The Keysight (Agilent HP) 8568B is a high-performance, 100 Hz to 1.5 GHz spectrum analyzer renowned for its exceptional frequency stability, accuracy, and sensitivity. Comprising the 85680B RF section and the 85662A IF/display section, it features a 10 Hz minimum resolution bandwidth that enables measurements of very low-level signals in both benchtop and automated test equipment (ATE) environments. Its robust digital architecture supports customizable downloadable programs (DLPs), non-volatile trace storage, and comprehensive GPIB programmability.
