Reference
Refer to the Application Examples chapter for an example of triggering on
aberrant
pulses. (See page 44, Triggering on a SpecificPulseWidth.)
Knobs and Buttons
Level Knob. Use to control the Trigger Level.
Set To 50% Button. Use the Set To 50% button to quickly stabilize a waveform.
The oscilloscope automatically sets the Trigger Level to be about halfway between
the minimum and maximum voltage leve ls. This is useful when you connect a
signal
to the Ext Trig BNC and set the trigger source to Ext, or Ext/5.
Force Trig Button. Use the Force Trig button 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
tri
gger.)
Trig View Button. Use the Trigger View mode to display the conditioned trigger
signal on the oscilloscope. You can use this mode to see the following types of
information:
Effects of the Trigger Coupling option
AC Line trigger source (Edge Trigger only)
Signal connected to the Ext Trig BNC
NOTE. This is the only button that you must hold down to use. When you hold
down the Trig View button, the only other button you can use is the
print
button. The oscilloscope disables all other front-panel buttons. The knobs
continue to be active.
