help w 3495A scanner

Question asked by VRFuser on Mar 18, 2000
Hello Jim,

Be sure to check the Enter and Output terminators for instruments of that
vintage.   Invoke "Advanced IO Config" for the instrument in instrument
manager and insure that you use carriage return followed by linefeed
(
) for both output and enter.  That will normally satisfy the instrument
for those bus transactions and the bus analyzer should then show the
transaction list.
