Agilent/Keysight 33250A using GPIB to USB converter

Hello all,

my question aims at the usage of the Keysight (former Agilent) 33250A frequency generator with a GPIB to USB converter "between" device and pc. I can use the NI-MAX VISA testpanel to write a simple command like "FREQ 3" to the device. This works w-o a problem as well as with the I/O-suite of Keysight which is necessary referring to the following application note:
http://literature.cdn.keysight.com/litweb/pdf/5990-3731EN.pdf
When using a VI with the simple commands "VISA open" , "VISA WRITE", "VISA CLOSE" I get the following error message:
VISA Open in FG-33250-set_frequency.vi
The program as well screenshots of the NI-MAX, the Keysight I/O-suite (showing device is connected and works) and the trace (line 6-26: command given from NI-MAX, line 1-5: testing GPIB-adresses, line 27,28: testing given alias) are attached.

I got nearly the same problem a month ago with Labview '17 running. Two weeks later I installed Labview '18. Yesterday I checked my main program and got the error as described above. Support from Agilent said it might be a installation problem. So Labview completely deinstalled and installed only Labview'18 with the concerning VISA-palette and the Keysight I/O-suite in the right order.

Thanks in advance for solutions!
Tom

What is the error message you get? I think you left it out.

 

Based on the MAX screenshot, it looks like you might be missing some drivers for the GPIB adapter.

Hello grogoryj,

thanks for the reply.
Driver for the adapter is not the problem. Error message is right.
Error code is the following:

Ok, did you try using this article to troubleshoot yet?

I am using LV 2016, so if you do "file >> save for previous version..." I can take a look at the VI

For Agilent/Keysight USB-GPIB you need to make sure the NI-VISA Passport for TULIP is enabled (it is disabled by default)

 

Open NI MAX

Navigate to Tools---->NI VISA---->VISA Options

Select Passports from the tree

Check the box to enable NiVisaTulip.dll -- NI-VISA Passport fo Tulip
