Source Compliance Testing for DPO/DSA70000B Series Oscilloscopes
DisplayPort is the new digital display interface technology for
computers, monitors, and home-theater systems aimed at lower implementation
costs and improved video performance. DisplayPort 1.1a gives manufacturers
of LCD panels, monitors, graphics cards, PC chipsets, projectors,
peripherals, components, and consumer electronics a next-generation
digital interface that is designed to replace LVDS, DVI, and eventually
VGA. This technology is rapidly moving through early adoption with
chipsets, graphics cards, and first-generation displays now appearing
on the market.
The Tektronix DSA70804 or DPO70804 8 GHz oscilloscopes
are the instruments of choice for testing DisplayPort transmitter
devices, providing the best combination of performance, feature set,
and analysis using the optional DPOJET Jitter and Eye Analysis Tools
software package. The new DPO DSPT software adds an automation layer
that simplifies execution of all the transmitter test measurements
required by the DisplayPort Compliance Test Specification (CTS). DPO
DSPT aids engineers who need to validate their IC, motherboard, and
graphic card designs for compliance with the DisplayPort 1.1a standard.
The software adds predefined test sets that are automatically executed,
reducing test time and minimizing user intervention. A menu-driven
interface allows the user to specify what features their device-under-test
(DUT) supports, and then the software creates a list of the available
tests based on that information. The user can then choose to run the
full suite of tests required for compliance, or to select only certain
tests of interest for debug or troubleshooting. DPO DSPT now supports
compliance testing to both CTS1.0 and CTS1.1, user-selectable from
the menu interface.
The software automatically
recognizes the method of electrical connection (differential probes
or direct-cabled SMA) and configures the oscilloscope input channels.
One lane, two lanes, or all four DisplayPort lanes can be tested simultaneously.
Differential probes are used to connect multiple lanes.
For
each transmitter signal condition (for example, with pre-emphasis
enabled or disabled), DPO DSPT automatically performs all of the selected
tests, properly configuring the oscilloscope settings for each test
and making the required measurements. If the Tektronix DP-AUX DisplayPort
Auxiliary Controller is used in conjunction with the DPO DSPT software,
DPO DSPT can completely automate the process of source device parameter
settings, eliminating user intervention and greatly simplifying the
test process. A report is then generated documenting all measurement
results with the specified limits, pass/fail results, test margins,
and illustrative screenshots where applicable.
