[time-nuts] HP 10811A vs 10811-60111

[David Kirkby]

Can anyone tell me the difference between the two above oscillators? I 
have the manual for the 97page manual (page 2 is upside down), but it 
does not mention the latter.

However, I think I have seen a small couple of page document somewhere 
which listed the 10811-60111 as having no specification for phase noise, 
and so therefore not an ideal choice for a low phase noise oscillator. 
One might as well start with something that is specified for a low phase 
noise.

I can't however now find the exact spec of the 10811-60111. Can anyone 
give me it?

I won an auction for a 10811A on eBay and the seller said I could have a 
10811-60111 for the same price if I wanted it too. I said no, I wanted 
the 10811A, but he has sent me the  10811-60111 instead.

Is the 10811-60111 inferior? How does it differ from the 10811A?
