Equipped with advanced technology, it provides excellent performance for CATV engineers.
We offer the high-speed spectrum analyzer 'DS2831 Series' that enables ingress detection and troubleshooting with excellent sensitivity at a 0dBuV noise floor (@300KHz RBW). It can detect transient noise hidden under upstream burst communication carriers without interrupting service. Additionally, it can measure MER/BER/constellation of terrestrial digital (ISDB-T) signals and 64/256QAM signals at high speed, within 2 to 4 seconds. 【Features】 ■ Spectrum analyzer performance from 4MHz to 1.22GHz (expandable up to 2.15GHz as an option) ■ Downstream and upstream spectrum analysis covering the DOCSIS 3.1 frequency band ■ Spectrum persistence analysis: Any frequency band with a maximum span of 206MHz ■ Built-in upstream signal generation capability (J.83A/B-FEC), etc. *For more details, please download the PDF or feel free to contact us.
