4 Triggering

Trigger Types
The oscilloscope lets you synchronize the display to the actions of the device under test
by defining a trigger condition. You can use any input channel or the External Trigger
Input BNC as the source for most trigger types.
The following trigger types are presented in this chapter:
• CAN Trigger 97
• Duration Trigger 101
• Edge Trigger 104
• FlexRay Trigger 106
• Glitch or Narrow Pulse Capture 117
• I2C Trigger 120
• I2S Trigger 126
• LIN Trigger 133
• Nth Edge Burst Trigger 136
• Pattern Trigger 138
• Pulse Width Trigger 141
• Sequence Trigger 144
• SPI Trigger 151
• TV Trigger 157
• UART/RS232 Trigger 167
• USB Trigger 171
Changes to the trigger specification are applied when you make them. If the oscilloscope
is stopped when you change a trigger specification, the oscilloscope 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.
MegaZoom Technology Simplifies Triggering
With the built-in MegaZoom technology, you can simply AutoScale the waveforms, then stop the
oscilloscope 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.
