The RFE license is designed for professionals and enthusiasts working with radiofrequency (RF) systems, offering enhanced functionality for antenna and cable analysis. With this license, users can extend the operational range of their MATCH up to the 500 MHz RF band, making it ideal for a wide array of applications in telecommunications, broadcasting, and electronics diagnostics.   This license is tailored for: RF engineers and technicians diagnosing and maintaining transmission lines. Network professionals optimizing antenna systems. Hobbyists and researchers delving into RF analysis within the licensed frequency range. 

Unlock an important features of the RFE license: TDR Chart Mode – utilize Time Domain Reflectometry (TDR) for fault detection and analysis. This mode allows users to locate faults in transmission lines by: sending a short electrical pulse or a step function along the cable. Observing the reflected pulse to calculate Distance to Fault (DTF) using delay measurements, speed of light, and cable velocity factors. Interpreting the amplitude and shape of reflected signals to assess fault characteristics. User OSL Profiles: Supports up to 10 User Open-Short-Load (OSL) profiles, enabling precise calibration for accurate measurements.
