[time-nuts] Interesting PU observation

My Z3801A has been running for a few weeks now and the PU has slowly gotten to about 2.4uS and held there for the past few days. I just looked at the stats display and see that in the past six hours, the PU has dropped in large steps down to 800nS. Wow, that is impressive. What would make such a

Re: [time-nuts] Conical inductors

Just so you know, Colicraft makes them too. http://www.coilcraft.com/bcl-s.cfm#table Probably quite a bit cheaper than Piconics and they are available either with flying leads or surface mount. I don't believe they use any core material but the specifications look like they would be suitable for

Re: [time-nuts] Acitve GPS antenna biasing

For a broad band, surface mount biasing inductor I use the Minicircuits TCCH-80. The pin 1 goes on the microstripline. The pin out has to be looked at carefully because the connections as viewed from the top and bottom do not connect straight through the multi layer ceramic base. John

[time-nuts] Trimble DSPMon Software

Hi All Does anybody have any experience of the Trimble DSPMon software? I'm running some initial tests on a pair of Mini-T GPS modules and DSPMon is the recommended software. However, I've tried two versions, including 1.53 which seems to be the latest, and neither will talk to the

Nigel, I don't have that feature. Maybe a difference between the two versions. How about emailing that one over to me. 1.46 found the Res-T with out any help from me as soon as I told it what Com port it was hooked up to, 8 in this case. Had At 02:52 PM 10/9/2009, you wrote: In a

[time-nuts] hp10811 OCXO shipping jolt/drop survival?

HI all , I had a 5370 A shipped to me that suffered enough of a drop/roll to break a handle and bend the chassis such that the bottom panel had to be modified to get it back on. When I connected the timebase output to the start input the frequency display is 10.000xx with the last two
