Deskew the oscilloscope
This procedure neutralizes any skew in the oscilloscope’s
waveform display.
1 On the oscilloscope, make sure the Horizontal scale is 200
ps/div. You can do this using the knob in the Horizontal
setup section of the front panel.
2 Select Setup from the menu bar at the top of the display.
3 Select Channel 1.
4 Click Skew </> to deskew Channel 1 and Channel 2 signals
so that both channels cross the horizontal center line at
the same time, at both ends of the eye (both crossings of
the horizontal center line). The horizontal center of the
graticule line is at 600 mV because the vertical offset was
set to 600 mV in the oscilloscope setup described on
page 33.
5 Select Close in the Channel Setup window.
