New AOR AR2300 TSCM receiver
"AOR AR2300: 40kHz-3150MHz, Digitally processed Professional Grade,
Black-Box"

Applications:
􀂄 Monitoring and storage of up to 2000 frequencies, receiving
modes, antenna port, attenuator settings, constant monitoring of
one frequency or scanning of selected frequencies.
􀂄 Searching a frequency range with freely selectable start and
stop frequencies and step widths of 0.01 kHz (10Hz) to 999.99 kHz.
􀂄 Detection of undesired emissions including pulsed emissions.
􀂄 Detection of unlicensed transmitters communicating illegally or
interfering with licensed transmission.
􀂄 Protection against eavesdropping by detecting miniature
transmitters (bugs)
􀂄 Monitoring of one's own radio transmissions in a service band
and monitoring of selected transmissions.
􀂄 Remote-controlled operation via an optional LAN controller.
Technical Features:
􀂄 Computer controlled Black-Box
All functions of the AR2300 can be used with a lap-top or desktop
PC that runs under Windows XP or higher OS. The
AR2300 can be controlled remotely through an optional LAN
controller.
􀂄 Digital signal processing
45MHz of the 3rd intermediate frequency is directly digitized for
digital signal processing for demodulation and spectrum display
by a PC. No automatic gain control (AGC) is employed in the
analog circuitry to allow accurate level monitoring across the IF
bandwidth.
􀂄 High performance analog front-end
The analog RF front-end is carefully designed and by CAD to
gain optimum performance across the entire receiving
frequency range of 40KHz to 3150MHz.
􀂄 Direct digital sampling
The HF stage (40kHz to 25MHz) employs direct digital sampling
architecture that offers exceptional linearity across the band.
􀂄 Direct digital synthesizer (DDS) local oscillator
Direct digital synthesizer is employed for the 1st local oscillator
that ensures fast frequency switching for memory channel
scanning and frequency band search operation.
􀂄 Accurate reference frequency
The AR2300 is capable of using a GPS pulse signal for an
accurate time base for the local oscillator circuit. 0.01ppm
frequency accuracy for the 10MHz internal master oscillator is
obtained when synchronized to a GPS signal source. The
optional digital I/Q output board is capable of acquiring GPS
data for time-stamping digital I/Q data.
