I used Labview-based driver (5.0 version) to talk with HP 54110D Digitizing Oscilloscope, and the driver was from NI company. I bought a 82357A USB/GPIB Interface cable (a product from Agilent Tech.), and I followed the user's guide, and I sured that I suceed in installing the driver, and checked the cable and it was in good condition and then connect with the Oscilloscope, but there is no response when I run it's driver. I want to know how to solve this problem?
Though the interface of oscilloscope is HPIB, there should no problem to connect GPIB.
Sincerely,
Linghui

To be sure everything is connected and working properly, I would propose that you run a check by sending the string "*IDN?" to the device to see if it answers (you can use MAX for this purpose). If it works, you should see the name of your osccillo.

If not, try to shut down and restart Labview and the oscillo to reset the GPIB interface and do that again.

- check the GPIB adress of your device

Cheers.

Hi Linghui,

The most probable thing is that the driver that you are using for the HP54110D is using VISA. If that is true, then you are supposed to use HP-VISA instead of NI-VISA. Now, there is one passport that you can enable in NI-VISA that works for HP boards and that might work for your USB/GPIB. Open MAX (Measurement and Automation Explorer), go to tool» NI-VISA» Visa-Options» Passports and enable the Tulip passport. Once enable you should be able to use NI-VISA. If it doesn't work then uninstall the NI-VISA and install HP-VISA.
Hope this helps.
