Auto Trigger
If the specified trigger conditions are not found, triggers are forced and acquisitions are made so that
signal activity is displayed on the oscilloscope. The Auto trigger mode is appropriate when:
•
Checking DC signals or signals with unknown levels or activity.
•
When trigger conditions occur often enough that forced triggers are unnecessary
Normal Trigger
Triggers and acquisitions only occur when the specified trigger conditions are found. The Normal trigger
mode is appropriate when:
•
You only want to acquire specific events specified by the trigger settings.
•
Triggering on an infrequent signal from a serial bus (for example, I2C, SPI, CAN, LIN, etc.) or another
signal that arrives in bursts. The Normal trigger mode lets you stabilize the display by preventing the
oscilloscope from auto-triggering.
Single
Trigger and acquisition only occurs once when the specified trigger condition is found. Single trigger
mode is appropriate when:
•
You only want to capture a single event or a periodc signal.
•
You only want to capture a burst or other unsual signals.
Force Trigger
In the Force trigger mode, when the trigger condition is not met, it will be force triggered after the frame
is acquired. The trigger status in the upper left corner of the screen will be displayed as FStop.
