Whether you’re an installer, a contractor, a service engineer or a headend engineer, the Deviser DS2831-C Digital TV Spectrum Analyzer has a  broad suite of customizable tools makes it the ultimate test instrument for validating OFDM/DOCSIS 3.1 networks. Tie it all together with the Deviser EDGE platform for managing assets, firmware upgrades, channel plans, and measurement results.


Key Benefits:

  • Fast Spectrum Analyzer: detect and troubleshoot ingress with exceptional sensitivity of -60dBmV @ 300KHz RBW.
  • Color-Coded Persistence Test: find transient noise hiding under upstream bursty signaling, without disrupting service
  • 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
