Trigger Types - Agilent Technologies 54621A User Manual

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.
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.
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
2
• I C (Inter-IC bus) trigger
• LIN (Local Interconnect Network)
• Sequence trigger
• SPI (Serial Peripheral 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 Run/Stop or Single. If the oscilloscope
is running when you change a triggering specification, it uses the new trigger
definition when it starts the next acquisition. You select the trigger type by
pressing the key associated with the desired trigger type.
