Measure Gate
Using Measure Gate, you can narrow the span of the waveform on which to perform parameter
measurements, allowing you to focus on the area of greatest interest. You have the option of
dragging the gate posts horizontally along the waveform, or specifying a position down to
hundredths of a division. The default starting positions of the gate posts are 0 div and 10 div,
which coincide with the left and right ends of the grid. The gate, therefore, initially encloses the
entire waveform.
Note: If you have Grid On Top enabled, you will not see the gate posts in their default position at each end of the grid. But
if you touch either end of the grid, a drag cursor will appear, indicating that you have control of the post and can
now drag it.
