I'm sorry. I don't understand the statement 'control can control itself'.
I'm not familiar with IQS and a quick google search did not turn up anything immediately. Is your GPIB controller from IQS or is it one of the NI GPIB controllers. If the GPIB controller in the pc is not from NI, then you cannot use the LabVIEW GPIB functions and you need a VISA library from the vendor in order to use the LabVIEW VISA functions. Vendors will often provide a set of LabVIEW functions to be used instead of the LabVIEW GPIB functions.
Can you point me to the IQS web site?

Sorry for my previous message. My question is "Controller can control itself?".
Below is the link to see the IQS instrument that I'm using now.

Thanks, that makes things clearer. As stated in the pdf file, the instrument cannot be controlled externally via GPIB. It is only for controlling other instruments. The software for the IQS 12008 is pc based, correct? The pdf file also mentions that there is a set of DLL functions available to control it. They mention COM which is the old description of ActiveX. LabVIEW is capable of executing ActiveX properties and methods. The pdf file also mentions a LabVIEW demo program with source code is available. I see LabVIEW drivers available as accessories on some of the module pages but did not see a place to download these. I don't know if they are free or need to be purchased but you should be able to contact Exo to get details.
This looks like a pretty nice instrument. I work in telecom right now and will have to keep this in mind.

Hi 120341,
Most of our instrument drivers just use simple VISA read and VISA write functions to communicate with your instruments. The instrument drivers you find online are just subVI's that have VISA commands in them. To merge 2 instrument drivers or change functionality, you would just have to change the command that is being sent to the instrument. Combining instrument drivers is not necessarily possible because some of the instruments use different commands. If there is any way you can describe which functionality you want to add to your driver, we may be able to give you some tips on how to modify that driver.
