LeCroy WaveRunner 62xi - Resource Name?

[therealkilkenny]

Hi All,

This is doing my head in. I suspect that it is something really simple but i cannot figure it out. I have recently got the above mentioned scope. I would like to use LabVIEW on the scope (i.e. on board rather than remotely) to aquire data and process it. I have to the best of my knowledge installed everything required of me. When i open a blank vi and go to the block diaghram i am able to insert the driver/specific functions for the scope.

The problem is that i do not know what the resource name is to input into initalize.ve (for example). Can anyone help? I cannot find any documentation to help me out.

Thanks,

Phil

Hello Phil,

the resource name is a string like 'ASRL1::INSTR'. You can get those names using MAX. By using MAX you can also create aliases for those cryptic resource names (like COM1 for ASRL1::INSTR)... After creating an alias in MAX you should be able to select this alias in the resource name control too.

Btw. all this is also written in the help for the resource name control!

hi there,

i suppose the device is a GPIB scope. then you have to start MAX (search "Measurement & Automation Explorer" in your Startmenu) and add the device (see help of MAX for more information). then MAX will assign a default ressource name to the device. You can change the ressource name at any time.

but first of all: be sure that your GPIB interface works!

Hi GerdW,

Thanks for that. It hasn't solved my problem though.

What should i see when i go to max? at the moment the only things that i see (under devices and interfaces) is PXI System (Unidentified), Serial & Parallel - COM1, COM2, LPT1. I don't know where it scope is. Is it the PXI system? Do i need to identify it? How do i do that?

Thanks, Phil

Hi Chris,

No, it doesn't have a GPIB connection. (unless there is an internal one???) I am not trying to remotely control the scope. I want to control it on-board.

Any ideas?

Thanks, Phil.

Hi Phil,

as ChrisGer mentioned: you probably want to connect the scope by GPIB. As MAX didn't not show a GPIB card I can only guess: you have no GPIB installed or it's not working properly... When you want to use serial connection you should choose COM1 or COM2.

hi there

- do you use an National Instruments GPIB - Interface?
- make sure you installed the required device drivers (see the hardware section of the system manager of your OS)
- if you have a proper running GPIB interface you'll see a "GPIB" section under "under devices and interfaces" in MAX. there you can add devices connected to that interface

Hi Phil,

could you explain what do mean by 'on-board'?

Running LabView on the scope? The datasheet of the scope mentions several software add-ons, but I doubt you can load LabView onto the scope...

Hi GerdW,

I've got LabVIEW running on the scope (it's got xp running on it) and i want to access the scope hardware through LabVIEW on board. Thus i don't think i should be using GPIB or Serial as that would be remote control. I have installed an IVI driver but i don't know what resource name to use to access the hardware. Is the hardware the unidentified PXI system that is showing up in MAX?

Thanks, Phil

Hi Phil,

I don't think it's the 'unidentified PXI system'. On my computer this is also shown with no hardware connected.

It seems you better ask LeCroy how to communicate with their scope. Some kind of hardware should be available - software add-ons from LeCroy surely are able to talk with the scope...
