trigger oscilloscope lt354m

[giacomourbini]

Is there any other method to dected the trigger?

[Dennis_Knutson]

I'm guessing that you haven't tried the suggested method. Explain why?

[giacomourbini]

Because I don't know how to do this. And actually I still don't find it. Can you help me more?

[Dennis_Knutson]

It's really simple. Do a VISA Write of OPC? and then do a VISA Read. Both would be in loop. Exit the loop when the read says the operation is completed.

I don't know why you can't find it in the manual. You have not said if you are using the manual that I gave a link to. It took me only seconds to find the command in there.

[giacomourbini]

No, I don't use the manual you send me. Anyway I'm not sure to explain mysel well:

I have an oscilloscope which triggers a number N of times and every times it triggers I have to save the data into files. When it triggers for the last time I have to save the data and the stop the .vi.

If you can help me I'll be very grateful to you

Unless you read the manual and understand how to command the scope, you will get nowhere.

[giacomourbini]

But I read the manual. But I didn't find anything on how to recognize when the trigger comes

I have helped you. There are some things you have to do yourself. I don't have the instrument and if I did, I have no way to reproduce your experiment. As a final couple of tips, go into MAX and execute the query there and see what comes back. Also look at the examples for the instrument. I would suspect that the OPC? is being used in at least one example. Use the text search in LabVIEW to look for it.

[giacomourbini]

I don't want that you do the work for me. But I am not an expert in Labview and I don't know how to use this *OPC? query. Anyway I will try to find a way myself.

[Dennis_Knutson]

It's not really a question of LabVIEW. It's understanding instrument communication. The VISA test panel in MAX is not using LabVIEW.
