' This program uses low-level SCPI commands to configure
' the function gnerator to output an PWM waveform.
' The pulse is set up with a duty cycle of 35% and a depth
' of 15%, and will vary in width from 20% to 50% with the
' modulation. The pulse may also be configured in time
' units (pulse width and deviation) rather than duty cycle
' if preferred.
