIGGEN_VAL_TDMA_CLOCK_SOURCE_EXTERNAL - A connected external clock generator (bit or symbol clock frequency) is used. Default Value: IVIRFSIGGEN_VAL_TDMA_CLOCK_SOURCE_INTERNAL |
| type | ViInt32 | Specifies the type of the external clock signal used to generate the digital modulation. This value is used only if the IVIRFSIGGEN_ATTR_TDMA_CLOCK_SOURCE attribute is set to External. Type is ignored if Source is set to Internal. Defined Values: IVIRFSIGGEN_VAL_TDMA_EXTERNAL_CLOCK_TYPE_BIT - The external clock frequency is equal to the bit clock frequency of the digital modulation. IVIRFSIGGEN_VAL_TDMA_EXTERNAL_CLOCK_TYPE_SYMBOL - The external clock frequency is equal to the symbol clock frequency of the digital modulation. Default Value: IVIRFSIGGEN_VAL_TDMA_EXTERNAL_CLOCK_TYPE_BIT |
