Error: Unexpected I/O data termination

[pmankow]

Hello,

I am utilizing Visa with the Keysight 34980A. I can communicate with the device and send many commands but when I try and send a simple clear or reset command (lead by an asterisk) like "*CLS" or "*RST" I receive the error: "Error: Unexpected I/O data termination". The command does not work either. This can be seen in the attached image.

Does anyone know what the issue is or at least an explanation of the meaning of this error?

Thank you.

To debug issues like this, I would use NI-MAX to manually do what your code is doing.

This takes the Visual Studio stuff out of the picture.
