[time-nuts] What did I buy? Austron 1210D-03

Hi, I just picked up an Austron 1210D-03 on eBay. It was an impulse purchase based on the apparent condition and the fact that it seems like a nice old clock/reference. I searched for old posts about this unit, found mostly discussion about the manual and battery pack. Hopefully the price I paid i

Re: [time-nuts] What did I buy? Austron 1210D-03

Not sure there is much to say. Its a very nice oven xtal oscillator and divider chain. It has some nice features like slew for the 1pps and would guess it has battery backup. But the question becomes the value? Depends on what you are trying to do. There are numbers of GPS locked references for $12

The manual describes it as a time transfer standard. It is equipped with NiCd batteries to facilitate operation of the unit while in transit, as well as the provision for external DC in. Sent from my iPhone > On May 24, 2015, at 16:35, Dan Watson wrote: > > Hi, > > I just picked up an Austr

That was before my time at Austron. We made lots of those and no one seemed to complain until they broke. Jerry On Sun, May 24, 2015 at 4:35 PM, Dan Watson wrote: > Hi, > > I just picked up an Austron 1210D-03 on eBay. It was an impulse purchase > based on the apparent condition and the fact t

We used them as time transfer standards to sync the clocks at the Titan missile sites to the clock at the host base. The sequence was clock sync at the host base, travel to the site, sync the site clock, return to base and check timing error. If the error exceeded x, repeat until the error was

Re: [time-nuts] What did I buy? Austron 1210D-03

Thanks for the replies. I think this will make a very nice clock for my lab, though before I relegate it to a shelf I plan to replace the battery pack and experiment with the performance. I especially like the features for syncing it precisely to an external source. After a month or two of the OCXO

Sort of a Navy AN/URQ-10A (Frequency Electroncs FE1000Q) and a Systeron Donner 8520 rolled into one. Both are in ARINC outlines and would fill about the same dimensions side-by-side. The only difference would be that the SD also outputs IRIG time codes. Greg __

Re: [time-nuts] What did I buy? Austron 1210D-03

Hi What you bought is a really cool “clock trip” style time transfer standard. You sync it up to the “reference clock” and hop in the car. Drive off to the remote site and use it to adjust the “remote clock” to the correct time. Very useful back in those days, if you needed to keep a bunch of r

Hi Best guess is that you will get down below <1x10^-9 fairly soon. That will let you stay within 100 ns of GPS for a >100 second walk around the block…. It would be unusual if it stayed below 1x10^-11 for any length of time. That would extend your walk time to about three hours. As you take

Well the clock survived Fedex Home Delivery (yuck) in one piece. It's in extremely good shape, just as was shown in the pictures. All the buttons and lights work. At turn on, the 10MHz output was about 350 Hz high, and power draw was 40 Watts. It's now setting at just over 0.1 ppm out after a very
