Digital The pattern sequencer controls the specified pin(s). If a pattern is currently bursting, the pin immediately switches to bursting the pattern. This option disconnects the PPMU.
Disconnect The I/O switch connecting the instrument channel is open to the I/O connector. If the PPMU is sourcing, it is stopped prior to opening the I/O switch.
Off Puts the digital driver in a non-drive state, disables the active load, disconnects the PPMU, and closes the I/O switch connecting the instrument channel.
Ppmu The PPMU controls the specified pin(s) and connects the PPMU. The pin driver is in a non-drive state, and the active load is disabled. The PPMU does not start sourcing or measuring until DigitalPpmu.Source or DigitalPpmu.Measure is called.
