Is it possible to use one GPIB board to control two separative instruments(such as impedance analyzer)?

[Face]

I am wondering whether is it possible to use one NI-GPIB board to control two instruments?
If not, are there anyway to realize it?
two GPIB board?GPIB switch?
Thanks

I knew that it is possible to connenct two identical instruments by one GPIB board.
But I met the following problem?
I connect two identical oscilloscope to one GPIB board
in one computer,but When I use Visa Find Resources.vi,
It only display one GPIB adress(GPIB0::1)
How can I to distinguish these two oscilloscope?
Do I need use second address?
I am not sure how to configure these?
Thanks!

Yep, you need to set the address for the other instrument. With newer
instruments you can use the buttons on the front panel to set the address.
On older instruments, like the ones I have, you need to set a row of
switches, usually located on the rear panel. Just make sure each
instrument has a uniqu
e address and it should work.
