DS2831,4~1220MHz Standard Digital TV Spectrum Analyzer high quality
Integrating multiple functions in a very small portable instrument,the DS2808 is a new-generation Digital TV Spectrum Analyzer with a comprehensive measurement suite specifically designed for HFC network testing, troubleshooting, and maintenance.
The DS2808's main functions include Analog TV and Digital TV analysis, DOCSIS 3 0 analysis, Spectrum Analysis, Forward/Return Path Sweep, Upstream Signal Generation, simple Ethernet and Wi-Fi testing, and Auto Test.
With the latest in miniaturized technology, the DS2808 affording outstanding performance to the CATV engineer Its RF features are based on a handheld spectrum analyzer, with 80dB of dynamic range
A host of new applications help HE/HUB and field engineers perform in-service measurements and locate interference Upstream Spectrum Analysis mode offers a persistence mode (any frequency band, max span 206 MHz) that will show interference under bursty signaling.
In the Analog TV mode, when VITS signals are inserted, gated CCN, CSO, CTB, CLDI, DG-DP, DoM, and ICR measurements allow in-service channel testing; the DS2808 can also perform non-intrusive measurements
For DVB-C and CMTS downstream signals, the revolutionary Frequency & Time EVS function enables users to detect coherent distortions hiding under QAM carriers like LTE without interrupting service The DS2808 also supports Transport Stream Analysis, showing reactive bandwidth usage, basic TS structure, TR 101 290, PID view, PCR, PSIP, PAT, and PMT tables.
The DS2808 supports the Toolbox PC software for small- scale applications.The SYNCOR platform manages asset and test data for larger applications. As fiber-optic technology continues to expand into the CATV network space, the DS2808's optical measurement options-including an optical power meter and visual fault location are now standard issue(Fibrescope Optional).
