AOR SR-2200 Professional black box communications receiver
compact high performance black box receiver for professional applications under computer control (USB / RS232) 25MHz - 3 GHz


The SR2200 is a black box wide band receiver intended for commercial / government applications. The frequency range is 25 MHz to 3 GHz. The receiver has no front panel, it is controlled by connection to a computer via an RS232 serial and USB rear panel sockets.
Connectivity.
At the rear of the unit, there is a BNC connector for the antenna, USB and serial control ports, 10.7 MHz I.F. OUT (to connect for example the SDU5600 Spectrum analyzer), external speaker out, phones out, power and a ACC data output interface (discriminator & sound output).

On the front of the unit, there is a connector labelled “Display”. This connector can be used for testing the SR2200 without the need of a PC, and as an extension for future developments.

The SR2200 black box receiver has many advantages over conventional receivers... - Small size and low weight - High sensitivity - High dynamic range.

Availability of additional software functions (control software is currently under development).
The SR2200 (PC) front-panel functions are more flexible and powerful than those of traditional radio. There simply is not enough physical space on a fixed front panel of a traditional receiver for the multitude of settings and options which are available on the SR2200 black box receiver.


Mobile applications: PC-controlled receivers are often used in mobile and portable applications. Connected to a laptop computer, they represent an excellent alternative to conventional spectrum analyzers or other dedicated monitoring equipment.

The processing power of a PC can be used to process received radio signals through third-party software.
