nirfsa module

Installation

As a prerequisite to using the nirfsa module, you must install the NI-RFSA runtime on your system. Visit ni.com/downloads to download the driver runtime for your devices.

The nimi-python modules (i.e. for NI-RFSA) can be installed with pip:

$ python -m pip install nirfsa

Usage

The following is a basic example of using the nirfsa module to open a session to an RF Signal Analyzer and perform a spectrum acquisition.

import nirfsa

# Configure the session
with nirfsa.Session(resource_name='5841', id_query=False, reset_device=False, options='Simulate=1, DriverSetup=Model:5841') as rfsa_session:
    rfsa_session.acquisition_type = nirfsa.AcquisitionType.IQ

    rfsa_session.reference_level = -10
    rfsa_session.iq_carrier_frequency = 1e9

    iq_data_array = np.zeros(1024, dtype=np.complex128)

    wfm_info = rfsa_session.read_iq_single_record_into(iq_data_array)
    # Perform measurements...

Other usage examples can be found on GitHub.
