Example programs for DSO1000 PnP drivers do not work at all with DSO1022A

Hi Complex,

I have found some additional information you about the capabilities of Signal express to acquire data from your machine. If you downloaded the IVI version of the driver on ni.com/idnet you can use the IVI Scope acquire step. What commands are you sending to your machine to retrieve the data?

Hi

Actually, I did not send any command.While I connected DSO to my Laptop, Labview Signal Express automatically opened. I really want to know which and how the commands must be send to get necessary information such as Vp-p or Phase and also the wave form when I am using Labview Signal Express.

Thanks

Masih

Hi Masih,

Are you going ot use Signal Express or LabVIEW? In signal express there are some analysis steps that can be used. The one that has those commands is called Amplitude and Levels. It is under the Time-Domain Measurements group. As far as the pictures that you posted, what was the time increment on the graph from the Instrument?

Yes, I want to use labview. but whenever I connect DSO1022a to my laptop Signal Express will be automatically opened and shows nothing so I confused which one is better for capturing data. the time increment for that figure was 10 ms. 

Thanks

Hi

It seems that signal express is now chosen by the OS as a must open application.

I uninstalled signal express because LabVIEW is much more powerful, but it needs a bit more time to get powerful.

Hi 

Thanks for your noticing. Now base on Oscilloscope Programmer's Guide (DSO1022a), if this command (:MEASure:NPHAse[<source1>][,<source2>]) send to it, it will return the values for phase difference between two channels. I try to send this command using "visa write" and get value for phase using visa "visa read", but the value is not correct and different from what we see on screen. Could you help me what is the solution? 

Thanks
