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.

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

using automask.

Press the Define Mask Editor softkey.

6 Toggle the Edit Line softkey to select the Min limit line. Use the Mark

and Connect softkeys to edit the minimum line so only the last edge is

present (refer to previous figure).

Refer to "Create or Edit a Mask Using Line Segments" for additional

information.

Toggle the Edit Line softkey to select the Max limit line. Use the Mark

and Connect softkeys to edit the minimum line so only the first edge is

present (refer to previous figure). Press

Previous Menu softkey when

finished.
