QPHY-SAS2 VARIABLES
Use the Upper (A) or Lower (B) Input
For oscilloscope with 2 inputs per channel (Zi series oscilloscope >= 4 GHz bandwidth), this variable allows the
user to decide whether to use the A or B input to run the selected tests. The default value for this variable is
InputA.
Bitrate for SAS2
This variable allows the user to specify the bitrate that is being used for testing. The default value for this variable
is 6e9.
Demo Mode
This variable allows the user to run the tests in demo mode. When you set this value to “Yes,” you can run the
tests in demonstration mode using saved waveforms. The waveforms must be located in the Saved Waveform
Path. During demo mode, the user is still prompted with connection diagrams based on their other variable
selections. This allows the user to experience running the test as it would be run on live signals. The default value
for this variable is
“No”.
Is device either a Target or Initiator
This variable allows the user to specify if the device being tested is a target or initiator. This is use to generate the
proper connection diagram. The default value for this variable is Target.
Which port (A or B) is being tested
This variable allows the user to specify if the port being tested is the primary or secondary port. This is use to
generate the proper connection diagram. The default value for this variable is Secondary.
Path to saved Waveforms for offline test
This variable allows the user to specify the location of the waveforms to be used when running QPHY-SAS2 in
Use Saved Data mode. The default value for this variable is D:\Waveforms\SAS2\.
Save Individual Runs
When this value is set to "Yes", acquired waveforms will be saved in a separate folder for each time the test is run
for example:
D:\Waveforms\SAS2\[Device Under Test]\Run1
When this value is set to "No" waveforms will be overwritten on every run and saved in:
D:\Waveforms\SAS2\[Device Under Test]
This setting has no effect when testing is on saved waveforms.
The default value for this variable is No.
StopOnTest
When set to Yes, the script stops after each test allowing you to view the results. Any new acquisition done may
cause the script to produce unexpected results. The default value for this variable is No.
Test Mode
This variable allows the user to choose to run QPHY-SAS2 on newly acquired data or on previously saved data.
The default value for this variable is Acquire New Data.
Tx Negative Source
The variable allows the user to select the input source used for Tx negative signal. The default value for this
variable is C3.
