Instrument not found

Windows XP SP3. and ni488.2 v.2.6 seems does not maintain older Agilent spectrum analizers. ;(

Hi

after searching a bit more I also found the 2.6 driver.

I don't believe that older agilent instruments  are not supported anymore.

Did you again try with slow bustiming?

I also mostly disable auto polling but there should be no srq in finding an instrument.

Of course I've tried to slow bus-timing. And even disabled autopolling. On Friday I'll try to replace USB-HS and analizer and find which of them are broken. At workplace USB-HS functioning with RS ESI26 very well.

Good luck

You seem right. This looks like a broken device.

Today tried my GPIB-HS at work and found that all works good. Now I'm finding another Agilent analizer to check if the my one is broken.

Just tried to connect another Agilent 8563ec spectrum analizer. With the old one there were 997 instruments found from 0 to 996 with Primary addresses =0. With the new one 13 devices were found with primary addresses from 18 to 30. I've tried all buss-timing values.

Seems it is a driver error.
