RFmxInstr Initialize from NIRFSA Session VI
- Updated2025-10-13
- 2 minute(s) read
Initializes an RFmx session from an existing NI-RFSA session. This VI resets all NI-RFSA properties to their default values and stops export of all the external signals and events. This VI also takes in an active NI-RFSA session and returns an RFmx Handle that identifies the device in all subsequent RFmx VIs.
Note
- Do not close the NI-RFSA driver session before calling the RFmxInstr Close VI. Closing the NI-RFSA driver session before closing RFmx session would lead to unpredictable behavior.
- Closing the RFmx session will not close the NI-RFSA driver session.
