Sinusoidal
In sinusoidal mode, the output is an amplitude-modulated medium
frequency (4 kHz) with 50 Hz sinusoidal beat frequency. The amplitude is
determined by the output level setting and the surge type and rate. The
maximum output is 140 V or 50 mA peak.
For a sine wave the peak output or amplitude is equal to the rms output
multiplied by √2, or, conversely
rms output = peak output x 0.707
Three standard surge patterns are provided. The rest, rise, hold and fall
times for each pattern as a percentage of the complete surge cycle are
shown below.
