QPHY-USB3-TX-RX TEST CONFIGURATIONS
Configurations include variable settings and limit sets as well, not just test selections. For more information, refer
to the QPHY-US B3-Tx-Rx Test De scriptions and QP HY-USB3-Tx-Rx Variables sections of this manual.
Empty Template
This configuration is intentionally left blank so it can easily be copied and configured to the user’s custom
configuration. The limit set in use is ComplianceLimits. All of the variables are set to their default settings.
Pre-Test (Scope PeRT3)
This configuration is meant to be run prior to running any other configuration. This configuration runs the
Ping.LFPS Support Test to determine if the Product under test supports the necessary modes to fully automate
the running of the remaining tests. A PeRT
3
is required for this configuration.
Demo of Device Transmitter Tests
This configuration runs all transmitter tests using saved waveforms located on the oscilloscope in the
D:\Waveforms\ USB3\ Demo directory on the oscilloscope. This configuration is meant to easily demonstrate the
QPHY-USB3-Tx -Rx capabilities when live signals cannot be tested.
Device Scope Only (Host TX Tests)
This configuration is meant to run all of the transmitter tests for a user that does not have a PeRT
3
or the RF
Switch. All of the variables are set to default except Product Type is set to “Device” and Channel File is set to
“Host11inWith3mCable.s4p.” The limit set is use is ComplianceLimits. The tests that are run are:

Test 1.1 – Low Frequency Periodic Signaling

Test 1.2 – Spread Spectrum Tests

Test 1.3 – Jitter & Eye Diagram Tests
o Test 1.3.1 – Jitter
o Test 1.3.2 – Phase Jitter Slew Rate
o Test 1.3.3 – SigTest Jitter
o Test 1.3.4 – Eye Diagram
o Test 1.3.5 – SigTest Eye Diagram

Test 1.4 – AC & DC Common Mode Test

Test 1.5 – Differential Voltage & De-emphasis Test
Device Scope PeRT3 (Host RX Tests)
This configuration is meant to run all of the receiver tests for a user that has a PeRT
3
but not the RF Switch. All of
the variables are set to default except Product Type is set to “Device”, Use PeRT3 is set to “Yes” and Channel
File is set to “Host11inWith3mCable.s4p.” The limit set used is ComplianceLimits. The test run are:

Test 2.1. – Jitter Tolerance Test
