Agilent MSO7014A: IVI/VISA connection fails with error 0xBFF0079

[mju_]

Hello,

I'm trying to access an Agilent MSO7014A oscilloscope using NI's AG6000 IVI driver.

I've installed the driver and configured the hardware using "TCPIP0::192.168.1.151::INSTR" as the VISA resource descriptor. LAN control is enabled in the device setup.

When I try to connect, the connection fails with error 0xBFF0079 (Invalid protocol).

NI Spy log:

I guess that the resource descriptor is not fully correct but I don't have a clue what to change here. Does anyone of you has an idea?

Thanks,

Are you able to ping the Agilent scope?

[mju_]

Yes, I am. I can access the web front-end as well, so the ip setup seems to be okay.

[Dennis_Knutson]

Are you sure the instrument is using VXI-11/LXI? That is what is required for an INSTR connection. Have you tried a raw socket connection?

[mju_]

Yes, the instrument is using LXI.

I haven't been able to open a socket connection to port 5025 either. So I double-checked the lan control option.

I don't know if why but when I disable lan control and re-enable it, port 5025 is open. Then LXI is working is well.

Thanks for your help!
