AOR AR5700D

The highly anticipated AR5700D DIGITAL COMMUNICATIONS RECEIVER is now officially released!

High-end table-top receiver with wide band coverage between 9kHz and 3.7GHz. It supports a variety of digital, as well as analog modes. Some of its outstanding features are:

1)    Digital signal processing:

Input signals after the 45.05MHz IF are converted from analog to digital by a DSP processor. There is no AGC in the analog processing unit, as all processing, including AGC, is done by DSP.

2)    High-performance analog front-end:

Analog signal processing is performed by a computer simulated, high-performance distribution constant filter.

3)    DDS local oscillator:

Instead of the conventional PLL method, the first local frequency is produced by direct digital synthesis. That method allows frequency switching at high speed.

4)    IF output:

An analog IF of 15MHz (+/-7.5MHz) bandwidth is output.

5)    Digital I/Q output:

A digital I/Q signal of 0.9MHz is output via a USB 2.0 interface.

6)    High precision frequency reference:

0.01ppm frequency stability of the 10MHz internal master oscillator is achieved when using the optional GPS receiver unit.

7)    FFT analyzer:

Thanks to the onboard FFT processor, 10MHz wide spectrum data can be output at high speed via serial.

8)    Multi-mode digital voice demodulation:

D-STAR, YAESU, ALINCO, D-CR, NXDN, P25, dPMR, DMR, Mototrbo, TETRA. (Mode dependent restrictions apply)

9)    Video demodulation

By connecting and external TV monitor, it is possible to demodulate the signal of FM modulation security cameras and analog TV broadcasts. When you connect the TV monitor, you can check the demodulated video. Not compatible with digital terrestrial television.

10)    Simultaneous monitoring

2 band reception, offset reception, triple reception (restrictions apply).

11)    SD card slot

You can record the received audio, analog and decoded digital, as well as logs.

12)    12kHz analog I/Q output

Allows DRM broadcasts decoding via a PC and dedicated 3rd party software.

13)    HF direct sampling

When receiving HF signals, the signals are converted directly to digital without entering the mixer. This allows very good linearity characteristics.

Please read this operating manual carefully. This information will allow you to enjoy maximum performance from your receiver. Due to continuous developments of the receiver, firmware and software, we acknowledge that there might be some changes, errors or omissions.

We sincerely hope that the AR5700D will be your monitoring companion for many years to come.
