Dutycycle; Average Voltage - HP 1652B Getting Started Manual

Duty
CyClC The positive pulse width and the period of the displayed signal are
measured.
duty cycle = ( + pulse width/period) x
100
i3YlS VOltage The rms voltage is computed over one complete period.
Average
voltage The average voltage of the first cycle of the displayed signal is
measured. If a complete cycle is not present, the instrument will
average the data points on screen.
