Triggering from the Front Panel
The front panel provides quick access to the most frequently used trigger controls. The trigger
readout shows you the state of the trigger system.
The SLOPE, COUPLING, and SOURCE controls only apply to edge triggering. To access the
advanced trigger controls, open the Trigger Setup control window by pushing the ADVANCED
button (See Advanced Triggering on page 240 for more information).
Use this procedure to set up triggers using the front-panel controls.
Prerequisites
1
Set the acquisition system to RUN (the RUN/STOP control
is lighted), and set the vertical and horizontal controls
appropriately for the signal to be acquired.
Select the trigger type
2
Push the EDGE button to select edge triggering. Pushing
ADVANCED opens the Trigger Setup control window to set
up other trigger types.
Select the trigger slope
3
Push the SLOPE button to toggle between POS and NEG:
• POS triggers on a rising edge (positive-going) signal
• NEG triggers on a falling edge (negative-going) signal
You can also set the slope in the Trigger Setup control window.
Select the trigger level
4
To manually change the trigger level for edge triggers (or
certain threshold levels for logic or pulse triggers), turn the
LEVEL knob. You can also set the level in the Trigger Setup
control window.
Set trigger level to 50%
5
To quickly set the edge trigger level to 50% of the waveform
voltage range, push the LEVEL knob. The instrument sets the
trigger level to the halfway point between the peaks of the
trigger signal. This function has no effect for the other trigger
types.
You can also click Set 50% in the Trigger Setup control window.
Select the trigger source
6
Push the up and down arrow buttons to select a SOURCE:
• CH 1 through CH 4 are the input channels. The channel
that you select as a trigger source will function whether it
is displayed or not.
• EXT is a fifth, nondisplayable auxiliary (external) trigger
source. To use the auxiliary trigger, connect the source to
the front-panel AUX IN connector.
• LINE is the AC line voltage. The oscilloscope is used to
generate the trigger and you do not have to input a signal.
The trigger level is fixed at zero volts.
