Issue

If you are unable to connect to an RF signal generator the following table offers troubleshooting steps.

Possible Solutions

Error ScenarioPossible Solution

Support package not installed

Ensure that the necessary support packages is installed, available in the Add-On Explorer.

Additionally, Instrument Control Toolbox Support Package for IVI and VXIplug&play Drivers requires a VISA driver and the IVI Compliance Package to be installed. Install the Instrument Control Toolbox Support Package for VISA and ICP Interfaces from the Add-On Explorer.

For detailed instructions, see Install Instrument Control Toolbox Support Package for IVI and VXIplug&play Drivers.

If using NI-RFSG with rfsiggen:

  • MATLAB driver not installed or invalid

  • If driver name provided, make sure it is valid

There might be an issue with the MATLAB driver currently installed on your system. Ensure you have installed the correct MATLAB driver that corresponds to the input provided to your ividev function.

Verify that NI-RFSG shows up in the IVI driver list output by using the command:

ividriverlist

Wrong resource name or driver name

When creating instances of fgen, rfsiggen, and scope, review the available drivers and resources by using the resources and drivers functions, and use those which are listed. For example:

f = fgen();
resources(f)
      ASRL3::INSTR
      ASRL::COM3
      Dev1
      Dev2
drivers(f)
     Driver: Agilent332x0_SCPI
     Supported Models:
     33210A, 33220A, 33250A
     
     Driver: nisFgen
     Supported Models:

Mismatched resource name with API

Ensure that the function generator (fgen), RF signal generator (rfsiggen), and oscilloscope (scope) APIs are correctly paired with their respective drivers and resources.
