3. Software Installation & Initial Setup

Install the SW in the locations listed below.

There are three files associated with the distribution:

1. SAS12GRxTestApplication00069xxSetup.exe – Version number may vary. Install this on the Oscilloscope Windows OS or external host Windows PC. This application will create ‘C:\GRL\Rx Test Solution\Applications\SASRxTest’ directory hierarchy.

2. SASRxTestScopeSetupFilesInstallation.exe –Install this on the Oscilloscope Windows OS. This will place SAS Setup and SAS Filter folders in the ‘C:\TekApplications\DPOJET’ directory hierarchy.

3. SASPatternFilesInstallation.exe – Install this on the BERTScope Windows OS. This will place SAS Configuration and Pattern Files in the BERTScope in the ‘D:\’ directory hierarchy.

Launch and Setup SW

On the BERTScope:

1. Select View > System > Tools Tab

2. Under Utilities Column, press the Remote button.

3. In Remote Window, Select TCP/IP.

4. Change Terminator to “LF”. Press the Connect Button. The window should look like this:

Note: If you see an error popup when pressing the Connect button. Try a different Port: For example, change Port 23 to 21.


5. Note IP Address and Port # on Remote Client. It will be needed to connect BERTScope to automation software.

6. Minimize, but do not close, the Remote Client Window.

On the PC where GRL Framework is installed:

7. Open the GRL Folder under the Windows Start Menu. Click on GRL Framework within the GRL Folder. The GRL Framework will launch.

8. From Application>Rx Test Application dropdown, select “SAS Rx Test”. If the selection is greyed out, license is expired.

If the following error (below) is observed, this means you are running on a free 10daytrial demo license with limited capabilities.

Follow step 14 to enable license.

9. To enable license, go to License>License Details. The following dialog will pop up.


10. Activate License:

a. If you have an Activation Key, please enter in the box provided and press Activate.

The driver for the ISI Generator is available from the ISI Generator manufacturer. Refer to Appendix of this document for driver installation information for supported ISI generators.


4. Getting Started

Now that the SW is installed and initialized, you can begin calibrating the BERTScope for DP1.2b Sink testing.

Session Info :

The information provided in this tab is included in the report. The DUT Information and Test Info are input by the user. The SW Versions information is populated by itself.


Conditions :

In this section, conditions for Testing and Calibration will need to be set. User selects the conditions for testing and for calibration. When calibrating, the application will calibrate the selected SSC Capabilities and Test SJ frequencies that user chooses. The Reference Presets are only useful for testing. When testing, the application will test the selected Reference Presets, SSC Capabilities and Test SJ frequencies that the user chooses.

Recommended procedure:

Step 1: When calibrating, select all conditions, that may be useful for future testing, for calibration and perform the desired calibration tests.

Step 2: When ready for testing, reselect the desired conditions for testing. For example, it may be only necessary to test one SSC Capability at two frequencies for Reference Preset 1. The user would then select the appropriate conditions for testing.

1. Preset Selections: Select all Presets which are desired for testing. For Calibration, the software develops a calibration curve on a set of predefined Preset values.

2. SSC Selection: Check SSC_ON or SSC_ON for SSC Capabilities selection for calibration or testing. This condition is used to denote the DUT’s SSC capabilities.


3. SJ Frequencies: Select SJ frequencies for testing or calibration. If you want to use additional SJ frequencies not specified by the specification, use Custom_SJ1, 2 or 3. The frequency values will be input in the Setup Configurations page under the Custom SJ Frequencies tab.

Setup Configuration :

The Setup configuration is used to mainly configure the application for testing related settings.

1. ISI Generator: User can select ISI equipment that is being used. Select desired ISI Generator from the dropdown menu. Note: Select “None” if using a fixed ISI Channel. This setting is used for calibration as well as testing.

2. User SJ Frequencies: If any Custom SJ frequencies are selected, the application will

include the Custom SJ frequencies selected in the Conditions tab. This setting is used for SJ calibration as well as testing. The values for


3. Presets: In the Presets tab, you can select the Preset settings. Then Nominal Presets are those defined in the specification. If Nominal Presets is selected, the text fields will be greyed out and display default values. If Custom Presets is selected, the user can input user selected values in the text fields. If Optimized Search is selected, then these values will be ignored and user would need to run additional test RX Link Optimized Preset Search to determine the values.


4. PG Delay: The PG Delay tab is used to select if the user wants to define the PG delay value by enabling Overwrite PG Delay. If unsure about the value of this, uncheck the option and perform the PG Delay calibration.

5. BER Automation: The BER Automation tab is used to select the method of determining the BER. Since the SAS specification doesn’t have any defined loopback patterns, the software relies on other methods to get the DUT into loopback. The various methods to enable BER Automation are explained below the picture:

a. Forced Loopback method can be used when the DUT can be controlled using a proprietary software tool. Here the user has to select an appropriate loopback method in the Loopback tab. The BERT will then set the stress and run BER using it’s built in Error Detector. This method requires very little user input

b. Manual method is useful when the DUT does not support any loopback but has a built in error detector to measure BER. In this mode of BER testing, the application will prompt the user to run BER manually and report the Errors which will then be saved in the results.

c. Local Script method can be used when the DUT can be forced into loopback using and external *.exe that will put the DUT into Loopback mode and perform the BER measurement. The user has to provide the path to the exe which the application will call when it is ready to test the BER loopback.

d. Remote Script method is very similar to the Local Script where in both use a User given *.exe file that controls the DUT Loopback and BER measurement.


