Deskew the oscilloscope
This procedure neutralizes any skew in the oscilloscope’s
waveform display.
1 On the 54845A oscilloscope, change the Horizontal scale
to 200 ps/div. You can do this using the large 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 Select Probes.
5 Click Skew </> to deskew Channel 1 and Channel 2 signals
so that both channels cross the 54845A 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 1 volt because the
vertical offset was set to 1 volt in the oscilloscope setup
described on page 38.
