Spectrum analyzer and Tunable laser GPIB programming

[Complex]

Hi

I connect my tunable laser to my PC and my spectrum analyzer is connected to my tunable laser. Is it possible to write  program while in labview while I want to get data from my spectrum analyzer and simeltenously control my tunable laser?  

Thanks

GPIB control is essentially sequential.  Write to A, then write to B, etc.

Of course it's possible. I would suggest you search for a GPIB tutorial before starting.

In LabVIEW, you would most often be using VISA commands and you merely have to provide a different VISA Resource Name for each instrument - i.e. GPIB0::3::INSTR AND GPIB::4:INSTR where 3 and 4 are the GPIB addresses. You don't even have to type them into the control. You use the control's pull-down menu to select from a list. The list is created when you do a scan for instruments in MAX. This should all be explained in the Getting Started document that comes with the NI GPIB controller.

I am trying to find some related tutorial about VISA function but I can not find. I do not know how to read data from other instrument such as spectrum analyzer.Could you help me?

Thanks

In your other post, I gave a link to the Instrument Driver Network. There is a link there to a getting started with instrument control tutorial. Have you done that?

Hi

Could you send that link to me again, please?

Thanks

Hi 

Now, I can connect my tunable laser to the labview and control it, also I can connect my spectrum analyzer to the labview and read the data from it. My question here is, how I can send data to the tunable laser and read data from spectrum analyzer simultaneously?
