There is a gate on Out 1 for the C05 Immunomudulators - DB preset. This gate is what is responsible for the amplitude on CH1 flashing from 0v to 20v, four times a second.
There is no gate on Out 2, hence why the number is stable on CH2.
This setting is the last set of options in the Signal Settings where you also can specify the Duty Cycle, Amplitude, Offset, and Phase Angle for the program.
