Keysight N9952AU/215 TDR Cable Measurements Option

Overview

The Keysight N9952AU/215 is a TDR Cable Measurements option for FieldFox analyzers that identifies the location and nature of faults along cables using time-domain reflectometry measurements. TDR measurements are based on an inverse Fourier transform of frequency-domain data, enabling engineers and technicians to troubleshoot line faults effectively. Different fault types—resistive, inductive, and capacitive—produce distinct responses, helping pinpoint both location and fault characteristics.

Key Features

• TDR measurements: linear rho, impedance (ohm), and DTF options
• Y-axis display: linear (rho) or impedance (ohm)
• X-axis display: distance in meters or feet
• Identifies both location and nature of cable faults
• Distinguishes between resistive, inductive, and capacitive fault types
