[time-nuts] Fw: Austron 2100F
If I divide one of the phase corrected outputs to PPS and use it instead of a gps receiver to discipline the input reference crystal oscillator would this system have any advantage over the corrected outputs? I did find a web reference where NASA was using a 2100 receiver to discipline a Austron 2010B reference as part of a triple redundant clock (GPS, Loran-C, and Cesium beam). http://tycho.usno.navy.mil/ptti/1993/Vol%2025_02.pdf Stanley - Original Message From: Dan Rae <[EMAIL PROTECTED]> To: Stanley Reynolds <[EMAIL PROTECTED]> Sent: Wednesday, June 11, 2008 12:23:35 PM Subject: Re: [time-nuts] Austron 2100F Stanley Reynolds wrote: > > Yes, would like to know about the phase corrected outputs, any specs, > are they close to the accuracy of the Loran signal it's self ? Nothing claimed in the specs. It just says: "Square wave output, will drive 1 standard TTL load" for both 1 and 10 MHz. Long term, I'm guessing it approaches that of the Loran signal. It looks like the no suffix version is a bit different from the others. Dan __ Do You Yahoo!? Tired of spam? Yahoo!

Yes, would like to know about the phase corrected outputs, any specs, are they close to the accuracy of the Loran signal it's self ? > the chart output looks like it outputs a voltage between 0-15 volts at the > start with it tending toward the millivolts volts as it continues In my 2100 the "Phase Record" output at the rear outputs from 0 to 1 Volt representing an accumulated phase shift of 1 or 10 µsecs at full scale. This sounds unlike yours. Not sure yet as it is stable at .5xx volts now it maybe the same as yours but mine has a problem ? My location Birmingham Al is not close to any station and I may have interference in my neighborhood. I 'm using the 7980 chain now but have received the great lakes chain before. The Grangeville LA station is the strongest here. It may help to connect a scope and look at my signals.
