AR2300 Receptor 40kHz ~ 3150MHz
AOR
O AR-2300 é uma versão de caixa-preta do AR-5001D, um receptor de comunicações de alto desempenho da AOR. O AR-2300 é ideal para rádio e monitorização do espectro em aplicações comerciais e governamentais de cárie, bem como para uso em serviços de investigação de rádio.
aplicação típica de AR-2300 inclui:
• Detecção de sinal
• busca de sinal no modo de frequência e varredura de memória
• ocupação do espectro e on-the-air de monitoramento
• Verificar a cobertura e campo-força
• Sinais e análise de espectro através e de E / Q opcional com software AR-IQ fornecido.
aplicações detalhadas:
• Monitoramento de determinadas frequências, por exemplo, de armazenamento de 1 a 2000 freqüências, recebendo modos, porta de antena, ajuste do atenuador, um acompanhamento constante de uma freqüência ou a verificação de freqüências selecionadas.
• Pesquisa em uma faixa de freqüência com livre escolha de início e de frequência de parada e passo larguras de 0.001 kHz (1 kHz) para 999,99 kHz.
• Detecção de emissões indesejáveis incluindo as emissões pulsadas.
• A detecção de transmissores não licenciados que comunicam de forma ilegal ou que interferem com a transmissão licenciado.
• Acompanhamento do `s próprios exercícios de rádio em uma banda de serviço e acompanhamento das transmissões selecionados.
•-controlo remoto operação através de um controlador LAN opcional em cheque cobertura e sistemas de monitoramento.
• Computer controlled Black-Box:
All functions of the AR-2300 can be used with lap-top or desk-top PC that runs under Windows XP, Vista and 7. The AR-2300 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, DSC, 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.
• Direct Sampling Architecture (40 kHz to 25 MHz)
The AR-2300 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 dual-channel reception within an IF bandwidth is possible. Thus, triple channels can be monitored simultaneously.
• Analog VIDEO demodulation
Composite video output is provided to monitor FM modulated analogue type wireless security camera or frequency search operation for bug transmitters.
•SD Audio recorder
AR-2300 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 AR-2300 can accommodate up to 23GB 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 AR-2300 as receiver front-end. Between 25MHz to 3GHz, the analogue IF output is correlated within ± 1.5dB 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).
