Test P ro ce du re
1 Start the automated testing application as described in “Starting the
DisplayPort Electrical Performance Compliance Test Application" on
page 22.
2 Connect the W2641A test fixture or other appropriate fixture to the
device under test (DUT).
3 If you are using one connection, connect the probe to one channel. If
you are using two connections, connect the two probes to two channels
of the oscilloscope. If you are using four connections, connect the four
probes to four channels of the oscilloscope.
4 Connect the SMA to SMP cable to the SMA probe head of one of the
probes and to the data lane connector on the W2641A fixture that you
want to test.
5 Connect the other SMA to SMP cable to the other SMA probe head and
to the data lane on the W2641A test fixture that you want to test.
6 In the DisplayPort Compliance Test Application, click the Set Up tab.
7 Set the Test Mode, Test Type, DUT Definition Settings, Fixture Type,
Connection Type and Number of Channels according to the type of
testing being done. SSC tests are available in the 2 test modes only-
User Defined Conditions and Targeted Characterization Testing.
8 The Deviation HF Variation test is an Informative test, therefore, the
Hide Informative Tests checkbox must be un- checked for this test.
