Welcome

The Tektronix TekExpress D-PHY (Opt. 6-CMDPHY / DPHY12 / DPHY21) offers a complete physical layer test solution for transmitter conformance and characterization as defined in the MIPI D-PHY v1.2 and v2.1 specifications. The T solution, along with a Tektronix 6 Series / 6 Series B MSO oscilloscope, provides an easy way to test, debug and characterize the electrical and timing measurements of D-PHY data links.

ekExpress D-PHY automated test

Key Features

• Test time

• Fully automated solution: Performs D-PHY transmitter test with single-button click across High Speed (HS), Low Power (LP), Low Power-High Speed (LP-HS), and Ultra-Low Power State (ULPS) sequences in the D-PHY signal.

• Lets you select individual tests or groups of tests.

• Eye Diagram Capability: Displays the eye diagram of the High Speed signal with option DJA enabled on the oscilloscope for test

1.5.4, Data to clock skew test and test 1.5.7 Data and Clock Eye Diagram.

• Image Snapshot: Option of including the snapshot of the first reference region of analysis in the captured waveform

• 100% test coverage as per D-PHY v2.1, CTS v1.0

• Performs fully-automated tests including Bus Turn Around (BTA) and Ultra-Low Power State (ULPS) measurements, as per D-PHY specifications up to v2.1.

• Measurement variety

• D-PHYTX runs multiple scenarios like Continuous or Burst mode, Termination variations, and varying idle time.

• Transmitter conformance test and beyond (Debug)

• Easily modify limits of test parameters in TekExpress for debug, margin, and characterization testing

• Performs characterization by running TekExpress application in continuous mode to collect data
