Trigger Setting
To keep the observed signal constant on the display, the trigger source must be selected for that channel.
Otherwise, it will be difficult to observe because the signal will be very moving on the display. To choose
the trigger source, trigger menu should be opened by pressing the button shown as 17 in the Figure 3a.
Then, trigger channel and trigger edge should be selected from the menu seen in the Figure 4.
