2. Tap the Other panel.
3. Tap the Multi-Channel button.
Use the controls in the Deskew menu to set the deskew parameters to recommended values, based on the nominal propagation delay of
supported probes. The oscilloscope automatically loads the nominal propagation delay values of TPP probes (TekProbe II probes require
use of a TPA-BNC adaptor).
Note: This deskew menu does not actively test and adjust the probe delay between channels; it uses the delay values stored in
supported probes, or a custom propagation delay value that you enter, to set the propagation delay to zero between the reference
channel probe and one or more other probes.
To actively adjust probe delay using a signal, see
Deskew analog input channels - quick visual method
analog input channels - measurement method
on page 64.
Deskew menu fields and controls
Available fields and controls vary with the type of probe that is attached. For more information, consult the probe documentation.
Field or control
Description
From Source
Select from the drop-down list the channel to deskew from (your reference channel for deskewing).
To Source
Select from the drop-down list the channel to deskew to (the channel that you want to match the From
Source reference channel).
Probe
If the oscilloscope recognizes the probe attached to the channel, the Probe field shows the
nomenclature of the attached probe.
If the oscilloscope does not recognize the probe attached to the channel, the Probe field shows a
drop-down list from which you can select the probe that is attached to the selected channel.
If the attached probe is not in the list, select Custom (at the bottom of the list) and enter the probe
propagation delay in the Propagation Delay field.
Propagation Delay
This field lists the default propagation delay of the attached probe. A positive value shifts a channel to
the left.
OK, deskew
Sets the oscilloscope to add or subtract the delay values of the T
o Source channel such that the delay
between the two channels is as close to 0 as possible.

AFG configuration menu
Use the AFG configuration menu to set the output signal parameters for the optional arbitrary/function generator. Use the AFG to simulate
signals within a design or add noise to signals to perform margin testing.
