Short Name: Frequency Tolerance (Hz)

Property of niRFSG

Specifies the allowable frequency error introduced during the software upconversion process. 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 Phase Continuity Enabled property is set to Disable, the Frequency Tolerance (Hz) property is ignored and the driver does not introduce a frequency error. On devices that do not use software upconversion, this property is ignored. The PXI-5670 always uses software upconversion, and the PXI-5671 uses software upconversion for I/Q rates greater than 8.33 MS/s. To set this property, the NI-RFSG device must be in the Configuration state.

Supported Devices: PXI-5670/5671

Default Value: 50 Hz
