GPIB Communication to Multiple Instruments

[Clecio]

Hi friends:
I'm found a problem when I try to read and write with two different GPIB equipaments simultaneous. The display of the equipament shows an error...
Thanks for your attention.

usually this problem occurs when you have two instruments with the same GPIB address, change one of the addresses on the instrument itself and the problem should go away. be sure to change the address in your code.

Hi Joe:

I verified your suggestion and addresses GPIB are different. Do you have another opinion?

Thanks. Clécio.

What is the type of instrument you are trying to communicate with. have you tried to just communicate with just one. are you sure you are sending the correct commands.

can you post a small version of your code that causes the problem.(ie just the comm part)

Give me this info and I will do what I can to help.
