The Agilent/Keysight 8702A is a lightwave component analyzer for characterizing electro-optical, electrical, and optical components in transmission systems. It uses a swept modulation frequency to modulate an optical carrier at a fixed 1300 nm wavelength, enabling high-bandwidth component testing up to 3 GHz. The instrument provides calibrated S-parameter, frequency response, and time-domain measurements across a broad range of lightwave and electrical components.
