No! :wtf: Selling stuff will get you ostracized! :P :P

Selling is allowed as long as it is done in order to fund another purchase AND as long as the other purchase is done first - then you sell .... maybe.... ;)

HP 8642B is very well boatanchory with 36kg weight. May 3U height not delude you. ???

If we're talking boatanchory but modern signal generators, clearly the 8662A is the one to get. http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1981-02.pdf >:D
It was some groundbreaking specs for its time, I think you can maybe do better for close in phase noise today, but it will be very expensive.
I just have a modern, Agilent-badged 8644B as my only RF signal generator. Pretty darned good specs and cost me only about the same as my vastly inferior 8648B had (which is sitting around with a broken power supply for which replacements seem to go for $300 used on eBay. I should take a look at it again sometime, but I think I found an open transformer winding, and it was a switching supply made by a third party for which no schematic was available.)

Well, then you need one of these Buchla function generators. ;D

Holy hell. :o
And a Uni degree to know how to operate it. :scared:

More knobs than you can shake a stick at alright. But from the looks of it it seams like it works like one of those drum machine sequencers where it just loops around all the time. If it can interpolate between them this would make a sweet reflow oven profile controller.

I also probably should not buy another RF synthesizer, I got 2 already. Tho none of them has a HP badge on it....no no rack is full.
Cubdriver:
Berni, if the rack is full, that's a strong indication that you need another rack, too. >:D >:D
