Agilent improves industry's first DisplayPort Source Compliance test software
Dec 07, 2007
Agilent Technologies Inc. has introduced an extension to 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 characterization 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 characterization 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.
