The pop up menu of “VISA resource name” comes nothing except refresh.

[PeterChen]

I need help!

I connect the Agilent 33220A to my computer through Agilent 82357B USB-GPIB cable. Both Agilent connection expert (Agilent IO control) and NI-MAX can detect the equitment and query the *IDN? successfully. I when I want to use the driver example in lab view 2015 (Agilent 33xxx series), the pop up menu of “VISA resource name” comes nothing except refresh.

I already reinstall NI-VISA driver even the whole Lab View package, but it not work. Below shows my MAX (GPIB::10::INSTR is 33220A).

Check whether GPIB Interface drivers are installed while installing Device Drivers?

Install the drivers from here and then see if it works: http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0470714759413BCCE0440003BA7CCD...

Right click on the VISA control and check what settings are present under I/O Name Filtering.

Hi Peter,

what happens when you replace the VISA IO control with a simple string constant containing "GPIB0::10::INSTR" (without the quotation marks)?

It shows this

Now the situation is both MAX or Agilent IO can find 33220A, but in Lab View, it can not find 33220A, I do not know why and what should I do.

Please help!

Thanks for answering me.

I bought the 82357B USB-GPIB cable, and installed the Agilent IO control software, Is it the GPIB interface drivers?

I can query *IDN? successfully and MAX also can find USB-GPIB, is it means the USB-GPIB works well?

The problem is that the labview program can not find it.

Thanks for you remainder.
