ReleaseNote.TXT for the BERTScope Multi Protocol Receiver Test Automation Software Product: BERTScope Multi Protocol Receiver Testing Version: 1.0.0 Date: Aug 2017 Contents: 1. Introduction 2. Upon First Run 3. Tips 4. Connecting to Oscilloscope 6. Recommendations 7. Known Limitations ================================================================================================================================== 1. Introduction The BERTScope Multi Protocol Receiver Test Automation Software supports TWO protocols: PCIE 3.0 PCIE 4.0 [BETA Version] PCIE 3.0 and 4.0: ------------------ Testing is described in the PCI-SIG PCI Express Architecture PHY Test Specification. It describes both Transmitter and Receiver testing. Transmitter testing is accomplished by connecting the output of the DUT through a PCI-SIG fixture to a real-time oscilloscope and capturing and analyzing waveforms while the DUT is producing a variety of test patterns. Receiver testing is accomplished by connecting the input to the DUT, through a specialized set of fixtures and cables, to the output of a BERT pattern generator that is capable of producing specific PCIe 3.0 test patterns and is capable of adding programmed amounts of random jitter, sinusoidal jitter, differential mode interference, signal amplitude, preshoot, and de-emphasis. The output of the DUT is then sent back to a BERT error detector so that any errors detected can be assumed to come from the forward path (as a result of the DUT experiencing a bad bit-decision). This PCIE 3.0 Test system is for Receiver testing. Tektronix supports transmitter testing using the TEKEXPRESS system. This PCIE 4.0 Test System is for Receiver testing and is a BETA version of it. ================================================================================================================================== 2. Upon First Run Upon the first run of the program, you may want to select a few preferences that are important and that will make future operations more convenient, including the following information: a. Operator - Enter your name b. Database Folder Location - This is the folder where the Microsoft Access 2007 database containing your test results resides. On new installations, the location of this folder defaults to C:\ProgramData\Tektronix\BertScope\RxTest\pcie3.0\Database_Folder\ It can be moved by selecting a new location from the preferences tab. * If you install over the top of an existing v1.1.X installation, the location of the legacy database folder could be in a sub-directory of the target installation folder. In order to recover your existing database to the new location, open the Preferences page and click the Import Legacy DB button. c. TCP/IP Addresses - identify the TCP/IP addresses of your equipment and enter them in the Equipment Preferences. d. Default Calibrations - Each installation, cabling setup, and combination of BERTScope equipment must be calibrated using the calibration wizards. Select saved calibrations as defaults for use on subsequent test runs. The example calibrations should not be used for final testing. ================================================================================================================================== 3. Tips a. The BERTScope TCP/IP Address can be found on the Remote Client after it is initiated and instructed to connect to TCP/IP communications. i. From the BERTScope user interface, select View Button > System. ii. On the Tools tab, press the Remote button. This will launch the Remote Client. iii. After the remote client is running, select TCP/IP communications. The software will automatically connect and display the BERTScope's TCP/IP address. b. The connection between a BERTScope and an associated DPP is critical(BSA Only) and calibration is required. To run an automated calibration, press the Wizard button on the bottom of the DPP view. Pressing the DPP button on the main menu shows a list of available DPP calibrations. c. To start testing, open the Start Connect view and ensure that the TCP/IP addresses of all devices are specified correctly. Press the Connect buttons and view the results. When connected, press the Download button to send the test pattern files for Receiver testing to your BERTScope UserPatterns folder. You must re-download these files whenever they change. d. Before starting the Receiver Test, you must do the following: i. Connect to the BERTScope equipment. ii. Download the test pattern files. iii Select and perform the DPP calibration(BSA only). iv. Select and perform the Amplitude Calibration. v. Select and perform the Stressed EYE Calibration. After verifying the above steps, press the Test Wizard button on the main view to start the Receiver Test. The Wizard will explain how to connect the equipment and the DUT, perform Loopback Training, and then perform BER Testing. The results will be stored in a Microsoft Access database. e. Previously stored Calibration and Test results can be viewed in your browser by pressing the Report button. The results can be saved to a file using the browser's File > Save menu item. ================================================================================================================================== 4. Connecting to the Oscilloscope During Amplitude Calibration and Stressed Eye Calibration, the software connects to a required Tektronix 70000-series real-time oscilloscope to perform calibration measurements. YOU MUST INSTALL the CORRECT VERSIONS of the VISA SOCKET GATEWAY and SIGTEST SERVER to connect to the oscilloscope. These programs have their own installation packages that must be run on the oscilloscope. ================================================================================================================================== 5. Installing the SigTest Application on the Oscilloscope During Stressed Eye Calibration, the software uses the SigTest Application to make calibration measurements. YOU MUST INSTALL the SigTest Application on the oscilloscope to use the SigTest based calibration method. The SigTest Application is available from PCISIG.com for PCIE standard. ================================================================================================================================== 6. Recommendations a) PCIE 3.0 supports SigTestserver version V1.18 and PCIE 4.0 supports SigTestServer Version V1.20 b) Recommended sigetest version for PCIE Gen3 V3.2.0 and for PCIE Gen4 V4.0.30 ================================================================================================================================== 7. Known Limitations a) User needs to have administrative privilege while installing the application b) PCIE 4.0 automated calibration is not supported. c) PCIE 4.0 PRESET and BER Test connection diagrams are not updated. ================================================================================================================================== If you are unable to download or install this software, please contact the Tektronix Technical Support Center: Customers calling within the U.S. call 1-800-833-9200 press 3.
