[Hallicrafters] Signal generators

Thu Nov 24 09:56:00 EST 2011

Greg, Ive an A version here that I cant even give away.Besides the 
thumbwheel frequency entry the phase noise makes MDS measurements impossible 
on anything better than a S-38 on 10M!
Besides they weigh a ton.

The 8656B is very good (the A version is noisy) and the 8657 is better; Ive 
used those at work a lot. After thet it gets real expensive.

There are also several HP service monitors hitting the market that have a 
lot of capability for the price.

If you need lower frequency capability then the HP 11710B is a natural; I 
use one on the 8640B for HRO-500 and LF-10 work.
