SAT/CATV/TV Signal Analyzer

DSA 1490, DSA 1490-ASI

The DSA 1490 is an all format TV/RF signal analyzer providing today’s engineer a complete portable tool in resolving digital video broadcast, transport, or reception challenges. Capable of testing and analyzing digital satellite signals, digital TV broadcast channels, cable QAM channels, and ASI MPEG streams, it is an all-in-one analyzer. The DSA 1490 features a color touch control screen eliminating multiple menus and pushbuttons achieving a new plateau in user friendliness. Selections are virtually at your finger tip. The large 7 inch screen further provides unprecedented resolution so you won’t miss problems when analyzing critical constellation and spectrum analyzer test screens. An HDMI interface permits test screen viewing on a larger HDMI monitor or for interface to a multi-viewing system.

The DSA 1490 provides powerful digital TV/RF analysis including MER, BER, PER, EVM, noise margin, constellation, and spectral analysis tests. A pass or fail quality indication simplifies interpretation. Additionally, the modulation type, FEC value, encryption type, MPEG services, video/audio program IDs, and MPEG format descriptors are displayed providing advanced RF and MPEG signal analysis.

The DSA 1490 provides a full arsenal of unique special tests and control features to assist technicians in troubleshooting all satellite, cable and TV reception systems. Advanced features include an integrated Spectrum Analyzer, Auto Discovery, SatFinder, DiSEqC commands, Dual LNB monitoring, SCR commands, BarScan, Tilt, Leakage, Ingress, and Logger tests. The DSA 1490 comes equipped with a protective case, DiSEqC switch, AC power adapter, USB cable, connectors, and SMART software.
