Hi,
Perhaps the problem is caused by the Instrument itself, did you ask the R&S support for some support? Also the driver on the R&S hompage should be identical to the one you can get in the driver-liberary.
The UPV-Firmware itself:
Are you using the current Firmware 2.1.1.261? If your Firmware should be 1.something call R&S for a update-CD. First Versions were kind of buggy and instable during remote-control operation. (And a lot of measurements are missing also).
I do not know if writing a own driver using the GPIB commands will help. If you want to try it, there is a function you can use to create a setup:
If you start the "Scipi Recording" situated in the "Sequence"-menu all changes made on the UPV-settings will be recorded with in a editor-window with their command-lines you will need for VISA. But you will have to look up all other commands like "Trigger" or data-readout in the programming manual.
So it is depending how complex your application will be.
Greetings,
Florian

HI guys,
I need to communicate the UPV audio analyzer using GPIb in matlab or python? I have written code in python
import visa

UPV=visa.instrument("GPIB::20");
UPV.write('*RST');

UPV.write('SOUR:FREQ 1.5 kHz')
UPV.ask('SOUR:FREQ?')......... It was showing error as VI_ERROR_TMO: Timeout expired before operation completed
