The RTR50 is a next generation remote mounted tracking receiver, designed specifically to track and measure ‘CW’ beacons from commercial satellites. Primarily an L-Band input receiver, the unit is designed to be used for telemetry and control, typically in earth stations using medium to large antennae. The receiver is designed as a versatile and easy-to-use unit, with the primary user interface being via remote control.

The tracking band center frequency can be set accurately using the 1kHz step size Direct Digital Synthesiser (DDS) system. The unit uses a 2kHz Phase Locked Loop (PLL) system to perform signal acquisition and level measurement through coherent detection. The search facility sweeps the frequency to locate a signal in the acquisition band and if a signal is detected the frequency is locked immediately to this beacon. A secondary search is then initiated to look for a more intense signal within the search band. If one is detected then the locked tracking frequency is modified. The process repeats until the largest signal is found in the search band and the anti side-band device is then disabled.

A log amplifier is used to provide an output voltage representing the input power in logarithmic scale, in effect making the input power to output voltage log-conformal. The sensitivity of the logarithmic output is user selectable.

The unit is designed for fast signal acquisition and locking, achieving lock in typically less than 1 second.
