The S332D cable and antenna analyzer features spectrum analysis capability and optional power meter capability in addition to Return Loss/ SWR (also known as VSWR， for Voltage Standing Wave Ratio) and Cable Loss measurements， as well as Distance to Fault (DTF) analysis using Frequency Domain Reflectometry (FDR). These capabilities give field engineers and technicians the ability to easily identify and solve RF system problems such as coverage， interference， and other path related signal problems. S332D spectrum analysis ranges from 100 kHz to 3 GHz with  smart button measurements - Field Strength， Occupied Bandwidth (OBW)， Channel Power， Adjacent Channel Power Ratio (ACPR)， Interference Analysis and Carrier-to-Interference ratio (C/I).
