DS8853 portable Spectrum Analyzer
Summary
DS8853/8831 series is portable spectrum analyzer and it is used to analyze RF signals with a comprehensive scope of measurement in the HFC network. This can also be used in analyzing the system of mobile communication, satellite and so on.
The DS8853/8831 series provides CATV, DVB-C and spectrum analysis as below:
CATV Analysis: Level, HUM, Modulation Depth, C/N, CSO/CTB, Cross-Modulation, In Channel Frequency Response, Differential Phase /Gain, Chrominance to Luminance Delay Inequality, etc.
DVB-C Analysis: Constellation, Power Level, MER, BER, EVM, EVS, MER/BER Statistics, etc.
Spectrum Analysis: Very Fast Sweep Time, Small RBW/VBW, High Accuracy, etc.
