The Sustain pulse is developed using a similar circuit as the Scan Pulse. A series of
specifically timed pulses are applied to FET drivers creating the distinctive sustain
pulse. The drivers switch the voltages (150V, 155V and 175V) at selected intervals
determined by the D board. The basic waveform remains constant but the exact number
of sustain pulses is determined by the amount of luminance required, see the figure
above.
