Frequency and Bandwidth Configuration with NI RF Drivers

You can use the NI-RFSA and NI-RFSG drivers to configure PXIe-5842 instruments for optimal performance by specifying frequency and bandwidth constraints.

The following table shows equivalencies between the NI-RFSA and NI-RFSG properties that control various elements of instrument frequency and bandwidth.
