The high-performance receivers are highly tolerant to frequency drift, able to be used in telemetry applications where the transmitter frequency is prone to drifting, for example where the telemetry tramsmitters are operating under severe environmental conditions or are not crystal-controlled. The receiver hunts for the transmitter frequency within user-specified frequency range, at a predefined hunting rate. Using advanced low-noise DDS (Direct Digital Synthesis) facility, the frequency tracking adjustments cause only a minimal disruption to the received signal, not causing more than 0.5% noise (relative to output signal level). If a transmitter is lost, the receiver will automatically commence hunting.

This system is based on a 19” rackmounted industrial computer. The front panel features a high-contrast wide-angle display. There is provision for connection of an external keyboard and mouse.
