I/O Errors

Question asked by VRFuser on Jan 25, 1998
Hi Iain,

Don't know your type of instrument, but had similair experience with
a very old spectrum analyser.
In my case it turned out that this analyser was very slow with
presenting replies on the GPIB. I had to set the timeout to a very
high value, and to rearange my command structure a little (the
structure was simple, as in your case).
Hope this helps you.
