2 Using the Oscilloscope
Setting Up Triggers
Use the trigger controls to set the conditions on which the oscilloscope will trigger
and acquire an input signal. You can set up a variety of trigger conditions. Edge
triggers and the parameters for edge triggering can be set up from the front panel.
Trigger configuration settings you make using the user interface are reflected in
the front panel status indicators, and will remain set unless you change them or
press the [Default Setup] key.
Setting the oscilloscope to trigger on an edge
1 Press the [Source] key until the desired source LED is lit.
You can choose any of the channels or the Aux Trig or Line input as the source
for an edge trigger.
2 Press the [Slope] key until the desired slope LED is lit.
You can have an edge trigger on a rising or falling edge, or both.
3 Press the [Sweep] key until the desired LED is lit (Trig’d or Auto).
When Trig’d is selected, the oscilloscope must find the trigger before saving
and displaying captured data.
When Auto is selected, if a trigger does not occur within a certain amount of
time, an acquisition is automatically saved and displayed. In Auto trigger mode,
you are able to see your signals while setting up the desired trigger.
4 Turn the Level knob to adjust the voltage level at which the oscilloscope will
trigger.
Use the Trigger dialog box to select any of the different modes of triggering, the
parameters and conditions for each trigger mode, and advanced configuration
items.
