5 - 26 FUNCTION REFERENCE
DELAY MEASUREMENT
Description:
In the
digital
mode, the MEASURE menu provides a ‘delay’ measurement. This
is an automatic measurement of the time between two 50% levels ("mesials") of
the first leading or trailing edge of two signals. The menu is reached with the key
sequence ‘MEASURE >> MEAS1(2) >> delay’ The lower part of the menu is then
automatically changed to the delay measurement.
Newly acquired signals or signals stored in memory can be used as sources for
this measurement. The ∆ and TRACK controls are used to select the two sources.
Sources have to be traces in the same register memory to avoid any possible
error of making delay measurements between traces that were not part of the
same acquisition.
For each source there is a softkey to select the slope of the edge (leading edge
or trailing edge).
The delay is displayed in the top left corner of the screen (‘del = ....µs’).
Delay = (leading/trailing edge S1 - leading/trailing edge S2)
where: S1 and S2 are source signals S1 and S2
Refer to section MEASURE MENU for details of signal parameters.
