Complete
Automation for DisplayPort Testing
Tektronix’ DP-AUX DisplayPort
AUX Controller automates DisplayPort Physical Layer Source and Sink
Compliance Testing. DP-AUX eliminates the need for user interaction
during testing and the need to use vendor-specific proprietary software.
Engineers can simply select the desired tests to run and work on other
tasks while the tests are being executed. The DP-AUX Stand-alone GUI
can also be used in validation, debug, and characterization of DisplayPort
Source and Sink devices.
DP-AUX connects using USB to a PC,
Tektronix DSA/DPO 70804 (minimum) Oscilloscope, or AWG7102/AWG7122B
Arbitrary Waveform Generator and connects directly to the DisplayPort
Plug Test Fixture (ET-DP-TPA-S) and the DisplayPort Receptacle Test
Fixture (a fixture in the ET-DP-TPA-STX set). The AUX Channel connects
through SMA connectors on the DP-AUX to the SMA connectors on the
DisplayPort Test Fixture. The Hot Plug Detect line connects from the
four-pin header on the DisplayPort Test Fixture to the DP-AUX Auxiliary
Controller using the included Hot Plug Cable.
Source Test
Automation
Two modes of operation are available. For complete
automation DP-AUX is fully integrated into Tektronix’ Source Test
Software (Option DSPT). However, the DP-AUX also includes a stand-alone
GUI that can be used with or without the DSPT software. The DP-AUX
can also be used to support debug, characterization, and verification
activities that do not require the DSPT software. DP-AUX removes the
requirement that a user manually change the output signal of the device
under test by providing automated control of the data rate, voltage
level, data pattern, pre-emphasis level, and by enabling or disabling
SSC. Additionally, the DSPT Source Automation Software acquires all
required waveforms and then performs analysis for each test without
manual intervention. The device under test can then be used for other
testing purposes as soon as the waveforms have been acquired.
Sink Test Automation
Sink Testing no longer requires the
need for proprietary software to read and write DPCD registers to
validate that link training has been successful and to read the error
count of the sink device. DP-AUX sets the receiver up to receive the
frequency lock and symbol lock patterns to validate that link training
was successful. In addition, DP-AUX is used to check the error counter
during the jitter tolerance test to ensure that the errors counted
do not exceed the limit outlined in the DisplayPort Compliance Test
Specification.
