[Test-Equipment] Calibrating FM modulation Monitors with BesselFunction

[Eric Lemmon]

Another excellent article is found here:
<www.repeater-builder.com/ge/datafile-bulletin/df-10008-05.pdf>
This is GE Datafile Bulletin 10008-5, entitled, "Measuring FM Deviation by
the Bessel Null Method."  There are many other very useful bulletins on the
GE Mastr Index.

A Tektronix booklet on spectrum analysis use
discusses using the second carrier null
of with a 13.5858 kHz tone to define 75 kHz deviation.

One source of the file is:

See page 23.

there may be other sources for this booklet.
