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.
