Cable Return Test System Based on Burst-Mode Data Capture

Utilizing a PC, a Low-Cost Digital Oscilloscope, and a Counter to Capture and Analyze Return Noise and Traffic.

  • Tests Noise Floor Over Time - to identify a bad node
  • Packet Wattmeter - for measuring the signal levels of modem traffic
  • Reports Spectral Characteristics of Burst Noise - to help identify the nature of interference
  • Optional Counter Shows How Much Interference
  • Oscilloscope Shows Nature of Interference
  • Supports Capturing Traces in a Timed, Triggered, Manual, or Mixed Mode - for attended or unattended testing
