AOR AR2300 Operating Manual page 3

INTRODUCTION
Thank you for purchasing the AR2300.
AR2300 is a high-end black-box type receiver with wide band coverage between 40kHz and 3.15GHz. 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) Optional 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) Optional APCO25 Phase 1 digital voice demodulation
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 on SD, as well as backing up receiver settings and memory data.
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.
14) Control via LAN/Internet with optional ARL2300 Ethernet Controller
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 AR2300 will be your monitoring companion for many years to come.
