FEATURES, FUNCTIONS AND SPECIFICATIONS:
AR5700D is a high-end table-top receiver with wide band coverage between 9kHz and 3.7GHz. It supports a variety of digital, as well as analogue modes. Some of its outstanding features are:
• Digital signal processing: Input signals after the 45.05MHz IF are converted from analogue to digital by a DSP processor. There is no AGC in the analogue processing unit, as all processing, including AGC, is done by DSP.
• High-performance analogue front-end: Analogue signal processing is performed by a computer-simulated, high-performance distribution constant filter.
• DDS local oscillator: Instead of the conventional PLL method, the first local frequency is produced by direct digital synthesis. That method enables high-speed frequency switching.
• IF output: An analog IF of 15MHz (+/-7.5MHz) bandwidth is output.
• Digital I/Q output: A digital I/Q signal of 0.9MHz is output via a USB 2.0 interface.
High-precision frequency reference: 0.01 ppm frequency stability of the 10 MHz internal master oscillator is achieved when using the optional GPS receiver unit.
• FFT analyser: Thanks to the onboard FFT processor, 10MHz wide spectrum data can be output at high speed via serial.
• Multi-mode digital voice demodulation: D-STAR, YAESU, ALINCO, D-CR, NXDN, P25, dPMR, DMR, Mototrbo, TETRA. (Mode-dependent restrictions apply)
• Video demodulation: By connecting an external TV monitor, it is possible to demodulate the signal of FM modulation security cameras and analogue TV broadcasts. When you connect the TV monitor, you can check the demodulated video. Not compatible with digital terrestrial television.
• Simultaneous monitoring: 2-band reception, offset reception, triple reception (restrictions apply).
• SD card slot: You can record the received audio, analog and decoded digital, as well as logs.
• 12kHz analogue I/Q output: Allows DRM broadcasts decoding via a PC and dedicated 3rd party software.
• HF direct sampling: When receiving HF signals, the signals are converted directly to digital without entering the mixer. This allows very good linearity characteristics.
