Why can't I find my Wavepro 940 LeCroy scope with Measurement & Automation?

[A. F. van Driel]

Hi All,

I am trying to communicate with Labview 8.2 to my LeCroy Wavepro 940 scope. When I fill the IP address in Measurement & Automation, nothing happens. Bud I am able to ping the scope's IP address and with LeCroy software (ScopeExplorer) I am able to communicate to the scope via Ethernet. However, when I try to esthablish such a connection (TCP/IP) via Meas. & Autom. nothing happens. Can anybody tell me if I forgot sometrhing here? Do I need extra software? I installed VISA 2.6.1.....

Thanks in advance and best regards,

Floris

Hi - Alan from LeCroy Tech Support here.

Measurement and Automation Explorer is designed to include instruments that are VXI-11 or LXI compliant.  The WavePro 940 is not, so you cannot add it to MAX in this way.  Please note that there is no need to include the instrument within MAX in order to use it in LabVIEW. 

Feel free to contact me if you need further assistance!

Best Regards,
Alan

Dear Alan,

Thanks for your help!

I tried to connect Labview directly with the Wavepro 940, without using MAX. Within the Functions Palette of Labview I can select from the lcwpxxx-driver. So I guess the Wavepro driver is installed correctly. But when I open a Front Panel and give as Resource Name "TCPIP::<my IP-address>::1861::SOCKET", nothing happens. In this way it should work, no? Or do I do something wrong here?

Best regards & thanks in advance!!

When you control a network instrument through TCPIP SOCKET interface, every device command must explicitly adds the "termination character" such as line-feed (0x0A).  For example, your must send "*IDN?\n" rathr than "*IDN?".

I have the exact same problem with my Wavepro 940. I can get MAX to see it, but I cannot issue any commands. If there is any way to fix this, please help!
