How to communicate with SCPI using Labview?

[inuyasha84]

Hello.

I want to communicate with SCPI using Labview but I have no idea on how do it. Once I have connected my device to the pc using the ethernet connection how can I send the SCPI commands to the instrument? I tought, but I don't know if I am right, to use the VI patterns; if this could be true, where can I find some infos about the VISA? 

Thank you

What is the instrument (make/model)?

Have you looked for LabVIEW drivers, you may want to search it here.

No unfortunately they are not NI instruments. One is an agilent instrument. I want to start to practice with this one.

Have you checked the link, moderator1983 provided?

Please read carefully:

He was talking about INSTRUMENT drivers, not DEVICE drivers.....

NI has a strict terminology on this:

Device: NI product, most often build into the PC/PXI system, nowadays increasing number of USB and E-Net devices available

Instrument: Any third party boxed instrument, interfaces most often Serial (RS232), USB, GPIB or E-Net.

So instrument driver is exactly what you are looking for. And Agilent provides LV instrument drivers for most devices as also Agilent feels the power of LabVIEW....

Oh well sorry I haven't understood it. Now that is clear I checked and those are the two instruments:

and 

http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=19037

now that I have found them...what else?

Thank you guys for your help

You should be going to start your code...

Eheh no really I have other few questions.

In the Rigol link that I posted I read:

"This instrument driver is NOT supported or maintained by National Instruments.   This driver is maintained and supported by the instrument manufacturer or a third party."

So as suggested I went on the Rigol site 

http://www.rigol.com/support/ivi/more.html

but I haven't found the driver. So how to procede?  The instrument is the Rigol DSA1030A. What is the procedure to communicate with an instrument  of which I don't have the driver?

On the other side about the LeCroy instrument I'm taking some minutes to read how to instal the Plug and Play... I'm talking about this guide:

In your earlier post, you mentioned Agilent...

Rigol hasn't provided LabVIEW drivers for this particular instrument, but IVI drivers are available for C-programming-language interfaces (LabWindows) but you can always convert it to something which is compatible with LabVIEW, check this link.

Hi inuyashi,

when the link provided in the IDN doesn't work you could go the "official" way:

- Open the website of the manufacturer (www.rigol.com)

- Search for your device DSA1030A and open it's product page.

- Nearly all measurement device manufacturers support their devices with additional software: so you would open the tab "Saftwares" on the DSA1030A website.

- Wow: Rigol presents you an IVI driver to download, install, and use...

[inuyasha84]

Yea I'm sorry it was supposed to be the Agilent but actually it is used by another guy so those two are the instruments I can use.

Ok Great! I'll check the  option you suggest me for the Rigol and I'll let you know.

Ty guys
