Agilent Technologies, Inc. introduces 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 source and cable-end physical-layer tests provided in the original software. The addition of automated measurements for compliance and characterization testing offers an advance in the speed and ease of these tests. The U7232A compliance test software version 1.5 offers strict compliance testing according to the DisplayPort Compliance Test Specification (CTS). This version also adds physical-layer validation for link-layer tests which 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.
