AR2300
BLACK-BOX
PC Control All-Mode
High-Performance Communications Receiver
40kHz to 3.15GHz
AOR, LTD.
The future of radio monitoring.
The AR2300 is a Black-Box version of the AR5001D, a high-performance
communications receiver from AOR. The AR2300 is ideally suited for radio and
spectrum monitoring in various commercial and government applications, as well as for
use in radio investigation services.
„ Super Wide Range
Continuous
frequency coverage: 40 kHz to 3.15 GHz in 1 Hz step with 1ppm
frequency accuracy. (Frequency accuracy can be optimized to 0.01ppm with
an optional GPS receiver,)
„ Multi-Mode reception
High performance digital signal processing circuitry offers variety of reception
modes as well as decoding options. Receiving mode includes USB/LSB, CW,
AM, SAM, FM, Wide FM and FM stereo. The decoding modes include CTCSS,
DCS, DTMF and APCO P-25 by an optional P-25 decoder.
„ High-Performance analog front-end
The RF front-end is carefully designed by CAD to obtain optimum performance
across the entire frequency range of 40kHz to 3.15GHz.
AR5001D Receiver
Typical application of AR2300 includes:
„
„
„
„
„
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 an optional I/Q boardwith supplied AR-IQ
software.
„ Digital Signal Processing
The 45.05MHz IF signal is processed by the independent signal processor for
signal demodulation and recovery. No AGC circuitry is used in the analog
stage to ensure accurate level reading as well as to offer IF output signal level
linearity against RF input signal.
„ Direct Sampling Architecture (40 kHz to 25 MHz)
The AR2300 employs 14bit/65Ms/s direct sampling receiver architecture for
VLF, LF and HF band. The direct sampling architecture assures high IMD and
IP3 characteristics.
„ 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.
„Simulations reception and monitoring
Simultaneous reception on HF (below 25MHz) and VHF-UHF (above 25MHz)
frequencies are possible. For the frequencies above 25MHz, absolute dualchannel reception within an IF bandwidth is possible. Thus, triple channels can
be monitored simultaneously.
„ Analogue VIDEO demodulation
Composite video output is provided to monitor FM modulated analogue type
wireless security camera or frequency search operation for bug transmitters.
Detailed applications:
„Monitoring of given frequencies, e.g. storage of 1 to 2000 frequencies,
receiving modes, antenna port, attenuator settings, constant monitoring of one
frequency or scanning of selected frequencies.
„Searching in a frequency range with freely selectable start and stop frequency
and step widths of 0.001 kHz (1Hz) to 999.99 kHz.
„ Detection of undesired emissions including pulsed emissions.
„ Detection of unlicensed transmitters communicating illegally or interfering with
licensed transmission.
„ Protection against tapping by detecting miniature transmitters (bugs)
„ Monitoring of one's own radio exercises in a service bandand monitoring of
selected transmissions.
„ Remote-controlled operation via an optional LAN controller in coverage check
and monitoring systems.
„ SD Audio recorder
AR2300 is capable of recording demodulated audio directly to the built-in SD
media recorder. Compact and readily available, SD memory card 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 240
hours of total recoding time using PC compatible WAV format. The typical
continuous recording time with 1GB SD card is about 8 hours. The recording
time can be extended when squelch operation is employed.
„ Wideband and high-performance IF output
45.05MHz of intermediate frequency (IF) analogue output with 15MHz
bandwidth is provided for the external peripherals when use AR2300 as
receiver front-end. Between 25MHz to 3GHz, the analog IF output is correlated
within r1.5dB to the antenna input by accurate signal source with traceability,
thus accurate signal monitoring or measurement is possible with appropriate
measurement antennas.
The graph shows typical IF output characteristics. (Absolute level difference
between Input level versus IF output level. )
Technical Features:
„ Computer controlled Black-Box
All functions of the AR2300 can be used with lap-top or desk-top PC that runs under
Windows XP, Vista and 7. 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. )
„ AF-IQ Output
12kHz IF output is provided for the PC sound card based SDR (software
defined radio) for signal demodulation by the PC. Typical application include
the reception of DRM (Digital Radio Mondiale) broadcasts on HF frequencies.
Options:
Software:
„ Accurate reference frequency
The AR2300 is capable of using GPS pulse signal for the accurate time base
for the local oscillator circuit. 0.01ppm frequency accuracy for the 10MHz
internal master oscillator is obtained when synchronized to the GPS signal
source. The optional digital I/Q output board is capable of acquiring GPS
data for time-stamping on digital I/Q data.
„Control Software (Standard Accessory)
The AR2300 control software is a strong companion of the AR2300 black-box receiver.
The software provides powerful control function running on an MS Windows PC connected to he AR2300 via USB or an optional LAN. The software provides a signal overview using a high-speed spectrum or waterfall display.
Optional GPS Receiver.
Third party product. (Connect to accessory jack.)
„ Digital I/Q board and PC software
When an optional I/Q interface board is installed, up to 1MHz of digital I/Q
output can be recorded to the hard drive of computers operating under Windows environment for later playback and analysis without any loss of quality.
This feature allows for unattended logging, signal classification and signal
analysis. PC Control software for Windows XP, Vista and 7 is supplied with the
board.
Powerful memory channel management features are available to manage and control
2,000 channelsallowing to enter alphanumeric channel information. The channel hitcounter and last event (time and signal level) on each memory channel is available to
monitor the activity and channel coordination. Plug-in to the AR2300
Approx. size 100 x 50mm
„ APCO P-25 Digital Voice Decoder
APCO P-25 Digital Voice Decoder option is available for the demodulation of
project 25 (P25) digital voice communication which are popular in North
America for the government and public safety communications.
Plug-in to the AR2300
Approx. size 125 x 50mm
„ AR-IQ Software (Supplied with digital I/Q board)
When an optional digital I/Q board is installed, the I/Q output can be recorded to the
hard drive of almost any computers operating under Windows environment for later
playback and analysis without any loss of quality. This feature allows for unattended
logging, signal classification and signal analysis . The AR-IQ software has been developed exclusively for AR2300 by Microtelecom of Udine, ITALY.
