So far I'm quite happy with the Temex LPFRS-01 I purchased from ebay.
The unit I purchased uses a single 24 volt supply and came with a heat sink and a circut board with a trim pot to fine tune the frequency. The connector on the board is a standard IDC style and the connectors on actual unit are also standard. The unit I purchased also appears to meet the published short term stability spec of 3 x 10-12 / 100 seconds for the "standard" unit. ----- Original Message ---- From: Joseph Gray <jg...@zianet.com> To: Discussion of precise time and frequency measurement <time-nuts@febo.com> Sent: Wed, April 6, 2011 8:46:15 AM Subject: Re: [time-nuts] Portable standard As usual, lots of good replies and more links to things for me to read :-) On the topic of rubidiums, I see three different brands on ebay. The FE units sell for much more. What are the differences between the three brands? Is the FE brand worth the price? Considering that these are all used units, how long before the rubidium lamp is dead? What about powering these things? Any precautions?
