GAO CATV Instrument: Real-time DVB Spectrum Analyzer series Model A0500025

Leading performance

A0500025 series real time DVB Spectrum analyzer include A0500025A, A0500025B and A0500025Q, which fully utilize DSP(Digital Signal Processing) technologies. They are widely use in telecommunication, broadcasting, CATV and EMC testing field as the most optimized equipment for both indoors and outdoors.

Key features - Real-time DVB Spectrum Analyzer series

• Double scan windows and peak hold function: A0500025 series offers two windows to scan the spectrum and display on the screen at the same time. You won't miss any exceptional signal by 10Hz frequency resolution and you can observe the upstream signal of HFC network.
• TFT LCD: bright display and wide visual angle show you more details during testing and very easy to use.
• Quality and accuracy: all parameters measured are at the same level or better than those of similar models by other competitors.
• Portable design with long operation time: easy to carry and more than 2.5 hours battery operating time.

Introduction - Real-time DVB Spectrum Analyzer

A0500025Q is a newly developed 1GHz portable spectrum Analyzer with TFT LCD, which is specially designed for DVB-C network installation and maintenance. Besides the features inherited from A0500025B, A0500025Q has added professional tools and features which include:

• • CATV analysis: TV channel measurement as well as other key parameters in auto testing, such as CSO/CTB, C/N, MOD, LEVEL, Audio Test, Cross-Modulation, Differential Phase/Gain, Chrominance-to-luminance delay inequality, etc.
• Professional digital signal analysis function: it supports constellation diagram of 16/32/64/128/256QAM/QPSK modulation type and other key parameters in digital signal measurement, for instance, MER, EVM, and Pre/Post BER; it fully complies with ITU-T J.83 Annex A/B/C standard.
• Data storage function: you can perform analysis on selected historical data stored to improve network operation quality.
