BNC is definitely not an option. My "standard" connector for this project is a TNC connector. It's rated to 8 GHz and many adapter are available for cheap. The N connector might be an option (I can propose the PCB with a Type-N) but as you said, it will require another front panel. Keep in mind that Agilent is selling this front panel for $199 ! I think this doesn't worth that price. -----Message d'origine----- De : time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] De la part de Rich Stolte Envoyé : jeudi 25 mars 2010 21:12 À : time-nuts@febo.com Objet : [time-nuts] FW: Re: Low-Cost 6+ GHz Prescaler board for N connector would be preferable if space would accomidate the cutout being drilled to a larger size. If not, the front panel from the 5 GHZ /12 GHz counter is available from Agilent. They did not use a BNC connector past 3 GHz and I don't think you want to either. As far as the specification tradeoffs, I think you should try to mirror Agilent's specs as closely as possible for their 5 GHz opton <http://www.home.agilent.com/agilent/product.jspx?cc=US&lc=eng&nid=-53690243 8.536907575&pageMode=OV> http://www.home.agilent.com/agilent/product.jspx?cc=US&lc=eng&nid=-536902438 .536907575&pageMode=OV Anything that does not meet Agilent's spec will cause calibration problems for anyone who wants to send it off to a commercial calibration lab unless they are given very specific instructions which might be hard to do years in the future when the specs to your board have been forgotten and mislaid. Pricing would depend on a few factors, not the least of which would be your fixed cost, and how much work / cost are involved in making the front panel connector work. I would say a range from $250 each to $1000 each wouldn't be unreasonable. If you hit the low end of that range, I would be interested in talking about buying a quantity of them from you to resell. At the high end of that range, you can probably find a few buyers if you work hard at marketing, but definitely count me out. Right now, it is also hard to find option 010 oven timebase for these counters. I wonder if you or someone else on this list has any insight about the possibility of retrofitting one of the older ubiquitous oven oscillators, or possibly even an lpro? _______________________________________________ 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.
