Use the NI-RFSA Acquisition VIs to control acquisition operations with your vector signal analyzer.

niRFSA Read Power Spectrum (Cluster) VI
Initiates a spectrum acquisition and returns power spectrum data.
niRFSA Read IQ VI
Initiates an acquisition and fetches a single I/Q data record. Do not use this VI if you have configured the device to continuously acquire data samples or to acquire multiple records.
niRFSA Initiate VI
Commits settings to hardware, waits for hardware settling, and starts an acquisition. You can use this VI in conjunction with the niRFSA Fetch IQ VI to retrieve acquired I/Q data, or you can use the niRFSA Read IQ VI to both initiate the acquisition and retrieve I/Q data at one time.
niRFSA Fetch IQ VI
Transfers acquired waveform data from device memory to computer memory; this process is also known as fetching. The data transferred was acquired to onboard memory previously by the hardware after the acquisition was initiated.
niRFSA Abort VI
Stops an acquisition previously started with the niRFSA Initiate VI or the niRFSA Read Power Spectrum (Cluster) VI. You can also use the niRFSA Abort VI to stop a self calibration. Calling this VI is optional, unless you want to stop an acquisition before it is complete or you are continuously acquiring data.
