So your primary interest is the quality of the other guy's signal?

What you want is not possible -- Averaging is working on the IF signal. 
We can choose to always center it, or tune across it. When we tune in 
Tracking Mode, it MUST begin averaging again.

Suggestion: If you have not already done so, assign several Span widths 
and functions to the soft F-keys:  What I find useful are 2 kHz, 10 kHz, 
20 kHz, 60 kHz, 100 kHz, 200 kHz, Peak (Toggle On/Off), Fixed (Toggle 
On/Off). Once you've done this, try looking a bit wider as you tune. You 
may find that you can see things (like stations splattering).

The P3 is a VERY versatile instrument. It's worth studying the Operating 
Manual to see all of the tools available. If you know what you're doing, 
it's possible to make some high precision, calibrated measurements.
