Assessment and Verification System for UHF PD Detectors

Key Features:

•  Comprehensive assessment：Comprehensively assess and verify the functionality and performance of UHF PD detectors, 

including sensitivity, SWR, dynamic range, linearity, stability, sampling,continuity, interference resistance, pulse counting, 

pattern recognition & diagnosis, and more.

•  Picosecond pulse generator：Generates picosecond pulses and simulated UHF PD signals with adjustable amplitude, 

frequency, and interval.

•  Professional GTEM cell：Third-party certified GTEM cell with background noise lower than -75dBμV.

•  Discharge pattern simulation：Simulates typical discharge patterns including tip discharge, particle discharge, floating 

discharge, air-gap discharge, and creeping discharge.

•  Pulse counting verification：Generates pulses with fixed or random intervals to verify the continuity of sampling and the 

accuracy of the pulse count functionality.

•  Automated testing：Highly automated all-in-one software performs all testing items and generates test reports with one click.

•  Data storage：Can store the records of all assessed instruments for diagnosis and analysis.
