activex + oscilloscope

[scientist]

I have never used activeX before. I need to read data from a lecroy waverunner scope. I have been advised to use ActiveDSO , a piece of software I downloaded from the lecroy website.

I have opened the activeDSO,an activeX control, in labview. Now I am not sure how to proceed. Can anyone help?

I can't help you specifically with ActiveDSO as when I evaluated the scope I used either the IVI driver from here or the driver from Lecroy's web site and that worked just fine. If you're more comfortable with that sort of driver, you could give it a try (especially since ActiveDSO is marked as only being in Beta release).

In general, to use ActiveX, you have to use methods and properties of the ActiveX control to set and retrieve data. Lecroy's web page says that it ships with examples for use in Excel so that should give you an idea which methods and properties you need to invoke with either the LabVIEW Invoke Node or Property
Node functions. There are numerous examples that use ActiveX for other applications that you might want to refer to in how they're used. Start with the shipping example called Write Table to XL.

I have been using ActiveDSO to control a lecroy scope. Today I started to look at using the put and get panel functions. All that I am getting from the scope is a bunch of garbage characters back. Does anybody know the format to use to get the data?

Alan from LeCroy Tech Support here...

Which scope are you using? In older scopes, panel setup files were not text files, so the "garbage" characters you are seeing could simply be the panel file's contents.

Another question... Why are you using ActiveDSO within LabVIEW?  Using a LabVIEW driver (even if it's created from an IVI driver) should make for easier coding.
