Re: [time-nuts] Thunderbolt - Hardware Versions - PerformanceDifferneces
I guess it depends on whether you are after a frequency reference or a phase reference. My (commercial) Thunderbolt has no problem delivering 1E-10 or better over 1 second (usually MUCH better). Jitter has never been a problem for me, and I couldn't care less about holdover performance, since I don't run my own cell site. If all you want is a reliable, plug-and-play source of 10 MHz, there are literally no drawbacks to these boxes. They just work, and $200-$250 is a fair price for them. People with Z3801As tend to fiddle with them until the cows come home in my experience, and that's fine if that's what you're into, but... wait, what list is this again? :) -- john, KE5FX -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of [EMAIL PROTECTED] Sent: Thursday, February 15, 2007 7:35 AM To: Discussion of precise time and frequency measurement Subject: [time-nuts] Thunderbolt - Hardware Versions - PerformanceDifferneces I'm lucky enough to own a couple of Thunderbolts as well as some of the different telecom versions and they DO NOT have the same performance. The commercially available Thunderbolt (the one comes in the little red box) has the least favorable performance when compared to the industrial versions. ___ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
Re: [time-nuts] Thunderbolt - Hardware Versions -PerformanceDifferneces
I don't know about everyone else, but I'm willing to wait a while (a long while) if it means we could get them for around $100. I have no actual current need for one, I mostly just wanted one (or more if the price is right) just to tinker with and see how it compares. If he isn't willing to come down on his current price then that is his loss, I could pass on this deal and not loose any sleep over it. The great thing about the cellular industry is they are constantly upgrading their hardware so something else will inevitably come along. :) Yes, I agree too that a few units should ship initially to someone to test out and verify they are working and not fried or damaged. Who knows, maybe after he is not able to sell any more at the current premium price, he would be more willing to just dump the entire surplus cheap to one buyer. I can take freight delivery at the office (Houston, TX), store them in the warehouse, test, and re-ship them out via UPS or USPS. Someone in Arizona would probably be the most ideal, as it would be out of state (no sales tax) but not far to ship.

Re: [time-nuts] Thunderbolt - Hardware Versions -PerformanceDifferneces
I'll be honest -- I'm in the same boat. I'd like to get one, well, because it's there. :-) But I'm in no rush and if waiting a month means I can buy two for $100 instead of one for $200, I'll wait.
