[time-nuts] HP 5372A troubleshooting

Hi all, I have been on a steep learning curve on my new 5372A. It's a lovely instrument but does seem to have a higher degree of trigger jitter than I would expect. Going on previous experience with other unrelated instruments I began by checking the power supplies. (in fact it's hard to go much

Re: [time-nuts] Z3801 misbehaving

Charles, The place isn't out of the way. In fact, it wouldn't surprise me if it got a power interruption sometime. In addition, the temperature isn't stable either. It will be at least a couple of weeks before I am ready to attempt to use it for anything, and then it won't matter so much about

Re: [time-nuts] Z3801 Newbie Question

Dave: Your antenna setup sounds reasonable. You might want to try dropping your elevation mask down to 5 or 10 degrees, as an experiment. Things that cause the sporadic jumps could be certain satellites being added to, or removed from the solution. Also, if there are particular angles/directions

Re: [time-nuts] HP 5372A troubleshooting

Morris, you might want to download the 5371A service manuals which contain schematics. The 5372A being an 'upgraded' version of the 5371A, most of its parts are identical. Look for 05371-90018 (Vol.1) and 05371-90034 (Vol.2). They should be available at www.keysight.com The scan quality is

Re: [time-nuts] Z3801 misbehaving

I added 2 X AA batteries external to the 3801 to the GPS receiver. Will run several years and very easy to replace. Now that doesn't make it instant start but certainly sub hour or less maybe 20 minutes. Good luck. Paul WB8TSL On Fri, Jan 29, 2016 at 8:43 AM, John Green wrote:
