Complete BERTScope automation for receiver testing

The BERTScope BSAPCI3 Automated PCIe 3.0 Receiver Solution is designed to streamline the tedious and labor-intensive receiver test workflow. No longer is expert PCIe 3.0 domain knowledge required to configure, calibrate, test, and document the results. Fast and accurate BERT-based testing provides high test throughput, intuitive and fast margin testing, and availability of a wide range of debugging tools when further testing is required. The result is high test productivity from setup through to the documentation of results.

This solution can also be used for the latest, emerging storage interfaces such as next-generation SSD and host controller interfaces that utilize NVMe and SATA Express protocols that reside on top of a PCIe 3.0 physical layer.

Test configuration wizard

The BERTScope BSAPCI3 Test Configuration Wizard provides step-by-step guidance for Receiver Test equipment setup and software setup. Clearly drawn block diagrams, cabling configurations, and descriptions simplify the test configuration setup.

Automated stress calibration

An important step in preparing for receiver testing is the calibration of the stress sources to ensure that the stresss applied at the test fixture to the device under test is truly compliant with the test standard. In the past, these calibrations were often the most tedious and error-prone steps in the receiver test setup process. With the BSAPCI3 Automation Software, the calibration of the stress "recipe" is completely automated, including the calibration data. For test configurations that do not change, this step only needs to be performed once, and the stored calibration data is immediately available to be recalled. Engineers can spend less time calibrating, and more time testing.

Loopback initiation and link training

Before the receiver test can start, the device-under-test (DUT) must be put in the proper test mode, called Loopback, where the device is re-transmitting the exact same data that was received. Entering Loopback mode is challenging because of the variety of loopback negotiation sequences across the range of PCIe 3.0 devices. The BERTScope BSAPCI3 Software provides various technique, including Link Training, to train and optimize the link for receiver testing.

BER map

One of the key challenges setting up the link is tuning or determining the optimal RxEQ settings. The BSAPCI3 BER Map feature provides an automated way to scan the PCIe 3.0 TxEQ coefficient matrix to determine the optimal TxEQ for a receiver's RxEQ settings.

Jitter tolerance testing

Jitter Tolerance testing is a critical part of the PCIe 3.0 receiver test and is a single-click operation with the BSAPCI3 Automation Software. With real-time stress adjustment, quick synchronization, and BER testing ability, the BERTScope provides the ideal platform for fast jitter compliance testing. Test results are stored using the built-in database for later recall and report generation.

Beyond testing compliance, the automation software also provides a single-click solution for finding the ultimate tolerance limits of the device under test, termed “search for margin”.

Remote control protocol

The test software can be operated remotely through ASCII commands sent through TCP/IP, giving engineers further flexibility in designing “beyond compliance” tests.

Debugging tools

When a device fails to meet the test requirements, the operator has the power of the full range of BERTScope debugging tools. From intuitive and fast manual stress adjustment to the exclusive error analysis capability and jitter decomposition, the BERTScope can help identify subtle issues that other instruments might miss.

Test setup connection diagrams

The following diagrams show examples of some test setup connections. Icons/Item numbers in the diagrams refer to items described in the Recommended test fixtures, cables, and tools section towards the end of this datasheet.

CAUTION: When tightening cable connectors, to avoid damaging the connectors or cables, use only the SMA torque wrench (item 18) described in the Recommended test fixtures, cables, and tools section of this datasheet. When disconnecting the SMP cables from the test fixtures, use the SMP cable tool (item 19) described in the Recommended test fixtures, cables, and tools section of this datasheet.

Please refer to the following notes when indicated on the individual diagrams.

  • Note 1: For PCIe Link Rx EQ capability, please connect the DPPLink cable (Tektronix part number, 174-6207-xx provided as a standard accessory to the DPP 125C) between the RS-232 connector on the rear panel of the DPP125C and the BSA-DPPLink connector on the rear of the BSA.
  • Note 2: For system calibration, connect the SI Combiner output to CLB RX and oscilloscope to CBB TX (not shown).
  • Note 3: For the PCIe Rx PLL Add-In-Card configuration, use 50 Ω SMA terminators on the Clock Recovery Module Data Output, standard accessory with the Clock Recovery Unit.
  • Note 4: PCI-SIG recommends connecting a hard drive as a power load to your ATX power supply to ensure proper power delivery to your CBB3/CLB3 test fixtures.
