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

•I2C (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 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.
