The DLSR3 builds on the DLSR and DLSR2 legacy with an upgraded digitizing architecture enabling continuous frequency coverage from 750 to 2150 MHz, while retaining wideband snapshot, API, and X-Midas option-tree features that have been key elements of the DLSR family for over a decade. The forward-looking DLSR3 design provides new features and capabilities with maximum backwards compatibility.

Using multi-rate signal processing techniques, the DLSR3 digitizes multiple L-band inputs, with up to eight independent digital sub-band tuner outputs per input. Tuner data is provided on multiple 10GbE interfaces for distribution to individual clients or broadcast to multiple recipients. All outputs include high-precision, high-accuracy time tags supporting the most demanding downstream applications.

The DLSR3’s unique wideband snapshot feature provides continuous surveys of the entire digitized input signal (up to 2150 MHz) to support downlink evaluation and signal discovery. Snapshots size (up to 5 GB), output rate, and trigger modes are configurable.
