FEATURES
The
300JA
is the first
hand held
frequencycounterto combinethe computing
power
of a microprocessor
with
the
OElO
high speedcounter
Ie
to provide
unparalleled countingcapabilities. The:nxJA can captureoff-the-air signal
frequencies completely withoutoperator intervention-and to record the
result
in
internal
memory .
The micro proces sor
digitally
fil m the RFsignal frequencies and reducesspurious
counting.
All of this is done without relyingon the signal strength to exceedsome
arbitrary
1eveI, ensuringreliab le perform ancein today s densesignal enviroerrents.

only whentheseconditionsare satisfied will the count
be presented to the user.
Internal memory allowsthe 300JA
to

bXally
unattended operation• the XOOA can
be turned on and will
siently record
the frequency ci any nearby radio lr.lIfic At
any time later, the 300)A 's memoriescan be recalledto check the resultsoi an
extended monitoring period.
