The AOR AR-Alpha is a new professional grade communications receiver which may be 19-inch rack mounted or used as a desk-top receiver. With continuous coverage from 10 kHz to 3.3 GHz (Cellular Blocked for US consumer version), using wide band receive, advanced DDS and DSP technology, the AR-Alpha delivers a powerful monitoring, searching and recording capability. Fast frequency processing is achieved by means of FFT and signals are visually displayed on the 6.4" TFT LED display both spectrally or as a waterfall function. TV signals can also be displayed (NTSC, PAL). Powerful DSP is employed at both IF and demodulation stages allowing many functions including Digital Filtering, Auto Notch filter, IF Shift, Noise Reduction, Analogue Voice De-scrambler, Tone Elimination, DCS, CTCSS, Level Squelch and Noise Squelch. Modes of reception include: WFM (in stereo selectable de-emphasis), NFM, AM (Synchronous AM, diversity synchronous AM), ISB, RZSSB, USB, LSB, CW, P25, Video (FM, AM NTSC/PAL). Dual communications ports are available on the back panel supporting both RS-232C and USB 2.0 connection. A 12kHz output is also provided for external DRM & SDR reception. I/Q outputs are provided with 1MHz Bandwidth. Input RF performance is provided by 17 high performance input Band Pass Filters and high linearity RF stages. A 10.7MHz 2nd IF stage is used and an innovative ZERO-IF 3rd IF is used for the DSP function. The receiver is referenced to an OCXO (Oven Controlled Crystal Oscillator) or external 10MHz reference. |
