Test automation
The application program interface
used by the W2642A GUI to control
the W2642A is also used in test
automation software provided by
Agilent for source and sink physical
layer testing. For source testing, this
feature is provided in the U7232A
DisplayPort source compliance test
software, and is available on versions
later than version 1.7. The U7232A
software was designed specifically
for test automation and will run
unattended after the device capabilities
are defined and the scope connection
details are entered in the software.
This software can run the full
compliance test conditions as specified
in the DisplayPort Compliance Test
Specification or can run specialized
user defined procedures. See Table
2 for the full equipment set for the
elements of the automated DisplayPort
source solution.

For sink testing, the N5990A factory
automation software used with other
standards such as SATA, PCI Express^®
and HDMI, provides the necessary
control to the Agilent equipment and
the device under test. N5990A Option
155 provides the control to the Device
under test through the W2642A Option
AUX channel controller to set the state
and query the registers, for example
the PRBS counter register must be able
to reset to 0, count a given number of
errors, be queried, reset and then count
errors during the jitter tolerance test
and read again. The software guides
you through the connection process
and controls the stress signal generator
as identified in the compliance test
specification. See Table 1 for full
automation solution requirements.
