I have 2 parts units got cheap , and then bought one that was spouse to work , well partially .
With the 3 I have all options , including a riser board bolted in the 3 unit .
I have seen lots of these , mostly on line and most are missing a cover in the top right rear , seem to be a common part left out during ? whatever ?
Oh and have not seen you around another hang-out for some time , hope all is ok ?

There is a hand full of people over there who really don't like to see a woman who knows more electronics than they do. Then you have K6bbC; he single handily managed make that place one of the least desirable places on the Net.

Sorry to see a good resource be lost to that site .
I haven't been hanging out here as much , so just having seen ya around .
It's too bad , I know the media in general is polarizing the masses , but there also seems to be more illness , hate going around .
To get back on topic , kinda - the thread title - spec. analyzer , I followed a Google search on the HP 8650B .
My newest one came from someone on the ZED , and did not have all functions , then more quit after looking into it more .
I've read that if in storage sitting on the feet on back / front facing up , that some lube ? in the main oscillator flows over time and you can loose the signal , have you come across this ?
   
rob.manderson:
I'm guessing you mean the 8640B?  If so, yes, it's not good to store them on their front or back because the cavity lube flows.  I haven't seen it myself but I understand it can take months(!!!) to get back to normal.

Otherwise, a fine signal generator and you can have mine when you pry it from my cold dead hands!  :-DD
