DisplayPort compliance tests go automatic

The addition of automated measurements for compliance and characterisation testing offers a clear advancement in the speed and ease of these tests.

Agilent Technologies has extended its DisplayPort compliance test software for Infiniium DSO80000 Series oscilloscopes.

Software version 1.5 adds more controlled compliance tests and additional validation tests for link-layer compliance testing to the extensive source and cable-end physical-layer tests provided in the original software.

The addition of automated measurements for compliance and characterisation testing offers a clear advancement in the speed and ease of these tests.

The Agilent U7232A compliance test software version 1.5 offers strict compliance testing according to the DisplayPort Compliance Test Specification (CTS).

The software offers three modes of physical-layer test.

In the first mode, engineers simply select the device capability and the number of tests (one, many or all tests); the tests then run only in the configuration (pre-emphasis, level, bit rate, lane) required by the CTS.

A second mode enables engineers to add or delete configurations.

The third mode allows characterisation testing of any specific configuration and allows for statistical evaluation or repeatability analysis on these results.

Version 1.5 also adds physical-layer validation for link-layer tests.

These tests require that the signal level, pre-emphasis or bit rate of the high-speed link be measured and noted for change in compliance to the link-layer commands.

"This software upgrade adds a significant step in compliance source testing, with expanded test process capability", said Jay Alexander, vice president and general manager of Agilent's oscilloscope business.

"It is an example of our ongoing commitment to the DisplayPort standard".

"Our customers will find the new software simplifies their compliance testing and decreases their overall test time".

The Agilent DisplayPort compliance test solution version 1.5 is available now at a price of US $6000.
