Multiple NI-Scope sessions

[Igottabanana]

Hi guys ,

I tried to find info in this forum but with no lucky.

I want to acquire data using a NI-Scope ( NI-PXI 5105 , 8 channels ) with two application (two different labview projects) simultaneusly.Application A acquire from channels number 0 and 1 and application B from the channel number 2.

When application B starts , it fails when tries to create the instrument handle session because : "Thedigitizer isbeing used by another application".

Is there a way to acquire data from different channels with two different application ?

Thanks,

Cesare

You would need one application that configures the instrument and acquires all of the channels. Publish the data with one of the above techniques.

I'd like to add that this is a good thing, in my opinion. Since there are configurations such as the time base, triggering, that are common to the instrument, you would not want one application to be able to change what a different application has set. You would not want one application to initiate a new acquisition while another application is in the middle of its acquisition. If you want the applications to be independent with full control, you need to wait until the other application is done with the instrument or use two different instruments.
