SLM 1456 Signal Level Analyzer
The SLM 1456, a full-featured spectrum analyzer from 5-870 MHz, inspects for interference carriers, shows digital signal flatness and analyzes reverse cable signals.
Overview
The SLM 1456 Portable Signal Analyzer is a digital cable analyzer to completely test and troubleshoot your digital and analog cable system. Today's cable systems have changed dramatically. In fact, they are no longer just cable systems, they are broadband cable networks featuring HD video programming, high-end audio, high-speed data, and telephony. All this new technology requires more sophisticated, more detailed methods of testing by maintenance techs and installation techs. The SLM 1456 answers these needs by providing complete measurement of both analog and digital signals.Features
