LabView VI for SRS QMS RGA

[TomCoffey]

Hi all,

I was wondering if anyone has written a VI for a SRS QMS series residual gas analyzer. SRS no longer supports the labview VI that they wrote for the QMS series RGAs. The VI they have on their site stopped evolving at LV 7 and it also looks like it has a lot of extra bells and whistles that I am not interested in.

Thanks !

Hey Tom,

We've got a bunch of instruments from Stanford Research Systems on NI's Instrument Driver network (www.ni.com/idnet) but it unfortunately doesn't look like we have a driver for this particular instrument. Unless someone here on the forums happens to have written their own driver, you'll most likely need to stick with the LabVIEW driver provided by SRS. From looking at the driver it doesn't look like it has very many bells or whistles. Since it's actually just a simple API for the device, shouldn't you just be able to use what functions you need for your application and ignore the rest?

Hi Lars,

The Labview driver I downloaded from SRS didn't work. Even so, it's unclear how I would integrate the RGA data into my other datastream without doing a lot of  reading and writing to file. 

If someone out there has written a simple driver for the SRS QMS series RGA I'm still interested.

Thanks for your input.

Regards,

Tom Coffey

Running into a similar issue for the SRS RGA 100. The developer kit had an error in the Convert String to Units.vi. It failed to de-couple all cases from a unit. Once that was corrected, the vi's loaded. However, I am unable to get a proper connection to the RGA. Would love to know if anyone out here has toyed with this and come up with a solution. I know it was developed in LabView 7.0, and I'm using 2012... I'm not clear as to what would have changed in the VISA vi's that would have made connectioning unavailable... it actually states it makes a connection, but the RGA does not acknolwedge the connection.

I also need to decouple data from units in the RGA VI's.  I did not have any problems connecting to the RGA using the old style serial VI's.
