virtualbench oscilloscope programming with labVIEW

[Edmond_Dantes]

Hello!

I'm making a vi to control VirtualBench FGEN and MSO.

When I run the vi using the highlight appears a green arrow on the icon representing the MSO_read function, and the application stops without completing commands.

I tried to run an example application downloaded from the official NI site, but this problem remains.

Sorry, but I cannot find anything in the help.

There is a dedicated board for VirtualBench - http://forums.ni.com/t5/VirtualBench/bd-p/340

You'll have better luck posting there instead of instrument control. You can click on Options and request the moderator to move your question there.

The MSO Read VI will block until the acquisition completes.

Check that you are configuring your trigger condition in such a way that the condition can be met. Alternatively, you can set the 'Auto Trigger' input on the MSO Run VI to 'true'; this will cause the MSO to trigger automatically if the trigger condition is not met within the timeout period.

Thank you very much, Brandon!

I'll try by changing trigger settings.

Brandon,

I hate to drag up an old thread, but my situation fits this thread perfectly. 

Is there a way to adjust the timeout period? IF so, how?

Thanks,
Joe

Hi Joe :0)

You can indirectly. The MSU Run VI documentation shows the formula VirtualBenches uses to set the auto-trigger timeout:

The timeout period is the trigger delay plus the greater of pretrigger time * 2, or 0.5 seconds.

JoeFriedchicken,

Thank you for pointing that out. I guess I just missed that.
