Calibrate
The calibrate menu allows you to null out any skew between probes or cables,
remove the effects of offsets in the internal O/E converter, recalibrate the
responsivity of the O/E converter, and check the present calibration status of
the analyzer.

The Skew function changes the horizontal position of a waveform on the dis-
play. The Skew function has a range of ≈ +100 µs. You can use skew to com-
pensate 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 skew two channels
Turn both channels on and overlay the signals vertically.
Expand the time base so the rising edges are at about a 45 degree angle.
Adjust the skew on one of the channels so that the rising edges overlap at the 50 per-
cent points.
