I connected a function generator to my computer using a GPIB cable. And I found the driver for this generator and installed it. Unluckily, this dirver use VISA to control. While I could not find the instrument via LabView , found resources.
I checked this instrument using Measurement &Automation. This instrument is connected to GPIB0, address 10. So I believe the I/O port for this instrument should be GPIB0::10::INSTR. While when I tried to write to this port, it failed.
Since it is connected with GPIB cable, I tried with GPIB method. It works well.
My generator is Ag33120A, my LabView version is 7.0 Express.
Could anyone explain why this happens? Why VISA done not work for this instrument? Thanks very much.
