Trigger Types
The oscilloscope allows you to synchronize the display to the actions of
the circuit under test by defining a trigger condition. You can use any
input channel or the Ext Trigger BNC for the source for most trigger
types.

These trigger types are available and are presented in the following order in this
chapter:

• Edge trigger
• Pulse Width (glitch) trigger
• Pattern trigger
• CAN (Controller Area Network) trigger
• Duration trigger
• I

C (Inter-IC bus) trigger
• Sequence trigger
• SPI (Serial Protocol Interface) trigger
• TV trigger
• USB (Universal Serial Bus) trigger
Changes to the trigger specification are applied when you make them. If the
oscilloscope is stopped when you change a trigger specification, the scope will
use the new specification when you press

MegaZoom Technology Simplifies Triggering
With the built-in MegaZoom technology, you can simply Autoscale the waveforms,
then stop the scope to capture a waveform. You can then pan and zoom through the
data using the Horizontal and Vertical knobs to find a stable trigger point. Autoscale
often produces a triggered display.
