Prerequisites
Tektronix DPO70804/B, DSA70804/B, DPO71254/B, DSA71254/B,
DPO71604/B, DSA71604/B, DPO72004/B, or DSA72004/B oscilloscope.
A minimum of 20 minutes warm-up time for the oscilloscope.
Run SPC (Signal Path Compensation) to assure accuracy of the acquisition
system. Remove all probes from the oscilloscope before running SPC.
Perform deskew to compensate for skew between measurement channels.
Note that it is critical to select Off for the Display Only control in t he deskew
setup window to include the deskew data with saved waveforms.
Terminate all unused connections on the DisplayPort test fixture with 50 Ω
terminators.
Up-to-date versions of the TekScope and DPOJET applications are required
to ensure best operation of this software. The readme file for DPODSPT has
information on the required versions. Ensure that these versions (or later)
are installed on your oscilloscope; update them from www.tektronix.com

oscilloscope application and DisplayPort application simultaneously on separate
monitors, for ease of use.
Instrument Connection
The DPODSPT software can p erform testing on a DisplayPort source
device-under-test (DUT) or on stored waveforms. Direct connection to the DUT
quires at least one skew-matched pair of SMA cables, two or more TCA-SMA
re
connectors, and the DisplayPort test fixture. The test fixture is available from
Tektronix a s part number ET-DP-TPA-STX.
Differential probes P7380SMA or P7313SMA can also be used, and include their
own phase-matched SMA ca ble sets. If probes are not used, phase-matched SMA
cable sets are available from Tektronix as part number 174-4944-01.
Connect oscilloscope channels CH1 and CH2 to the DisplayPort lane to be tested.
You can optionally connect oscilloscope channels CH3 and CH4 to another
DisplayPort lane for inter-pair lane skew testing. Any unused connections on the
DisplayPort test fixture must be terminated with 50 Ω terminators.
