Each RX module has an EEPROM for storing the individual module information such as, TX module
serial number, model name, frequency range, calibration data etc. This is allows user to simply
replace the RX module in the transceiver without redo the alignment and calibration. The data is
transferred between EEPROM and RISC processor via the serial bus.
Field alignments
As the TX and RX module is pre-tuned for the whole operational frequency range and level
adjustment of signal path is done by software (local or remotely), there is no field alignment
required for optimizing the performance.
Specifications
Description
The transceiver is a digitized, software upgradable radio, The exciter and the receiver can be
configured as base station, repeater or the stand-alone unit. The exciter normally has maximum 5
Watt output which is used to drive a high power amplifier. It can also be used alone in lower power
applications. The output power can be preset between 0.3 and 5 watts. All necessary control and
600 ohm line interface circuitry is included.
Channel Capacity
Although most applications are single channel, it can be programmed for up to 256 channels (from
CH0 to CH255). Each channel can have it’s own name, TX/RX frequencies and profiles.
Sub Audio Signaling
Full EIA CTCSS capability as well as nonstandard sub tones are built into the modules. The CTCSS
tone can be programmed for each channel in their profiles. This means each channel can represent
a unique TX/RX and tone frequency combination.
Channel Programming
The channel information is stored in Flash memory and can be programmed via the Ethernet, USB
or RS232 interface using a Host PC and RF Technology’s Service Kit software.
Channel Selection
Channel can be select by Service Kit or front panel buttons (if enabled).
Physical Configuration
The transceiver is designed to fit in a 19-inch rack mounted frame. The installed height is 4 RU
(178 mm) and the depth 350 mm. The transceiver is 63.5 mm. The weight of the transceiver is
approximately 1.6kg
