Using two 3561A signal analyzer simultaneously

[Nghtcrwlr]

Hi

I have two 3561A signal analyzers. I can read and write one analyzer at a time.

Now i would like to read 2 outputs from 2 different sources on these two analyzers.  Is it possible to acquire the data from these 2 signal analyzer simultaneously.

I think these analyzers have a fixed addrerss as 11. So when i run 2 VIs at the same time for the two sources, will there be an error?

Is it possible to change the address of the device manually??

Within the Manuel it should be descriped how to change the GPIB adress, and yes it should be possible.

Okay I found out the new address for the second device and now am able to write in to it and read. But just after running the vi an error message comes. So each time t his error message comes and so am not able to move further....

Device one have address 11 and the device 2 have address 10. I found these addresses from Measurement and Automation explorer.

WHat could be th reason?

Hi Nghtcrwlr,

can you please show the program you currently use?

I think some clarification is needed. You can probably simultaneously trigger both instrument so they acquire at the same time but GPIB communication is essentially sequential in nature so don't just place code in parallel. That probably will not work.

Heyy all

As Dennis said, its not possible to run the 2 analyzer parallely. I inserted them in a sequence structure and now it works. The only thing is that first analyzer does the reading , takes around 8 secs and then the second one starts...

thankss
