S-Parameter Files Path
This variable allows the user to specify the path on the oscilloscope that contains the S-Parameter files used for
emulation and/or de-embedding. The default for this variable is
“D:\Applications\EyeDr\USB3. ”
SSC
This variable allows the user to specify whether or not Spread Spectrum Clocking (SSC) is enabled on the
Product Under Test. The SigTest Average UI test has different limits based on whether or not SSC is enabled. By
setting this variable, the correct limit for this test can be used. Select
“Enabled” if Spread Spectrum Clocking is
enabled, otherwise select “Disabled.” The default is “Enabled” because SSC is required by the USB 3.0
Specification.
Stop On Test to review results
This variable gives the user the option to enable Stop on Test mode. When set to “Yes”, the testing pauses after
each test allowing the us er to review the results. The setup is saved so oscilloscope settings can be modified by
the user. When execution is resumed, the setup is recalled. Note that any new acquisition completed while the
testing is paused may cause the testing to misbehave. The default value for this variable is
“No.”
Test Mode
This variable allows the user to decide whether the tests should be run on newly acquired data or if previously
saved waveforms shoul d be us ed. The choices for this variable are
“Acquire New Data” and “Use Saved Data.” If
“Use Saved Data” is selected, the waveforms are recalled from the location specified in the Saved Waveform
Path variable. The default value for this variable is
“Acquire New Data.”
Use PeRT3
This variable allows the users to select if they would like QualiPHY to automate the PeRT
3
to configure the
Product under test for each test. If this variable is set to “No”, the user must have the ability to stimulate their
Product under test to transmit the required test patterns for transmitter testing. The default setting for this variable
is
“No.”
Use RF Switch
This variable allows the users to specify whether or not they have an RF Switch. If this variable is set to “Yes,” the
oscilloscope communicates with the RF Switch and makes the required connections without any user interaction.
If this variable is set to
“No,” the user must connect their signals when prompted. The default value for this
variable is “No.”
PeRT3 Setup
PeRT3 Hostname or IP Address
This variable allows the user to enter the hostname or IP Address of the PeRT3 Server (the machine that the
PeRT
3
is connected to via USB). If QualiP HY is running from a remot e PC and not from the oscilloscope,
“localhost” refers to the oscilloscope. The default value for this variable is “localhost.”
PeRT3 SSC Enabled
This variable allows the user to enable SSC on the PeRT
3 ’s clock output. This is required for receiver testing. The
default for this variable is “Yes.”
Transmitter Tests
Deskew measure mode
This variable allows the user to select the method for deskewing their cables . The choic es for this variable are
“Wizard Method” and “User Defined.” “Wizard Measured” is used to launch the automated deskew measurement.
“User Defined” is used if the us er would like to set the Deskew value in picoseconds variable when the deskew
value is already known. The default value for this variable is
“Wizard Method.”
