3 In the Channel Menu, press Probe .
4 In the Channel Probe Menu, press Skew ; then, select the desired skew
value.
Each analog channel can be adjusted ±100 ns in 10 ps increments for a
total of 200 ns difference.
The skew setting is not affected by pressing [Default Setup] or [Auto Scale] .
To calibrate a probe
The Calibrate Probe softkey guides you through the process of calibrating
probes.
For certain active probes, such as InfiniiMax probes, the oscilloscope can
accurately calibrate its analog channels for the probe. When you connect a
probe that can be calibrated, the
Calibrate Probe
softkey in the Channel
Probe Menu becomes active.
To calibrate one of these probes:
1 First, plug your probe into one of the oscilloscope channels.
This could be, for example, an InfiniiMax probe amplifier/probe head
with attenuators attached.
2
Connect the probe to the left side, Demo 2, Probe Comp terminal, and
the probe ground to the ground terminal.
3
Press the Channel on/off key to turn the channel on (if the channel is
off).
4 In the Channel Menu, press the Probe softkey.
5 In the Channel Probe Menu, the second softkey from the left is for
specifying your probe head (and attenuation). Repeatedly press this
softkey until the probe head selection matches the attenuator you are
using.

When calibrating a differential probe, connect the positive lead to the Probe Comp terminal
and the negative lead to the ground terminal. You may need to connect an alligator clip to
the ground lug to allow a differential probe to span between the Probe Comp test point and
ground. A good ground connection ensures the most accurate probe calibration.
