Remarks


NI-RFSG may introduce a frequency error up to the specified amount to optimize computational speed and onboard memory usage while upconverting phase-continuous signals.

If the NIRFSG_ATTR_PHASE_CONTINUITY_ENABLED attribute is set to NIRFSG_VAL_DISABLE, the NIRFSG_ATTR_FREQUENCY_TOLERANCE attribute is ignored, and the driver does not introduce a frequency error. On devices that do not use software upconversion, this attribute is ignored. The PXI-5670 always uses software upconversion, and the PXI-5671 uses software upconversion for I/Q rates greater than 8.33MS/s.

To set this attribute, the NI-RFSG device must be in the Configuration state.

Units: hertz (Hz)

Default Value: 50

Supported Devices: PXI-5670/5671
