Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

G01R 31/28

Abstract:

Systems, devices and methods for high-speed I/O margin testing can screen high volumes of pre-production and production parts and identify cases where the electrical characteristics have changed enough to impact operation. The margin tester disclosed is lower cost, easier to use and faster than traditional BERT and scopes and can operate on the full multi-lane I/O links in their standard operating states with full loading and cross-talk. The margin tester assesses the electrical receiver margin of an operation multi-lane high speed I/O link with a device under test simultaneously in either or both directions. In a technology-specific form, an embodiment of the margin tester can be implemented as an add-in card margin tester to test motherboard slots of a mother board under test, or as a as a motherboard with slots to test add-in cards.

International Classification:

G06F 11/26
G06F 11/24

Abstract:

A test and measurement system for analyzing a device under test, including a database configured to store test results related to tests performed with one or more prior devices under test, a receiver to receive new test results about a new device under test, a data analyzer configured to analyze the new test results based on the stored test results, and a health score generator configured to generate a health score for the new device under test based on the analysis from the data analyzer.

International Classification:

H04W 24/08
G01R 35/00

Abstract:

Systems and methods for automated recognition of a device under test and retrieving data associated with the device under test based on the recognition. The systems and methods include receiving a recognition key based on an identifying characteristic of the device under test, matching the received recognition key to a stored key in a database, retrieving data related to the stored key when the received recognition key matches the stored key, transmitting instructions to perform an action on a test and measurement device based on the retrieved data, receiving new data related to the device under test, and updating the data in the database related to the stored key with the new data.
