Signal quality analyser earns PCI Express 3.0 test certification

These include PHY layer electrical characteristics and protocol tests, using a high-quality waveform pulse pattern generator (PPG) and high-sensitivity error detector (ED).

The newly certified measurement solution will be on display in the Anritsu booth during DesignCon in Santa Clara (January 31 – February 1, 2018).

The integrated solution addresses the market need to shorten inspection times of high-speed serial bus interfaces during development, which has become increasingly more time-consuming due to the complex measurement methods and need to assure interconnectivity.

The certified test solution integrates the SQA-R MP1900A with the Teledyne LeCroy SDA830Zi-B Serial Data Analyser that has up to 30GHz bandwidth and 80

GS/s sample rate. By offering simple expandability to support future PCI Express 4.0 and 5.0 standards, the solution doesn’t only improve test times but also reduces cost-of-test

Engineers can use the integrated solution to perform calibration for evaluating the PHY layer of PCI Express 3.0 (8 GT/s) add-in cards and system boards, as well as Link EQ tests for verification of the device-under-test (DUT) communications state.

Rx tests to measure the DUT stress tolerance can be performed, as well. Using the SQA-R, which has industry-best performance, and SDA830Zi-B supports high-repeatability testing, as well as troubleshooting analysis.

Inclusion of the Teledyne LeCroy SDA also allows support for transmission-side tests, assuring a comprehensive test solution for PCI Express 3.0 DUT.

The SQA-R MP1900A multichannel bit error rate tester (BERT) has a high-level, high-waveform-quality PPG with 115 fs Intrinsic Jitter, high-accuracy Jitter generation sources (SJ, RJ, SSC, BUJ) and noise source for generating CM-I/DM-I/White Noise. The instrument has a 15mV high-input-sensitivity ED with embedded clock recovery, allowing accurate BER tests to be made even with a very small closed eye.

It also features a Link Training function, as well as a Link Training and Status State Machine (LTSSM) Analysis function not previously available in a BERT.
