Keysight P9371A USB Network Analyzer Repair Services
The Keysight P9371A USB is a critical instrument used by RF/microwave engineers, antenna designers, filter manufacturers, PCB signal integrity engineers, and satellite payload teams. When this equipment fails or drifts out of specification, June Company delivers expert repair and NIST-traceable calibration to restore full operational accuracy.
About the Keysight P9371A USB
As a vector network analyzer instrument, the Keysight P9371A USB is designed for demanding applications. Specifically, vector network analyzers measure both magnitude and phase of S-parameters to fully characterize RF/microwave components including impedance, gain, isolation, and group delay. Accurate and reliable performance is essential — measurement drift or component failure can cause costly errors, compliance issues, and project delays.
Common Vector Network Analyzer Issues We Repair
Our repair process addresses the root cause of every issue:
- Receiver calibration drift: addressed with OEM-grade components and verified against traceable standards
- Frequency synthesizer faults: repaired by technicians experienced with Keysight instrumentation
- Mechanical switch degradation: resolved through targeted diagnostics and precision repair techniques
- Test port connector wear and damage: diagnosed through systematic testing and resolved with component-level repair
- Source power leveling errors: identified during our multi-point inspection and corrected to restore specification performance
Calibration and Performance Verification
Every Keysight P9371A USB repair includes NIST-traceable calibration covering key parameters such as S-parameters, Smith chart, and calibration plane. We issue detailed calibration certificates documenting measured performance against manufacturer specifications.
