The calibrate menu allows you to null out any skew between probes or cables
and to check the present calibration status of the instrument.

Skew
The Skew function changes the horizontal position of a waveform on the display.
The Skew function has a range of approximately 100 µs. You can use skew to
compensate for differences in cable or probe lengths. It also allows you to place
the triggered edge at the center of the display when you are using a power
splitter connected between the channel and trigger inputs. Another use for
skew is when you are comparing two waveforms that have a timing difference
between them. If you are more interested in comparing the shapes of two
waveforms rather than the actual timing difference between them, you can use
Skew to overlay one waveform on top of the other waveform.

To adjust the skew on two channels
1. Turn both channels on and overlay the signals vertically.
2. Expand the time base, so the rising edges are about a 45 degree angle.
3. Adjust the skew on one of channels, so that the rising edges overlap at the 50
percent points.
