Based on the industry verified ActiveCore® Platform and AVQ1022 RF Signal Analyzer, AVQ1030 ATSC 3.0 MIMO Receiver and Analyzer provides real-time demodulation, and service data reassembling from two RF signals transmitted over a cross-polarized 2x2 MIMO scheme and modulated per ATSC 3.0 A/322 specification. Beside the MIMO functionality, the receiver offers a comprehensive set of tools for monitoring, analyzing, and troubleshooting the RF signals quality including toughest MIMO reception scenarios of poor antenna ports isolation or cross-polarization discrimination. Detailed analysis of each component of the ATSC 3.0 physical layer framing structure, Avateq’s proprietary in-band interference and link margin estimation, echo profile with monitoring capabilities for SFN applications make the receiver the indispensable tool for RF performance verification in MIMO scheme.

With the ability to provide spectrum sharing and bandwidth usage statistics for each service, the receiver can be used for building metered/managed content delivery networks.
