HP34970A

[Frida]

Hi,

I am working with the HP 34970A instrument togehter with labview. I have a VI "HP34970A Conf Trigger.vi" that comes with the toolkit I can download from your site. But the description/help for the VI is a bit poor. It says I can use this VI to control the scan interval for example. But I can seem to get it work. This Vi has 9 parameter inputs and I have tried some differnet combinations (the most resonable, I thought), but none of them is right (apperently). I would like to be able to control the scan interval from my main VI through a shared variable.

Does anyone have any idea how to configure this VI to make the scan controlling work??

I'll be glad for any help!

are you using NI's IEEE card to connect the HP 34970A to your computer?  I think the NI drivers only work with their own hardware cards.  I used an IOTech card on mine, so I had to write my own IEEE commands.

Have you looked at the HP34970A Advanced Scan Example VI? What part of the documentation to you find confusing? Each control has it's own help information. Do you want to control when a scan takes place, how many scans to make, the time between scans, or something else? You also have the HP34970A Conf Scan function that determines other scan parameters. One thing you can do is manually set up a scan from the instrument's front panel and set the front panel Boolean labeled Set/Check to true and run the VI three times - setting the Check Parameter control to the different options. Each query will return a value in the Configuration? indicator. In fact, most of the functions in the driver have a Check/Set input that makes it easy to set an instrument up manually and see what the corresponding commands are.
