"Edge slope"
Sets the edge direction to be used for delay measurement: positive,
negative, or either edge.
"Level selec-
tion"
Selects the reference level of the measurement source on which the
delay is measured: upper, middle, or lower level.

8.2.5.3 Measuring the delay to trigger
Delay to trigger measures the time between the trigger point and the following slope of
a waveform. If the delay is unknown, it can be measured in two stages - first a coarse
and then a precise measurement.
See also: "Delay to trigger measurement settings" on page 359.
1. Set the horizontal scale and horizontal position so that the trigger point and the
slope both are visible on the screen.
2. Configure the delay to trigger measurement:
a) On the "Overview" tab, select "Delay to trigger" as measurement type.
b) Open the "Setup" tab.
c) Select the source, that is the waveform with the delayed slope.
d) Select the slope, and the reference level.
e) Check the trigger settings.
3. Enable the measurement. Note the result.
4. Turn the horizontal [POSITION / REF POINT] knob and enter the measured delay
as horizontal position.
Thus, the slope is moved to the center of the screen.
5. Adjust the horizontal scale and the horizontal resolution parameters ([RES REC
LEN]) to the required accuracy: "Sample rate", "Resolution", or "Acquisition time".
The trigger is outside the display and is not part of the current acquisition.
6. Repeat the "Delay to trigger" measurement.
Now the delay is measured with high accuracy. You can analyze the variance of
delay values using statistical evaluation and histogram functions.
