Trigger controls
Trigger Menu. When it is pressed once, it displays the Trigger Menu. When it is
kept pressed for more than 1.5 seconds, it will show the trigger view, meaning it
will display the trigger waveform in place of the channel waveform. Use the
trigger view to see how the trigger settings, such as coupling, affect the trigger
signal. Releasing the button will stop the trigger view.
Level. When you use an Edge or Pulse trigger, the Level knob sets the amplitude
level that the signal must cross to acquire a waveform. Push this knob to set the
trigger level to the vertical midpoint between the peaks of the trigger signal (set
to 50%).
Force Trig. Use this to complete the waveform acquisition whether or not the
oscilloscope detects a trigger. This is useful for single sequence acquisitions and
Normal trigger mode. (In Auto trigger mode, the oscilloscope automatically
forces triggers periodically if it does not detect a trigger.)
