Agilent / Keysight 86207A RF Bridge, 75 Ohm, 300 kHz to 3 GHz

The Agilent/Keysight 86207A is a 75 Ohm RF bridge for precision reflection measurements spanning 300 kHz to 3 GHz. High directivity across the operating band minimizes coupling between incident and reflected signals, delivering the impedance and reflection coefficient accuracy required for component and system characterization. This instrument integrates with vector network analyzers and RF test equipment to measure return loss and S11 parameters in 75 Ohm environments.

The bridge's impedance matching performance - indicated by its VSWR contribution - supports critical laboratory and field applications where measurement precision is essential.
