Hmm, no, according to the 5342A manual, it uses CR+LF termination, so the normal query.exe utility should work. It must be a triggering issue.
Try the command query 2 "AUSR4T2ST1" 500 AU = auto frequency mode select (as opposed to M=manual) SR4 = 10 Hz resolution T2 = fast sample (no delay) ST1 = output only when addressed That's similar to Example 2 on page 3-25 of the manual, which doesn't rely on the 'trg 702' statement in the first example. Either T0 or T2 mode (page 3-23) should work with query.exe; T1 may not. Also try it with ST1 versus ST2 in the last three characters of the command, to see if that makes a difference. -- john, KE5FX > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of John Miles > Sent: Wednesday, January 30, 2008 5:38 PM > To: Discussion of precise time and frequency measurement > Subject: Re: [time-nuts] HP5342A GPIB programming > > > Sounds like a handshaking issue.
