old news to some (most?) of you...

[Robert E. Seastrom]

In an effort to get my hands around how to drive the Agilent spectrum
analyzer that I borrowed a week or so ago (not self-explanatory like
my first encounter with an oscilloscope in high school!), I managed to
turn up a pdf of HP Application Note 150 - Spectrum Analysis at
http://dsnra.jpl.nasa.gov/technical/spectrum_analyzer/modulation.pdf
Worthwhile read.
