D-PHY App Saves You Time

The D-PHY conformance test software saves you time by setting the stage for automatic

execution of required electrical tests. The primary difficulty of performing electrical tests for

D-PHY is connecting the oscilloscope to the target device, correctly configuring the scope’s

measurement system for ultimate accuracy, issuing the proper commands to perform the

tests and then analyzing the measured results by comparing them to limits published in the

specification. The D-PHY conformance test software automates this work to provide rapid,

accurate and repeatable test execution. In addition, if you discover a problem with your

product, debug tools in the scope are available to aid in root-cause analysis.

See Table 1 for a complete list of the measurements you can make with the D-PHY

conformance test software.

Easy Test Definition

The D-PHY conformance test software extends the ease-of-use advantages of Keysight’s

Infiniium oscilloscopes to testing D-PHY designs. The Keysight automated test engine walks

you quickly through the steps required to define and configure the tests, execute the tests, and

view the test results. You can select a category of tests all at once or specify individual tests.

The user interface is oriented to minimize unnecessary reconnections, which saves time and

ensures accuracy and repeatability of tests. You can save tests and configurations as project

files and recall them later for quick re-testing or review of previous test. Straightforward menus

let you perform tests with a minimum of mouse clicks.

Figure 1. You can easily select individual tests or groups of test with a mouse-click and customize your

output report based on the test results you want to see.
