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

[redrabbit]

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)
....so that the flat top is the same length as the flat bottom ?

or am I confused

??

=RR=

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

If it were an audio product I would say it means only that the marketing department had been reading sci-fi again. Since it is a piece of test equipment it probably means duty cycle- the high time and the low time should be the same length.
