AR2300 Black
HIGH PERFORMANCE BLACK-BOX RECEIVER
Radio monitoring from 40kHz to 3150MHz
The AR2300 communications receiver from AOR is ideally suited for radio and
spectrum monitoring in various commercial and government applications, as well
as for use in radio investigation services.
The AR2300 offers:
Signal detection
Signal search in frequency and memory scan mode
Spectrum occupancy and on-the-air monitoring
Coverage and field-strength check
Signal and spectrum analysis through optional I/Q software
Applications may include:
.. 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.
.. Unattended long-term monitoring by an internal SD audio recorder or spectrum
recording with optional AR-IQ software for laboratory signal analysis.
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.
Lightweight net-book PC can be used as control head for the AR2300. (PC not
included.)
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.
Technical Features:
Wideband IF output: 45MHz of intermediate frequency (IF) analog output with
15MHz bandwidth is provided for external peripherals when using the AR2300
receiver front-end.
The optional digital I/Q output board with USB2.0 interface is available to
access AR2300’s I/Q data for spectrum/playback/analysis by a PC.
Simulations reception and monitoring: Simultaneous reception on HF (below
25MHz) and VHF-UHF (above 25MHz) frequencies is possible. For frequencies above
25MHz, absolute dual-channel reception within an IF bandwidth is possible. Thus,
up to three channels can be monitored simultaneously.
Analog VIDEO demodulation: Composite video output is provided to monitor FM
modulated analog type wireless security camera or frequency search operation for
bug transmitters.
SD Audio recorder: The AR2300 is capable of recording demodulated audio directly
to a built-in SD media recorder. Compact and readily available, SD memory cards
are immune to vibrations and produce no mechanical noise, unlike motor-driven
media such as tape or discs.
The AR2300 can accommodate up to 32GB SDHC card, allowing up to 480 hours of
total recoding time using PC compatible WAV format. The typical continuous
recording time with a 1GB SD card is about 8 hours. The recording time can be
extended when squelch operation is employed while recording two-way voice
communication.
Optional APCO P-25 Digital Voice Decoder: APCO P-25 Digital Voice Decoder option
is available for the demodulation of project 25 (P25) digital voice
communications which
are quite popular in North America for the government and public safety
communications.
Direct sampling architecture: The AR2300 utilizes outstanding direct sampling
digital architecture for reception below 25MHz. It features a 14 bit 80MS/s
analog-to-digital converter, a high-performance FPGA-based digital
down-converter and DSP-based demodulation circuitry. The direct sampling
architecture offers exceptionally high linearity against input signals.
AR2300 Control Software: The AR2300 control software is a strong companion to
the AR2300 black-box receiver. The software provides powerful control functions
running on an MS Windows PC connected to the AR2300 via USB or an optional LAN.
The software provides a signal overview using a high-speed spectrum or waterfall
display.
Powerful memory channel management features are available to manage and control
up to 2,000 channels allowing direct entry of alphanumeric channel information.
The channel hit-counter
and last event (time and signal level) on each memory channel is available to
monitor the activity and channel coordination.
Optional AR-IQ software: When an optional I/Q interface is installed (factory
option), up to 1 MHz of digital I/Q output can be recorded to the hard drive of
almost any computer operating Windows environment for later playback and
analysis without the loss of quality. This feature allows for unattended
logging, signal classification and signal analysis.
