I'm sure you're right. The Rb was a hardware option that was added after the original design so I wasn't paying much attention. I thought the chassis was different but may have just been longer than the stock 10.5 version? That chassis design was an experiment where we had an industrial design house create the basic shape and characteristics (extruded aluminum front, beveled key cutouts, etc) and then adapted it to a bunch of designs so it is hard to remember which was which.

I honestly thought we just bolted it in the 1U chassis. I know earlier Datum units with the larger FRS Rbs went into 2U chassis.

As for the reboot, probably depends on where you are probing :-) My proto unit from 1996 is still happily ticking along on my bench in the lab with an MTI oven that still has tuning range. -----Original Message----- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of Julien Goodwin Sent: Tuesday, June 29, 2010 4:27 AM To: Discussion of precise time and frequency measurement Subject: [time-nuts] Datum TS-2100 Rubidium On 28/06/10 21:36, Julien Goodwin wrote: > Up next is to convert the darn thing to Rubidium, like it was meant to > be when I purchased it (insert rant here). OK so the pinout vaguely matches, the TS-2100 is *very* twitchy on the alarm circuits, even a 1Mohm scope (well, it's 1M in theory, cheap Rigol[1]) tripped it to reboot a few times. But where in the world are you supposed to *put* the darn LPRO oscillator, it's too tall to fit above the board, and there doesn't look to be enough room between the back of the front panel and the main board. I'm also not sure about the power supply thing, seeing only the single post to time-nuts about it. I'd love photos, but I'd assume that most people that have one it sits in a rack running. Thanks, Julien 1: Actually 'tis one of the 50Mhz units "hacked" to 100Mhz operation, a very nice Tek 11k analog scope was reserved, but the seller appears to not want my business going silent after several prods. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
