Triggering the Oscilloscope

Trigger modes: Normal and Auto

An introduction to Normal and Auto trigger modes is given on page 80.

1Press the Mode/Coupling key.

2Press the Mode softkey, then select Normal or Auto.

•Normal mode displays a waveform when the trigger conditions are met, otherwise the oscilloscope does not trigger and the display is not updated.

•Auto mode is the same as Normal mode, except it forces the oscilloscope to trigger if the trigger conditions are not met.

Auto mode

Use the auto trigger modes for signals other than low-repetitive-rate signals and for unknown signal levels. To display a DC signal, you must use auto trigger mode since there are no edges on which to trigger.

When you select Run, the oscilloscope operates by first filling the pre-trigger buffer. It starts searching for a trigger after the pre-trigger buffer is filled, and continues to flow data through this buffer while it searches for the trigger. While searching for the trigger, the oscilloscope overflows the pre-trigger buffer; the first data put into the buffer is the first pushed out (FIFO). When a trigger is found, the pre-trigger buffer will contain the events that occurred just before the trigger. If no trigger is found, the oscilloscope generates a trigger and displays the data as though a trigger had occurred. In this case, the background of the Auto indicator at the top of the display will flash, and the Auto indicator will change to Auto? indicating that the oscilloscope is forcing triggers.

When you press the Single key, the oscilloscope will fill pre-trigger buffer memory, and continue flowing data through the pre-trigger buffer until the auto trigger overrides the searching and forces a trigger. At the end of the trace, the oscilloscope will stop and display the results.
