Running and stopping the trigger
Background
In the trigger Run mode, the oscilloscope
constantly searches for a trigger condition and
updates the signal into the display when the
condition is met.
In the trigger Stop mode, the oscilloscope stops
triggering and thus the last acquired waveforms
stay in the display. The trigger icon at the top of
the display changes into Stop mode.
Pressing the Trigger Run/Stop key
switches between the Run and Stop
mode.
