Skew The Skew function changes the horizontal position of a waveform on the
display . The Skew function has a range of +100 s . Y ou can use skew to
compensate for dierences 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
dierence between them. If you are more interested in comparing the shapes
of two waveforms rather than the actual timing dierence between them, you
can use Skew to overlay one waveform on top of the other waveform.
T o skew two channels
1. T urn both channels on and overla y 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.
