The SR-4210 provides a complete communications receive system solution by incorporating L or S-Band radio frequency signal reception, phase/frequency/amplitude analog and digital waveform recovery, and optional configurable bit-synchronization and data decoding features. The unique mixture of state-of-the-art RF, analog, and digital circuitry provides an extremely compact package fully supporting low power and high reliability applications.

The receive system provides full remote status and control capabilities via an industry standard RS-232 interface. Simplified local operation is accomplished through menu-driven front panel switches, display and indictors allowing a wide selection of operating formats to meet user requirements.

An industry standard 1U 19 inch rack mountable chassis houses the design, providing the ruggedized structure required for applications ranging from ground stations to mobile transport case environments.

Starting with the downconverter, the design provides high performance signal recovery, supporting a wide dynamic range, narrow to wide signal bandwidths, and near theoretical data/clock recovery even for low Eb/No signals. The soft-radio nature of the implementation allows the design to be tailored to unique end user requirements pertaining to acquisition bandwidth and sensitivity, as well as loop tracking characteristics to account for transmit source platform variations of Doppler, frequency stability, and so forth.
