Touch the
Vertical
button menu to display the
Vertical Setup
menu control
window.
12.
Touch the Probe
Deskew
button to display the channel-deskew control
window.
13.
Select one of the slower channels.
NOTE
. Do the next step at a signal amplitude within the same attenuator range
(vertical scale) as your planned signal measurements. Any change to the vertical
scale after the deskew is complete can introduce a new attenuation level. A
change in the attenuator setting will give a slightly different signal path. This
different path can cause as high as 200 ps variation in timing accuracy between
channels.
14.
Adjust the deskew time for that channel so that its signal aligns with that of
the reference channel.
15.
Repeat steps 11 and 12 for each additional channel that you want to deskew.
