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 Δ 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.
