Keysight Technologies Inc. Cable and antenna analyzer
The Keysight N9927AU-305 is an option for the FieldFox handheld analyzers, specifically enabling the Time Domain Reflectometry (TDR) cable measurement capability. This option allows users to analyze cable faults, locate discontinuities, and characterize cable performance in the field. The TDR function provides distance-to-fault measurements and helps in identifying impedance mismatches, making it essential for cable and antenna testing applications. The N9927AU-305 is designed to enhance the diagnostic capabilities of compatible FieldFox analyzers, supporting efficient troubleshooting and maintenance of RF and microwave systems.
