The Agilent/Keysight 8757C is a scalar network analyzer that measures amplitude characteristics across microwave components and systems. It delivers swept power measurements with 76 dB dynamic range and supports frequencies from 10 MHz to 50 GHz in coaxial systems, extending to 110 GHz in waveguide configurations. Three detector inputs are standard; Option 001 adds a fourth input for expanded measurement flexibility.
