The trigger delay is used to specify the time relationship between the trigger and
displayed signal.
•
Positive values delay the measurement trigger by a specific period. The delayed
trigger point is the left edge of the screen.
•
Negative values perform a pre-trigger function, displaying a section of the waveform
before the trigger point. The trigger point is indicated by small pointers that appear at
the top and bottom of the screen.
