Agilent Technologies (www.agilent.com) has unveiled a new software for its Infiniium oscilloscopes, the DisplayPort 1.2 source compliance and validation software. A first in the industry, the software delivers a complete compliance test suite for physical layer tests needed for DisplayPort 1.2 source devices.
Its specification defines a digital video/audio interconnect utilized between a computer and a home theatre system or a computer and its monitor. With DisplayPort 1.2, new measurement patterns and methods are created, while the data rate could be doubled to 5.4 Gbs.
The software also robustly addresses the issues of transmitting data at 5.4 Gbs, as compared to inexpensive media such as flexible or standard pc boards, which demands for a pre-emphasis constructs in the transmitter, and the use of a minimum equalization for the receivers in order that the data may be decoded. The transmitter tests require the use of a mathematical worst case on the source prior to the use of a reference equalizer to make the source eye jitter measurements and diagram.
Agilent said that its new software automatically makes these measurements, which builds on the configurability and usability of previous compliance test software.
“We’ve built broad capabilities into our new DisplayPort source test solution because we have confidence in DisplayPort technology and its expected growth,” remarked Jay Alexander, Vice President and General Manager of Agilent’s Oscilloscopes Business.
“DisplayPort technology demands a flexible, configurable tool that can be employed in a variety of use models – from characterization of transmitter integrated circuits to compliance testing of systems. Our DisplayPort compliance test software gives engineers that flexibility and helps them be productive quickly in their DisplayPort characterization tasks.”
