Spectrum Analyzer vs. Field Strength Analyzer

[J Autt]

I am looking for a handheld Spectrum Analyzer BK2650 (Link1 below) or
Field Strength Analyzer Protek 3290 (Link2). The problem is that I
cannot see the major differences between them, yet there's a major
price difference of $1000-2000. Can anyone tell me what the major
differences between a spectrum analyzer and Field Strength Analyzer?
Is it in demodulation ways, sweep speed, display freq span, or some
extra stuff that I do not need as an amateur/electronics hobbyist?
Thanks.

Spectrum Analyzer
An instrument which displays the frequency spectrum of an input signal,
usually amplitude vertical vs. frequency horizontal.

Field Strength Analyzer
Practical field-strength measurements call for an analyzer that is portable
yet powerful. The model 3290 RF Field Strength Analyzer from PROTEK Test and
Measurement (Allendale, NJ) is a handheld instrument that contains not only
a full-featured spectrum analyzer capable of measurements from 100 kHz to
2.9 GHz, but also a sensitive frequency counter, a host of demodulators, and
the choice of operating on batteries, AC, or vehicle DC power.

Field-strength measurements call for an analyzer that is portable
and *sensitive* (NOT "powerful"; this is not a transmitter for moon
bounce!).

By "powerful" in advertising literature they probably mean lots of
filtering/display options, connectivity, DSP functionality, that kind
of thing.
