Satellite Digital Signal Analyzer

DSA 1481

The DSA 1481 Satellite Signal Analyzer provides a comprehensive, low-cost solution to the needs of installers and technicians in today’s complex satellite communications systems. Capable of testing and analyzing digital satellite transponder signal quality with in-depth analysis including Noise Margin, MER, BER, EVM, constellation, and spectral analysis. A simple pass, margin or fail indication simplifies interpretation. Additionally, the FEC value, encryption type, network/program names, video/audio packet IDs are indicated providing advanced verification and troubleshooting information to resolve the toughest challenges.
The DSA1481 provides innovative satellite dish installation and alignment features to speed dish orientation and improve aiming resulting in a more robust dish fade margin. The “Sat Finder” feature references one to three preselected transponders providing positive satellite identification. Once satellite ID is confirmed, an audible beeper guides you to the best alignment position. The Sat Pointer and Max Hold feature combine for a dynamic visual spectrum analyzer guided precision dish alignment.

Advanced features, such as DiSEqC switch/motor control commands, dual LNB simultaneous monitoring, and SCR (single cable commands) provide further utility in controlling satellite systems for ease in alignment and testing. The DSA1481 provides the durability needed for continuous field use and the bright LCD display provides ease of viewing in any environment.
