No instrument found in test and measurement tool despite successful query between tekVISA and tool.

I am trying to communicate with a tektronix waveform generator (AWG) using matlab2015a, 32 bit. Have installed tekVISA version 4.1.1, and have connected via VXI-11 LAN using the IP address of the AWG which was put in server mode. Open Choice Talker Listener shows successful communication between this laptop and the AWG.

When I open the test and measurement tool in matlab, and scan for a TCPIP (VXI-11) device there is none found.

instrhwinfo visa gives:

ans = 

HardwareInfo with properties:

    InstalledAdaptors: {'ni'}
       JarFileVersion: 'Version 3.7'

Can anyone tell my why matlab can't detect the AWG despite successful connection with the VISA software?

Hello Kaitlyn,

Try connecting it instead using the VISA-TCPIP Object.

I suffered from the same problem, and the fix is: 1. make sure TEKVISA interface is the selected preferred VISA interface (run VISA64 Conflict Manager) 2. restart Matlab Hope it helps.
