NI VISA with Tektronix TDS7404

[okissele]

Hi everyone,

I have problem connecting to Tektronix TDS7404 oscilloscope via Ethernet from LabView. The driver is installed, but when I open the example VI came with the driver,

I need to specify the VISA name. If I leave the field empty, I get an error:

Error -1073807343 occurred at VISA Open in Tektronix 7000
Series.lvlib:Initialize.vi->Tektronix 7000 Series Acquire Waveform.vi

Possible reason(s):

VISA: (Hex 0xBFFF0011) Insufficient location information or the device or
resource is not present in the system.

How should I configure the VISA for this scope?

It is connected to the PC via a switch, ping to the scope works, I can see the harddisk of it also.

I use LabView 2010 SP1; I do not see the scope in MAX also.

Thank you.

Hello,

thanks for the link.

I actually tried the recipe already. I opened MAX, added the new VISA TCP-IP in the Devices and interfaces. Typed the IP number of the scope (that works, ping goes fine) and the name associated to this IP.

Search for the device over network did not show it, so I created it manually. Did not work, no connection. I do not know how to find out a port number to try the communication via Raw Socket, so this I did not try.

Edit: nevermind. If a Ping works, the firewall isn't the issue.

Any idea what might be an issue? If ping works, firewall is set for all NI services to be free.

At my previous employer, we had the instrument and the PC on the same subnet, e.g. 192.168.1.xxx

Problem solved. One of the device drivers was not installed. Not the high-level (VISA drivers) but the low-level drivers. The TekVISA server on the scope was not running as well. Strange that LabView did not complain about these directly, just did not see the scope.

I am having the same issue.  What drivers did you end up installing?  I installed everything relevant in VISA 5.1.2 but I still cannot find it in MAX.
