[time-nuts] Examples of traditional phase noise analyzers

[Bob kb8tq]

Hi

The “original reference” for doing phase noise was a Fluke app note 
published back in the late 60’s / early 70’s. Pretty much everybody
used it as a starting point when setting up measurements. Just why
Fluke came out with the information before HP or GR is one of 
life’s mysteries ….

A quick Google search does not turn up a copy. I’m pretty sure *somebody*
must have a copy on their web site. 

Past that, the manuals and papers associated with the HP 3048 would
be a good place to look.
