Error -380205 when using RFmxInstrMX with ‘Simulated=1’

[chohsintsai]

I wanted to simulate (i.e., not using the physical hardware) the device of NI PXIe-5840 Vector Signal Transceiver (VST). I executed the following command in MATLAB:

NET.addAssembly('NationalInstruments.RFmx.InstrMX.Fx40');

import NationalInstruments.RFmx.InstrMX.*;

InstrMXHandle = RFmxInstrMX(‘VST_01’, ‘Simulate=1,DriverSetup=Model:5840'); % This is where the error occurred

I got the following error message:

Error using NIRFmxDriver

Message: NationalInstruments.RFmx.InstrMX: -380205: An interaction with LabVIEW has caused the following error:

Error code: -380205

identifier: 'MATLAB:NET:CLRException:CreateObject'

Source: NationalInstruments.RFmx.InstrMX.Fx40

Below is the software I have already installed:

1. NI RFmx SpecAn software
2. NI-RFSG software
3. NI-RFSG Playback Library software

I was wondering if I missed installing some required software, or the way I used the API was incorrect.

Any help would be much appreciated. Please feel free to let me know if you need more information. Thank you for your time and effort.
