The Frequency Agile Signal Simulator (FASS) uses high-speed memory, signal processing, digital-to-analog conversion, and direct digital synthesis for precise signal simulation with unprecedented flexibility. The modulation data source’s digital memory and sequencers store signal characteristics, namely carrier frequency and hop patterns, amplitude, frequency, phase, and pulse modulation data. This data is supplied to the agile carrier synthesizer, where it is processed and converted to an analog signal made up of a carrier and its modulation. Keysight 8791 Model 21 translates baseband signals to between 0.05 and 18 GHz. The smart interface manages data flow and signal generation functions within FASS, as specified by inputs from its menu driven front panel or over GP-IB.
