The following procedure can be used to setup a mask template for testing
channel to channel delay.
In the oscilloscope setup, the controls should be selected to display the start
edge (channel 1) as the first edge on the display, and the stop edge
(channel 2) as the last edge on the display. The trigger source should be set
to trigger from channel 1. The mask template can be created by using an
external signal source to generate the signals identical to the ones that are
going to be tested.
1
Connect the desired signals to the oscilloscope.
2
Set the signal source(s) to generate a waveform identical to the ones
that you are going to test.
3
Press ±
on the oscilloscope, then press the Mask Test softkey.
4
Create a mask (at the desired tolerance) using Automask. Press
Previous Menu softkey when finished.
Refer to "Create a Mask Template Using Automask" for more information on

softkey.
6
Toggle the
Edit Line
