 The
AOR SR2200 is a DSP powered VHF/UHF receiver
unit covering from 25 MHz to 3 GHz with triple conversion superheterodyne in AM,
NFM, WFM and SFM modes. Thanks to a well designed RFU, the generated IF signal
of 10.7 MHz is of high linearity. Moreover, the demodulated signal is amplified
to a high-definition audio (AF) signal, which can be output to an external
speaker (not supplied) for superb sound. RS232 port and USB port. It is also
compatible with the AR-ONE control head (optional).
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.
-

powerful spectrum scope.
-
Firmware and control software is being continuously improved and new features
are being introduced. (control software is currently under development).
