VISA or GPIB Drivers logging

[asergeev2001]

Hello,

I am looking for a possibility to get some logs from VISA or GPIB drivers. Like which command was sent or which data come from the instrument. Something like what NI SPY provides.

Is this available? If yes Is there any API to start/stop logging and get logs?.

Thank you.

What programming language? You can launch NI I/O Trace (new name for NI-Spy) from LabVIEW.

We are using C#.

asergeev2001,

If you have LabVIEW installed, you could call the LabVIEW I/O Trace API to accomplish this.  You should also be able to call those functions using C# (Calling LabVIEW VIs from Other Languages: http://zone.ni.com/devzone/cda/tut/p/id/5719#toc3), and those VIs are located in .../Program Files/National Instruments/LabVIEW xxxx/vi.lib/NiIOTrace.

Will this get the functionality you're looking for?

Well. This could be a solution.
