ST-8853Q 3GHz Spectrum Analyzer with CATV,DVB-C

8853 Series Spectrum Analyzer is portable analyzer, and can be used anywhere in the cable network for analyzing RF signals with a comprehensive scope of measurements, and also can used in analyzing the systems of mobile communication satellite, intermediate frequency and so on.
 
From analysis of digitally modulated signals to test of distortion and noise parameters in the field, this spectrum analyzer is an industry workhorse. The analyzer is specifically focused on the cable TV industry with application specific test features as well. Cable operators typically use the analyzers in the headend and as a tool for elite (high tier) technicians to use for in-depth testing and troubleshooting. They are also used for FCC proof of performance tests. The 8853 Series meet the precise testing needs of the customer and are the greatest assistant
