In setup/hold trigger, you need to set the data signal line and clock signal line. The
setup time starts when the data signal passes the trigger level/threshold level and
ends at the coming of the specified clock edge; the hold time starts at the coming of
the specified clock edge and ends when the data signal passes the trigger
level/threshold level again (as shown in the figure below). During the setup or hold,
the data signal must remain a valid pattern. The oscilloscope triggers when the setup
time or hold time is lower than the preset time.
