labview 7.1 doesn't detect my tektronix TDS 684B scope

[tomberg]

Hi !
Even if GPIB is connected, labview 7.1 doesn't detect my tektronix TDS 684B scope. A window message tells me that "instrument is not connected " !! Why ? IS it a GPIB failure ? I do'nt know, but labview detects all others instruments I connected before and after it!
Thank you !

If other instruments are detected, then the GPIB card is okay. Try switching cables. Sometimes you'll find a bad one. It's more likely a setting on the scope. First, make sure the scope has a unique address (non-zero). Then, check the manual to see if there's a setting on the scope to actually enable GPIB communication. I'm not familiar with this model, but some instruments require you to turn it on or if it supports multiple protocols (i.e. serial, GPIB, ENET), you have to rurn on the one you want to use.

Hi Dennis!
You were true ! It was a problem of GPIB address setting on the scope, but it's now ok!
Thank you!
