To compensate for cable delays:
1 Connect the cables you will use in your application to the HP 81200
system's output connectors.
2 Create a scheme of your application in the Connection Editor. Group the
signals to ports and make the connections in the scheme.
3 In the Parameter Editor set the levels for all DUT input and output ports.
4 Open the Deskew Editor (see "How to Start the Deskew Editor" on
page 202).
Per default, generators are selected in the Type field and cable delay
measurement is enabled.
If you have connected the generator outputs in the Connection Editor,
then you can easily mark the outputs for this measurement by clicking
on All connected.
5 Click the Measure button.
The following window pops up.

6 Follow the instructions given in this window.
The measured cable delay value is automatically entered in the table and
the next instruction to connect the next generator output is displayed.
After all marked generators have been adjusted the Automated Deskew
window disappears.
7 Continue with the analyzer cables.
This is essentially the same procedure, except that you don't use the
PROBE connector of the clock module, but one of the generator
channels as a reference. The system proposes the first of the installed
generator channels.
