Sencore's high-performance SLM1456 Signal Level Analyzer can completely test and troubleshoot digital and analog cable system. Today's cable systems are broadband cable networks featuring HD video programming, high-end audio, high-speed data, and telephony. This new technology requires more sophisticated methods of testing by maintenance and installation techs. The SLM1456 provides complete measurement of both analog and digital signals for all your testing needs.

Analyze off-air 8-VSB, cable QAM and cable modem QPSK digital signals with after demodulator tests to more accurately troubleshoot problems with digital reception

aBER: Bit-error-rate after demodulation accurately predicts receiver decoder errors that cause loss of digital signal reception
MER: Modulation error ratio measures digital signal quality (modulation error power vs. signal power)
Constellation Diagram Analysis: Graphs the amplitude & phase of the demodulated digital symbols providing a visual indicator of noise or interference in the transmit/receive equipment or signal path

Features
Analyzes NTSC TV-RF signals off-air or on cable for level, A/V ratio, C/N ratio, and Hum%
Full featured Spectrum Analyzer from 5-870 MHz inspects for interference carriers, shows digital signal flatness and analyzes reverse cable signals
Tests for signal leakage from TV-RF system to avoid disconnection for CLI compliance
Bar graph display shows signal level of 120 channels simultaneously
Teams with Sencore Noise Generator for frequency response testing of TV-RF devices/systems
Documents RV-RF performance by logging channel measurements and printing results
Less than 3 lbs, over 3 hours of continuous battery operation
