QPHY-MOST150o Software Option

INTRODUCTION TO QUALIPHY MOST150 OPHY

QPHY-MOST150o is an automated test package performing all of the normative real time oscilloscope tests for sources in accordance with the MOST150 oPHY Automotive Ph ysical La yer Sub-Specification Rev. 1.1, 05/2010. The software can be run on LeCroy Zi and Xi Series oscillosc o pe with at least 2 GHz bandwidth, a sample rate of at least 10GSa/s and 10Mpt of memory. The oscilloscope must also be equipped with the QPHY-MOST150o, DFP2, and either SDM or SDA2 options.

Required Equipment

• QPHY-MOST150o, DFP2, and either SDM or SDA2 options

• Real time LeCroy Oscilloscope meeting the above requirements (at least 2 GHz bandwidth, a

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

o All LabMaster 9 Zi-A and SDA/DDA/WaveMaster 8 Zi-A oscillosc opes o SDA/DDA/WavePro 725Zi-A and higher bandwidth oscilloscopes o WaveRunner 620 Zi and higher bandwidth oscilloscopes o WaveRunner 204 MXi-A/Xi-A Series

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

required.

• LeCroy OE425 Optical to Electrical Converter or equivalent (for optical measurements)

• LeCroy D420 Differential Probe and WL-PLINK (for electrical measurements)

Note: If non-compliance testing is being performed, a pair of matched SMA cables can be used in place of the differential probe. This may require SMA/BNC connectors on some oscilloscope models.

USING QUALIPHY MOST150 OPHY

QualiPHY MOST150 oPhy guides the user, step-by-step, through each of the tests described in the specification: MOST150 oPHY Automotive Physical Layer Sub-Specification Rev. 1.1, 05/2010. T o do this, the user must set up a test session.

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

• All Tests [demo]

• All Tests [differential and optical probe]

• All Tests [differential probe only]

• All Tests [direct connections]

• All Tests [optical probe only]

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 compliance tests. If this is not what the user wants, the variables can be modified (see the QPHY-MOST150o 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.

QPHY-MOST150o Software Option

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.
