(1) One PDM (Power Distribution Module) is required per voltage group.
(2) Hold last value: reset to 0 V on both channels; go to a predefined value (between 0 V and full scale) on each channel.
(3) By default, reset to zero on both channels. Each channel individually adjustable: hold the value, go to a predefined value between 0 and 100% of the output range.
