Bill, Believe it or not, the HP 8640B is one of the cleanest, as far as signal goes, that you can get, and you can get an option that will take it to 1 GHz, if I remember. You can pick these up pretty cheap, but they have a problem with some plastic gears going out on the tuning assembly. These are old too, but you can find junkers for parts.
>From a report I read on signal purity once, the next best for these oldies, was a Boonton 102, which outperformed a lot of modern generators concerning purity. However, it won't go to 1 GHz, I don't think, and I don't think there's an option for it. If you're not too worried about extra clean signal purity, there are several others, including ones made by Fluke, and or Wavetek. Don't get me wrong, these not are cheap junk, it's just they didn't show as clean an output as the HP and Boonton above. Without knowing any other features you want, it's hard to tell you anymore than these recommendations. I forget where I read the test done on several of these RF generators, but it's on a website, and others on here may know of the tests I'm speaking of. Also, on the HP 8640B, one could get those plastic gears recut in brass, if they did break, and they would last forever.

Oh yeah under $1000 or so. I found a real nice one from holzworth but it is about $5k which is a bit rich for me. I have seen. Various hp synthesizer but digging through the specs and the number soup is tough for a non-electronics guy. > >Tia, > >Doc > >Sent from my iPhone >_______________________________________________ >time-nuts mailing list -- [email protected] >To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts >and follow the instructions there. > >__________ Information from ESET Smart Security, version of virus signature database 5851 (20110206) __________ > >The message was checked by ESET Smart Security. > >http://www.eset.com _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
