INTRODUCTION TO QUALIPHY MOST50 EPHY

QPHY-MOST50e is an automated test package performing all of the normative real time oscilloscope tests for sources in accordance with the MOST Electrical Physical Layer Specification Rev. 1.1, 06/2006, Version 1.1-00. The software can be run on any LeCroy Zi and Xi Series oscilloscope with at least 500 MHz bandwidth, a sample rate of at least 5GSa/s, and 10Mpt of memory. The oscilloscope must also be equipped with the QPHY-MOST50e, DFP2, and either SMD or SDA2 options.

Required Equipment

• QPHY-MOST50e, DFP2, and either SDM or SDA2 options

• Real time LeCroy Oscilloscope meeting the above requirements (at least 500 MHz bandwidth,

a sample rate of at least 5GSa/s, and 10Mpt of memory)

o All LabMaster 9 Zi-A and SDA/DDA/WaveMaster 8 Zi-A oscilloscopes o SDA/DDA/WavePro 725Zi-A and higher bandwidth oscilloscopes o WaveRunner 606 Zi and higher bandwidth oscilloscopes o WaveRunner 64 MXi-A /Xi-A Series and higher bandwidth oscilloscopes

Note: If a WaveRunner Xi oscilloscope is being used, the XWEB option is additionally required.

• LeCroy ZD1000 Differential Probe or greater (for electrical measurements)

USING QUALIPHY MOST50 EPHY

QualiPHY MOST50 ePHY guides the user, step-by-step, through each of the tests described in the specification: MOST Electrical Physical Layer Specification Rev. 1.1, 06/2006, Version 1.1-00. To do this, the user must set up a test session.

Users choose the test configuration they wish to run. There are six pre-loaded test configurations. They are:

• All Tests [demo]

• All Tests [timing-master device]

• All Tests [timing-slave device]

• Compliance Tests [demo]

• Compliance Tests [timing-master device]

• Compliance Tests [timing-slave device]

These pre-loaded configurations provide quick and easy ways to begin compliance testing. If the user does not want to run any of these configurations, they can create their own custom configuration (see the following section entitled Customizing QualiPHY for details).

The pre-loaded configurations are set up to run all of the tests or just those required for compliance. If this is not what the user wants, the variables can be modified (see th e QPHY-MOST50e Variables section of this manual).

The variables are pre-loaded with the standard settings for compliance testing; however, the user may choose to create their own configuration with the variables set as desired.

QUALIPHY COMPLIANCE TEST PLATFORM

QualiPHY is LeCroy’s compliance test framework which leads the user through the compliance tests. QualiPHY displays connection diagrams to ensure tests run properly, automates the oscilloscope setup, and generates complete, detailed reports.

The QualiPHY software application automates the test and report generation.
