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 board􀀂with supplied AR-IQ software.

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 band􀀂and monitoring of selected transmissions.

* Remote-controlled operation via an optional LAN controller in coverage check and monitoring systems.

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.

* 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.

* 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.
