Description
Specifies the source of the Sample Clock timebase, which is the timebase used to control waveform sampling.
Defined Values:| NIRFSA_VAL_ONBOARD_CLOCK_STR | The digitizer uses its onboard clock as the Sample Clock timebase. |
| NIRFSA_VAL_CLK_IN_STR | The digitizer uses the signal present on the CLK IN connector as the Sample Clock timebase. |
| NIRFSA_VAL_DOWNCONVERTER_LO2_OUT_STR | The digitizer uses the signal present on the LO2 OUT connector on the downconverter as the Sample Clock timebase. This value is supported only for the PXIe-5668. |
| NIRFSA_VAL_LO_REF_CLK_STR | The digitizer uses the signal generated on the 100 MHz REF OUT terminal on the PXIe-5653 as the Sample Clock timebase. This value is supported only for the PXIe-5665. |
| NIRFSA_VAL_PXI_STAR_STR | The digitizer uses the signal present at the PXI star trigger line as the Sample Clock timebase. This value is not supported for the PXIe-5668. |
Default Value: NIRFSA_VAL_ONBOARD_CLOCK_STR
Supported Devices: PXI-5661, PXIe-5663/5663E/5665/5667/5668
