Item Description

Spectrum Analyzer

Featuring the latest technology, the DS2831 affords outstanding performance to the CATV engineer. Its RF features are based on
a portable and true spectrum analyzer with 80dB+ of dynamic range, detecting impairments before they affects the customer. A host of new applications help HE/HUB and eld engineers perform in-service measurements and locate interference. The in-service upstream persistence mode (any frequency band, max span 206 MHz) reveals interference under bursty signaling.

Key Benefits:

  • Fast Spectrum Analyzer: detect and troubleshoot ingress with exceptional sensitivity of -63.5dBmV @ 300KHz RBW.
  • Non-intrusive color coded spectral density persistence test, showing transient noise hiding under upstream bursty signaling
  • MER Measurement: up to 47 dB MER with 48 hours of statistical recording with 1 second resolution
  • Analog TV and SC-QAM: troubleshoot typical analog interference and distortions as well as SC-QAM performance
  • Time-Domain EVS Measurements: uncover interference from LTE signals under downstream QAM carriers with no service interruptions
  • Characterize OFDM carrier performance and DOCSIS 3.1 cable modem performance
  • 7” Capacitive Touchscreen: with excellent touch response and 7 hours of operating time

Key Features:

  • Real spectrum analyzer performance from 4 MHz – 1.22 GHz (optional extension to 2.15 GHz)
  • –  Downstream & Upstream Spectrum Analysis cover DOCSIS 3.1 frequency bands
  • –  Spectrum Persistence Analysis: any frequency band, max span 206 MHz
  • –  In-service Error Vector Spectrum identi es interference under OFDM and SC-QAM carriers with no interruptions in service
  • –  ITU-T J 83 Annex A/B/C, QAM; auto-detects channel parameters
  • –  Full DOCSIS3.1 capabilities with downstream OFDM and 32x SC-QAM bonded carriers, and upstream OFDM transmit feature with 8x SC-QAM bonded carriers
  • –  Forward/Reverse passive non-intrusive sweep (does not require US sweep receivers for up to 195.2 MHz of high resolution sweep response in the Upstream path)
  • –  Integrated Upstream Signal Generator (J.83A/B-FEC)
  • –  Transport stream analysis with TR 101 290 Monitoring, auto- generated program lists, and program-channel mapping
  • –  Gated Measurements: in-service CCN, CSO, CTB, CLDI, DG/ DP, DOM, ICR tests
