Connection Setup
Test Selection
The connection setup screen lets you enter the details of
connection from the device under test to the oscilloscope. The
connection elements are the test fixture (or test point adapter
(TPA)), the probe heads that connect to the high speed TMDS
lanes, and an optional switch matrix for automated testing.
Lastly, the application allows varied connections such as 2 vs.
4 probes and single-ended vs. differential connections. While
the recommended use model is four probes with single-ended
connection (one data lane), these others are allowed for reduced
capital outlay in test solutions or to facilitate specific testing in
the device characterization stage.
After completing the DUT definition and test connection, you are
ready to make test selections. By clicking on the ‘Select Tests’
tab, you can proceed to select the tests you wish to run.
Figure 8. Test selection in the HDMI compliance software.
In Figure 8, you can see that there are two test suites for
transmitter tests: HDMI 1.4b and HDMI 2.0. For a device that can
perform HDMI 2.0 data rates as well as HDMI 1.4b, the HDMI 2.0
test suite will be shown while the lower data rates (< 3.4 Gbs) only
the HDMI 1.4b tests will be in play. For procedures with multiple
resolutions, the test plan rules of the software will govern the
tests that are run. Test procedures that are performed with only
one resolution or timing will naturally run all tests selected.
