the term "Time Symmetry" means....??


2004-10-28 4:25 am
I'm calibrating an oscillator, and the manual tells me to adjust a pot to correct the "time symmetry" of the square wave, using my scope.

Is this the symmetry of:

...the symmetry (length, size) of the top versus the bottom of square wave ?
(when viewing a single wave) that the flat top is the same length as the flat bottom ?

or am I confused



(p.s. ....I have an analog scope, with cursors.)
