GAO Announces New CATV Instrument - QAM Analyzer

Toronto, Canada - GAO Tek Inc. (http://www.GAOTek.com)
recommends its new CATV instrument --- GAO1191 QAM Analyzer for DVB signal analysis. This compact-size and high-performance analyzer is designed for both analog and digital TV signal analysis.
In frequency mode, occasional interference can be detected using the peak holding function. What’s more, this functional analyzer easily measures QAM digital channels, analog channels, and FM channels. A built-in COM port makes for simple data communications and storage. The analyzer also features easy to update software.

GAO1191 QAM Analyzer provides the following features:
Analog channel analysis (LEVEL, TILT, C/N)
Digital channel analysis (Constellation diagram, MER, BER)
Spectrum analysis
Limit test function
Auto test function
Multiple users’ channel plan
Built-in COM port
More than 6 hours battery operating time
Light weight
Large LCD screen
