Error Connecting DPO7354 via VXI-11 LAN: 1073807346

Go to solution



I am new to Labview but experienced with computers, Python, C++, and other languages. 


I have been able to setup and detect my DPO7354 Oscilloscope thru VXI-11. I can successfully ping from both cmd prompts, write commands, query, and use the read command. But when I try to run the Tektronix 7000 Series Acquire, I get the following errors:


Error -1073807346 occurred at VISA Open in Tektronix 7000>Tektronix 7000 Series Acquire

Possible reason(s):

VISA: (Hex 0xBFFF000E) The given session or object reference is invalid.


I have googled this extensively. I have done the following: 

- Open all ports + disable Win firewall

- Set read from binary to hex so that I'm not bit limited (was stopping read on VISA Test Panel) 


But I still also get errors reading from the test panel: 

Read Operation

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.


It works fine after query but after I read through all the query data it reads that error. I can adjust the bitrate to make it through that data but that's it. 


Any ideas? It would help me troubleshoot this a lot if I knew it was a problem with connections, ports, data, my labView config, my .vi config, etc...


Thanks a ton

Did you fill in the exact same resource name in the example vi as in the visa session?

Resource name not valid suggests this.

Hello and thanks for the help, 


yes it was also labeled "inst0" in the vi editor


NI support thinks it couldve been an issue not using the right name, as in it has to have certain parameters


We will see tomo

Hello and sorry to bump my own post,


I am closer and closer to a solution.


I have isolated it to LabView not recognizing my VISA Resource Name. 


Has anyone had any similar issues and can offer a solution?


I have tried all types of names, examples:





and everything in between and all kinds of variations.

If anyone else ever has the problem:


Disable Tektronix VISA in Conflict manager.
