•
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

Positive Values. For
Time/Div
settings of 50 ms/div and smaller, the
maximum delay is 400 ms.
For
Time/Div
settings of 100 ms/div and larger, the maximum delay is
3200 ms.
Resolution. For delays of 400 ms and less, the resolution is 6.4 ms. For
delays greater than 400 ms, the resolution is 51.2 ms. All entries are
rounded to the nearest multiple of 6.4 ms or 51.2 ms (depending on the
delay value).
