Yes the Thunderbold truly is plug and play. In holdover of course the Rb will be more stable ...
The RS-232 connection also lets you see if it has achieved GPS lock - you can't tell without something that talks to the RS-232 interface. Dave -----Original Message----- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of David Hilton-Jones Sent: 30 June 2009 13:28 To: time-nuts@febo.com Subject: [time-nuts] (no subject) I am not very much interested in how it is achieved, but wonder if a 10MHz oscillator locked to GPS is now available as "plug&play" rather than needing a lot of time/effort/building. I note the Thunderbolt units available from the Far East on ebay for~£80gbp. Are these really P&P - that is, just connect PSU and aerial and out comes 10MHz locked to GPS? Is it necessary to connect to a computer via the RS232 link, or is that just there if you want to fiddle and be clever? If so, then this may be preferrable to running my rubidium source continuously. What I am interested in is stability, not ultiamte accuracy. As always, sorry for the naivety of the question.
