Measure pop-up menu
(Timing Measure display)
Press and hold the MEAS button to open the Measure pop-up menu. The pop-up
menu enables you to save a timing setting so that you can measure the timing
between input or to match multiple inputs, and to specify the zero point of the
timing display.
Save offset.
Saves the timing of the current input as an offset to the timing
display. This saved timing becomes the zero point for the saved offset mode of
the timing display. This applies to both the cross-hair target in the middle of the
display and the numeric readouts.
The Save Offset function allows you to measure the timing between inputs or to
match multiple signals. Use the Relative To setting to select the definition for the
zero timing offset.
NOTE.
You cannot save the timing offset if either the input or reference is missing
or unlocked. You also cannot save a reference when in internal mode. Saving an
offset in these conditions would lead to misleading results so it is not allowed by
the instrument. A warning message appears on the screen if you attempt to save
the offset when it is not allowed.

If you select Saved Offset , you can save the timing from one signal, and then display the timing relative to that saved
offset.
