I do not see the waveform correctly in the VI

[Dennis_Knutson]

With the waveform actually visible on the scope, I'm not sure what could be wrong. The VI is simply doing an Initiate and a Fetch. Is there any error indicated?

[perikillo]

Apparently there is no error. When I click Run, the VI doesn't tell any error. I only see the mentioned horizontal line.

[Dennis_Knutson]

By default, the fetch is done on only channel 1. Are you sure this is the channel you have connected to the signal?

[perikillo]

Yes, I'm sufre of that. I am using the channel 1.

I'm running out of ideas. Instead of using the autoset function, perhaps you will have better luck specifying the horizontal, vertical, and trigger parameters.

[perikillo]

Do you mean use the autoset of the oscilloscope or any autoset in labview (I don't know any autoset function in the labview). And in the other hand, can you tell me more about how to specify the horizontal, vertical, and trigger parameters,please?

[Dennis_Knutson]

Yes, try using the scope without calling the scope autoset function.

There are functions in the driver to specifically set the vertical, horizontal, etc. Just like manually setting the parameters with the knobs on the front panel.

[perikillo]

Do you refer to the autoset in the scope? I don't use it, I just turn on the scope and connect the cable from generator and the usb cable.

I see in the driver folder called "Public" some VIs called Configure Trigger ... I guess you refer to these VIs. I didn't know that these VIs modify the behavior of the principal example. Is this so?

[Dennis_Knutson]

Every time you ran the top level example you did an autoset. Did you even look at the block diagram?

You have an entire palette of scope functions - Instrument I/O>Instrument Drivers>Rigol DS1000 Series. All of those functions are for you to write your own code to control the scope. The examples are just that - a starting place. Since the example you are using relies on the autoset function, it's not even a very good example, imho. Try the Acquire Multiple Waveforms and see how the vertical and horizontal are set. Go to the main instrument driver network page and review the information on drivers, especially on how to use one.

[perikillo]

Ok, I will try it without the block called "autosetup.vi" and I'll post the result.
