The Agilent Keysight 11759C is an RF channel simulator designed for testing digital cellular mobile radios under realistic multipath fading conditions. It supports cellular standards such as GSM, NADC, DCS1800, and PDC by accurately simulating fast and slow fading, time dispersion, and Doppler shifts.
