(see page 3)

The Differential Channel Alignment Application runs on all DSA8300 Digital Serial Analyzer instruments with TekScope software version 6.2 or later, and all TDS/CSA/DSA8000 series instruments running Windows XP and with TekScope software version 5.2 or later.

Go to www.tek.com to download the latest versions of TekScope software.

1. Set the Differential Channel Alignment application preferences (see page 8).

2. Select the module to align (from the list or by selecting the module in the Conﬁguration pane).

3. Select the operation to perform (Align and Save, Align, Load Data, or Load Data and Save).

4. If the Align or Align and Save operation is selected, connect the module (cables, splitters, and adapters) as shown in the Module Conﬁguration pane.

CAUTION. To avoid ESD damage, always wear an ESD wrist strap when connecting cables, splitters, and other signal components to the module or module extender inputs.

5. Click Execute. Follow any on-screen instructions.
