  • Waveform Generation Toolbox for Wideband Signal Simulation

    N7509A - Keysight Technologies

    The Waveform Generation Tool provides a simplified interface for baseband modulation of Keysight's wide bandwidth signal simulation solutions, for signals with up to 1 GHz RF bandwidth. Even the most complex signals are defined and implemented easily through the software interface. Signals can be defined through basic parameter entry or from files created in MATLAB or other engineering environments. For each selection in the main menu, a subsequent screen appears, enabling the user to enter the parameters required to define the waveform and invoke the built-in calibration routines. A display on each sub-panel shows the ideal frequency domain waveform calculated from entered parameters. A simulation mode is provided to enable development and operation without connection to the instrument hardware.
