Query more channels by a Rigol Oscilloscope at the same time

[GiuTemp]

Hi folks, I need help to understand what can i do with my oscilloscope.

Initially I wrote the DEMO program, provides with the Oscilloscope. With this I were able to acquire data by a channel.

Now I need to acquire more channels data at the sme time, beacause I have to:

- Trigger the signal;

- compare two different signal from two different circuits that are generated at the same time.

Can I do this? I report my demo.

Thanks for you help

I don't care what your demo VI looks like.

Read the manual.

And I would suggest you take some LabVIEW tutorials and *learn* dataflow programming.

Thanks nyc.

I have just started to study about programming in LabView and I have a lot to do.
But what i wanted to understad is if i can query more channels by an oscilloscope at the same time.

Because if it is not possible, i will change software. I have not so much time to get results 😞

Thanks

Which part of read the manual for the scope do you not understand?

You can query the scope for the second channel after you've read the first. The key is making sure that both channels are acquired at the same time. The software you use is irrelevant to the basic functioning of the instrument.

Your code does not need that silly sequence structure. Get rid of it. What's the make and model of the scope? Have you looked for an existing driver?

[GiuTemp]

Thanks a lot Dennis. My instrument is a RIGOL model DS1054Z. Yes, I've just searched for a driver and it works in sequence. 
But  the purpose of my work is acquire two signal at the same time. I'll take the memory directly by the oscilloscope for post-processing data.

However, Thanks a lot

As long as both channels get triggered at the same time, then you don't have a problem.

If their driver uses a sequence. It is very poor LabVIEW programming.

Gee, he would actually have to read the manual to learn how to do this remotely.

What a concept?
