When the mercury switch (terminals visible at lower right) closes, the capacitors are suddenly connected to the output load of the pulse generator, causing a sharp step in the output voltage. | When the mercury switch (terminals visible at lower right) closes, the capacitors are suddenly connected to the output load of the pulse generator, causing a sharp step in the output voltage. | ||
The starting voltage of the step is typically 0 V. The final voltage is adjustable, both in polarity and magnitude. The range is approximately −10 V to 10 V. | The starting voltage of the step is typically 0 V. The final voltage is adjustable, both in polarity and magnitude.

Early Type 108 units use [[selenium rectifiers]] in the power supply and a [[120-133]] power transformer. | |||
Later Type 108 units use silicon rectifiers in the power supply and a [[120-108]] power transformer. | |||
