Coupling:
Select the desired input coupling:
• AC: Only the AC-component of the signal is displayed
• DC: Both the AC and the DC component of the signal is
displayed
Trigger:
Turn on or off the trigger function.
(Note: When AUTO Volt and/or AUTO time is selected, trigger-
ing is also set to AUTO Trg).
• ON: The unit will trigger when the signal reaches the set trigger
level and when the slope corresponds with the selected slope.
• OFF: The unit will not trigger on a specific level. This is also
called 'free running'. The displayed signal will not be stable.
Trg Slope (Trigger Slope):
which the scope will trigger.
• Rising: Trigger when the signal level rises when it reaches the
trigger level.
• Falling: Trigger when the signal level drops when it reaches the
trigger level.
