The Agilent/Keysight 8553B is an RF section module that functions as the front-end tuner in a modular spectrum analyzer system. It operates from 1 kHz to 110 MHz and connects to an IF section (8552A or 8552B) and display unit (141T) to form a complete measurement platform. The module delivers superheterodyne reception with switchable tuning ranges of 0–11 MHz and 0–110 MHz, supporting both frequency-domain swept analysis and fixed-tuned zero-scan operation.
