[Elecraft] P3 as a phase noise measurement tool

[Dave (NK7Z)]

Hi,

I am contemplating practicing some phase noise measurements using a P3. 
If I correctly understand the measurement, (which I may not), I should 
express the result, using db down from peak, so many Hz away from peak, 
using a 1 Hz width.

First question; is the above correct?

Second question; (amusing Q1 is correct), what is the pixel width of the 
P3, and can I just divide that width by total frequency spread shown on 
the P3, and assume that number I get is correct for width per pixel in Hz?

Third question, (assuming Q2 is correct), once I get a number from 
question 2, can I then just divide that result by X, where X is selected 
to bring the width of measurement to 1 Hz?

Thanks in advance for any help in this...