Only in Remote Script mode, the script resides on a remote (separate) PC. So for this, we have to give the IP and the port number to help the application call the script.

6. Loopback: The Loopback tab is used to help determine the loopback method that the software will use when Forced Loopback is selected in the BER Automation tab. The various methods to enable loopback are explained below the picture:

a. The 'None' option is used when the DUT is in continuous loopback. Here the application assumes that the DUT is in loopback and continues to test BER without any prompts.

b. The Prompt User option needs a user to manually enable the DUT loopback every single time. This option is useful when any loopback method for the DUT is not known or there is a physical method that cannot be automated.

c. The Local Script option here is very similar to the Local Script option in the BER Automation tab. Only difference is here we call a script to put it in loopback instead to doing BER test.

d. Similar to the Local Script option, the Remote Script option is used to force the DUT into loopback using a script located on a remote terminal.

7. Test Params: The Test Params tab is used to determine the test parameters such as BER and Confidence level. Also the Step Size option is used only in the “Compliance+Margin” and “Margin Search” tests to calculate the next step.


Select Tests :

The Select Tests page is the place where the tests that need to be performed are selected. Initially, when starting for the first time or changing anything in the setup, it is suggested to run Calibration first. If the calibration is not completed, the RX Tests will show an error message.

Calibrations:

1. PG Delay Calibration: The delay between the Clock and Data outputs of the BERTScope Pattern Generator going to the input of the DPP has to be calibrated anytime the cables are changed. If the PD Delay value is know, this can skipped and the value can be input in the Setup Configurations tab, explained above.

2. Launch Amplitude Calibration: It will use the 64ones_64 zeroes pattern to calibrate the Launch Amplitudes. This pattern includes highfrequency components (1010) and low frequency components (11111 or 000) to ascertain if initial signal generated by the DPP has equalized amplitudes for highfrequency and lowfrequency components.

3. DeEmphasis Calibration: The pattern uses 64ones_64zeros_64ones_zeros in order to measures deemphasis as accurately as possible.

4. PreShoot Calibration: Similar to the Deemphasis calibration, PreShoot calibration also uses the same pattern to measure preshoot.

5. RJ Calibration: The 1100 clock pattern is used for RJ calibration

6. SJ Calibration: This is also calibrated using the 1100 pattern

7. Eye Opening: The can be done with any frequency content rich pattern. The pattern used here is PRBS15.


Note that a variable ISI channel can be used to more easily adjust the channel to be within the specification. The SW will support automated control of the Tektronix BSAITS or ARTEK CLE1000A2 variable ISI generator.

8. Crosstalk Calibration: For calibrating crosstalk on this setup, we use an All Zeros pattern to just measure the crosstalk that is being injected.

RX Sensitivity Tests:

9. RX Linked Optimized Preset Search: The test permutates through different preshoot and deemphasis settings within spec tolerance to find the optimized preset setting to be used for RX Compliance and Margin Tests. This test will only be carried out if Preset Mode is set to Optimized Search.

10. RX Compliance Test: The compliance test is a jitter tolerance test that measures jitter response at the calibrated levels mentioned in the specification.

11. RX Compliance + Margin Test: This test is very similar to the RX Compliance Test but it measures the jitter tolerance of the DUT at one step above the calibrated levels mentioned in the specification. The step percentage value is from the step size mentioned in the Setup Configurations tab. The margin is a percentage of the calibrated value.

12. RX Margin Search Test: The RX Margin Test is a jitter search test that measures the maximum SJ value that the DUT will handle at the chosen BER. Here the step size is the percentage value of the current applied SJ.

Calibration :

The Calibration page has the calibration targets for each of the parameters that are calibrated to a target value according to the SAS3 Specification. Initially all the values are set to default. If the user wants to use user defined Target Value and or Min/Max Limits, the Use Default Value should be unchecked. Also at any point in time if the default values are needed, just check the box again and default values will replace all the current values.


A PID control is the weight to calculate the next step if target cannot be met with current step. Reduce PID control for finer next step. Increase PID control for bigger next step.

Run Tests :

The Run Tests page has three different options to start the Run. Each option handles the tests selected for the current run differently.

Skip Test if Results Exits. If previous results exists for the test or calibration selected, then the software will skip tests/calibration with existing results.

Replace if Results Exist. If previous test/calibration results exists, then software will replace with new results

(Restart) Delete Existing Results. All previous results will be deleted

Report :

The Report page has all the results from all the test runs displayed. If some of the results are not desired, they can be individually deleted by using the Delete button. Also for a pdf report, click the Generate Report button. To have the calibration data plotted in the report, make sure the Plot Calibration Data box is checked.
