The SR-5210 provides a complete communications receive system solution by incorporating 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.
Starting with the down converter, 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 for acquisition bandwidth, sensitivity, and loop tracking characteristics to account for transmit source variations of Doppler, frequency stability, and other operating parameters. Using the latest generation digital signal processing techniques allows upgrades via firmware changes, even for previously fielded systems.
Simplified local operation is accomplished through menu-driven front panel graphical display allowing a wide selection of operating formats to meet user requirements. Key performance values including a Spectrum View and I/Q Plot are available. User selections are accessible locally or remotely via an included RS-232 serial or optional 100baseT Ethernet interface.
Up to 32 Configuration Profiles can be stored with user-defined link names and recalled with a single command, simplifying fast and accurate configuration changes.
For applications requiring diversity combined signals the SR-5210.C is available with an on-board high-performance Pre-Detection diversity combiner. This state-of-the-art combiner can increase link performance in space or range applications supporting dual downlinks.
The SR-5210 is available as a standard 1U 19 inch rack mountable chassis or as PCI cards and API for integration into other systems. The Chassis version is not based on a PC platform, avoiding the requirement for 3rd Party Operating Systems and hard drives and reducing the need for system patches and IT security concerns.
