[time-nuts] Fwd: Fwd: PicTic Data
Stanley and Nigel, I have received the go ahead to distribute the Small DMTD project files from Bill. It is in the form of a 500k zip so how do we want to play this? For a start, Gmail will not let me send .exe files, even though they are inside a zip file and I'm not putting them into a password encrypted file to circumvent this so I'll send the archive with the extension changed to .xxx. If you don't know how to change that back to .zip may I suggest you contact Mr Gates and tell him that his method of file typing sucks and is a noddy system fit only for Toytown.

Back to me who doesn't have any knowns but lots of guessing. Attached is a run with a box cover over the pictic, run is shorter ~ 800 seconds but the box does look like it helps. I need to do a lot more testing but sometimes I just get excited :-) I imported your .txt file alongside the traces I captured. Assuming it was taken with 1 Hz on both START and STOP, it looks like the attached. You're getting the exact sort of results that I see if I feed both the START and STOP inputs at 1 Hz. My guess is that the onboard oscillator limits the performance in that case, since it has a lot of time to drift during the measurement if the two pulses occur close to 1 second apart. Even the 5370B looks much worse if driven with 1 Hz on both inputs than it does with 1 Hz at START and 10 MHz at STOP. So I think you're basically up and running OK. When I get around to trying a better clock, I'll also go back and see if the 1-pps x2 performance improves. It would be great if the next spin of the board could include sine-to-CMOS shapers for the input channels as well as an external clock input, for people who are working directly with RF signals as opposed to 1-pps. -- john, KE5FX - Original Message From: John Miles jmi...@pop.net To: Discussion of precise time and frequency measurement time-nuts@febo.com Sent: Sat, August 14, 2010 10:19:46 PM Subject: Re: [time-nuts] PicTic Data A few preliminary measurements here (I'm working on getting some software support together): http://www.ke5fx.com/pictic.htm -- john, KE5FX -Original Message- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com]on Behalf Of Stanley Reynolds Sent: Saturday, August 14, 2010 7:12 PM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] PicTic Data My guess as to what the data may indicate is performance of the 10 Mhz 20PPM

Steve, I'm sure there are several folks here with web sites or download areas that could host the files. If no one else raises their hand, I could put them on febo.com.
