Any drivers for Tektronix DMM4050 communication via GPIB-USB-HS?

[Persona12]

Hello everybody!
Are there any High-level drivers dedicated for Tektronix DMM4050 communication via GPIB-USB-HS?
I tried to find it here
http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=16512

But there are only drivers for RS232.
I have found some built in GPIB subVI's in Labview, but they are only low-level subVI's. So I need to build my own drivers.

No need to build your own driver, as the link says its for IEEE 488 and RS232.  That driver is based on VISA, so you may use RS232 or GPIB or Ethernet or USB depending on what connections your DMM provides.  Here's a screen cap of one of the examples.  See the "VISA resource name" control has the GPIB address of the device, if you select this you can ignore the RS232 settings as they won't be used.

To use the driver you will also need to have installed NI-VISA and NI-488 drivers.

Have you tried this driver and not had any luck communicating with the device?  If so you should review your physical setup by using NI-MAX to make sure your PC sees the GPIB-USB-HS and then can connect to the instrument over GPIB.  If you are having issues with this then check if you've installed other versions of VISA (Keithley, Tektronix, Keysight/Agilent, NI, etc..)  These often get installed if you install Keysight I/O, or Keithley/Tektronix software.   If another version of VISA is set as default then LabVIEW wouldn't be able to use NI-VISA.   Look around the forums for solutions that refer to the VISA Tulip passport - https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P9t6SAC&l=en-CA

Thank you for all your suggestions! My problem was that at first there was no GPIB instument in a Visa Resourse Field. Later some of the DMMs (I have 3) appeared, others no. Later they appeared and then dissapeared in a completely random way. Another problem was that when I wanted to choose an instrument in the Visa Resourse Field while GPIB was conected, the whole program has lagged.
So I have found and reinstalled all the drivers from NI regarding GPIB (NI 488.2) and I also has installed all the possible updates. Now everything looks fine. At least for now.
