Specifies the reference clock source. To set this attribute, the NI-RFSG device must be in the Configuration state. Only certain combinations of this attribute and the NIRFSG_ATTR_PXI_CHASSIS_CLK10_SOURCE attribute are valid, as shown in the following table.

NI 5670/5671 devices also allow you to drive the PXI 10 MHz backplane clock on PXI chassis only using the NIRFSG_ATTR_PXI_CHASSIS_CLK10_SOURCE attribute.

Value	Description
NIRFSG_VAL_ONBOARD_CLK_STR	Use the onboard reference clock as the clock source.
NIRFSG_VAL_REF_IN_STR	Use the clock signal present at the front panel REF IN connector as the clock source.
NIRFSG_VAL_PXI_CLK10_STR	Use the PXI_CLK10 signal, which is present on the PXI backplane, as the clock source.
