DisplayPort v1.1a Measurement Bundle

Revision 1.0, December, 2009
By: ASA
Free

Description

This Measurement Bundle contains a total of 6 Measurement Apps, enabling measurement of all special parameters required by the DisplayPort v1.1a Compliance App. Some of the included Apps are combination Apps which measure multiple statistics directly for the Compliance App. Other included Apps provide Compliance Breakout capability for the combination Apps.
If you are looking for the full DisplayPort Compliance App (which includes this Bundle), ASA recommends that you specifically download that through the Compliance App link below.

Comments

Some of the Measurement Apps included in this bundle combine multiple parameters together, and have separate Apps that measure each of those parameters individually as well. The primary purpose of a combined Measurement App is for use in a Compliance App, where it allows the test to proceed as quickly as possible by minimizing the recalculation that would be required for measuring similar parameters in different Apps. The individual Measurement Apps, on the other hand, are primarily intended for use in a Debug scenario, where having all of the statistics and data for a particular parameter is required.
