01 / OVERVIEW

Making signals programmable

The generator board was designed to produce programmable waveforms with digitally adjustable gain, amplitude and waveform shape. Its architecture combines the waveform-generation circuitry with a complete on-board power supply and STM32-based control.

Key design elements

  • DDS-based programmable waveform generation
  • Digitally adjustable gain, amplitude and output waveform shape
  • Five voltage regulators, including circuitry for four symmetrical supply rails
  • STM32 microcontroller for communication and waveform control
  • Firmware developed for the STM32 control system
