Lecroy DSO internal control

[anthony wang]

As I know, the new Lecroy DSO 434 is a instruments with Windows XP OS. So we can install labview into the DSO. Now the problem is how to control  the DSO via the insturments internal communication? I searched some information from Lecroy homepage and find the method is using automation API(DCOM?). But the example does not metion how to control the DSO by LV.(only VB VC)

I hope somebody who familiar DCOM and Labview can give us some advise.

about automatic API, pls see:  www.catc.com

If you are talking about using LeCroy X-stream to control the scope, then you just call that ActiveX api from your LabVIEW program. The problem with it is that it uses late binding, so you have to write everything out as calls rather than select properties and methods like you normally would with an ActiveX interface in LabVIEW.

Hey Anthony,

Did you solve this problem? I am having the same one but i'm a bit of a newbie and not too sure what i am doing.

Let me know,

Hello,

Alan from LeCroy Tech Support here....

A few comments...

1. The Automation API is described in the manual http://www.lecroy.com/tm/library/manuals/X-Stream_Scopes/Automation_Manual/Entire_X-Stream_Automatio... The link to www.catc.com is for the protocol analyzer products.

2. If you choose to run LabVIEW on the scope, take care not to impair the performance of the scope application (For example, avoid loops that hog CPU or memory.)

3. Using the lcwave or LeCroy Wave Series driver will be *much* easier than using the automation interface.  You should download the VICP passport from the LeCroy website, and install it on the scope... You'll also need NI-VISA (at least the runtime version...)  

Good luck! Feel free to contact me at 800-553-2769.

Best Regards,

Alan

Hi Alan,

I have downloaded the IVI drivers from the LeCroy website and i have got them up and running on the DSO. I can access the DSO using the loopback adapter 127.0.0.1 and it seems to work ok. The question i have is whether i can use the VISA drivers from the National instruments website. I have installed these but i don't know how to access the DSO through VISA. Any suggestions?

Thanks, Phil.

Hi Phil,

Try either the lcwave or LeCroy Wave Series driver on the www.ni.com/idnet. (These are the same, with the latter being the "project style" driver). These are VISA drivers that NI developed last year and which I have helped to debug and enhance.  Please note that they were not specifically developed for use on the scope, but instead for remote control.  Let me know how you fare... Feel free to contact me at 800-553-2769.

Best Regards,
Alan
