Is there any command to check the status of CWAI?

[DrObb]

I want to check if CWAI is currently on or off (start or reset or stop). Is there any convenient command to check?

No, there isn't a polling flag for this. You would need to use the events to keep track of it in your code. For example, you can use the progress and acquireData events to keep up with progress on a finite buffered operation. If you have a continuous operation, just use a variable as a flag that you set when you call start, stop or reset.

Hello

You can check up on the CWAIReadSpec which has a read only property called AcquisitionState. Check out the following following KB about how to use this object.

And you can check out the function details in the Measurement Studio Help
I hope this helps
