Fundamental Waveform Parameters
DG900 Pro allows you to set the frequency/period, amplitude/high level, offset/low
level, and starting phase for fundamental waveforms. You can refer to
Wave
to set the above parameters. Note that Vrms and dBm are not available for the
unit of the fundamental amplitude.
