Agilent / Keysight 87511B S-Parameter Test Set, 100 kHz to 500 MHz

The Agilent/Keysight 87511B S-Parameter Test Set is a specialized instrument for RF component characterization across 100 kHz to 500 MHz. This test set measures scattering parameters of one-port and two-port devices—filters, amplifiers, and related RF components—with precision directivity and port match performance. It quantifies signal reflection and transmission coefficients, enabling impedance matching validation and device performance analysis. The 87511B integrates with the Agilent 8751A Network Analyzer in both benchtop and rack-mount configurations.
