Getting multiple data readings at one time using LabVIEW (GPIB) with the Fluke Hydra 2620A

I'm taking temperature readings with the 2620A using the NI LabVIEW drivers. Is there anyway to take an array of the data results? (i.e. more than one channel at a time)

Thanks.

This depends upon which VIs you are using. Are you using a driver specifically for the 2620A, the 488.2 VIs, or the VISA VIs? It also depends upon how the instrument returns data. You could use the array VIs in LabVIEW to parse the string and put it into an array, but first we'll need to know how it is sent back. For instance, it is long values separated by commas, etc. Let us know how the string is configured and we'll find a way to do it.

i'm using the NI driver for the 2620A. I can get data from one channel at a time that returns a string of values, separated by commas, but it's important that I can get the results from multiple channels at one time. Thanks.

About 10 years ago I built a GPIB Hydra application (in Labwindows at those days) that could read-out all channels, so it's doable.
If the driver is not sufficient I advise you to expand the existing driver by taking a look at the programming ref guide.
One point of notice: it is a switching relay instrument, so sampling at the same timestamp is an illusion.
