46 Infiniium Z-Series Oscilloscopes User’s Guide
2 Using the Oscilloscope
When Trig’d is selected, the oscilloscope must find the trigger before capturing
and displaying 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.
You can also mouse over the Trigger Level field and use the resulting controls to
set a particular trigger level when the scope is set for edge trigger on a particular
channel. You can also drag the trigger reference indicator at the left side of the
display.
