Note: Here and in the
previous screen example,
the Relative Time Reference
and Difference cursors are
used to measure the period
and frequency of the
oscillations on the square
wave, with the result
displayed beneath the grid.
The Reference cursor has
been moved to the falling
edge of the square wave,
while the Difference cursor
has been placed at the
maximum level. Displayed in
the trace label when “
'LII²
5HI
” is selected is the gain
by division and difference in
amplitude between the two
cursors.
On the next screen the Relative Time cursors have been moved to
illustrate how they work:
7LSV
: To display in the trace label each cursor’s absolute amplitude
relative to ground level: Press the menu button to select “
'LII
5HI
” from the “show” menu.
