Analyze DOCSIS 3.1 and 4.0 downstream and upstream signals and derive signal quality parameters such as MER, BER, constellations, and IQ error plots.


  • Analyze downstream (DS) and upstream (US) coded signals
  • Support for all FFT lengths and data modulation formats
  • Auto detection, demodulation, and decoding of PLC for DS analysis
  • Auto detection of exclusion band for MER and synchronized ACP with US
  • MER, MER summary in symbol/subcarrier, BER, constellation
