- Anristu’s MP1900A signal quality analyzer was implemented as part of a PCI-Express 6.0 Base Specification test system with the Tektronix DPO70000SX real-time oscilloscope and Synopsys PCI Express 6.0 IP.
- This demonstration was performed during the PCI-SIG Developers Conference at Santa Clara Convention Center, June 21-22, 2022.
PCIe 6.0 utilizes Forward Error Correction (FEC) as a key technology to assure the integrity of 32-Gbaud PAM4 (64 Gbps), low-SNR signals affected by transmission path loss. The result is more complexity associated with evaluating devices under test (DUT). The demonstration implemented a testing solution using automatic Base Specification calibration and signal-quality evaluation by a Tektronix DPO70000SX real-time oscilloscope, combined with Anritsu’s MP1900A supporting error-correction analysis to measure FEC symbol errors in real-time.
In the demonstration, the Anritsu MP1900A generates a stressed compliant signal calibrated by a Tektronix DPO70000SX oscilloscope based on PCI Express 6.0 Base Specification. The signal is transmitted to the Synopsys PCI Express 6.0 IP to measure bit errors using the DUT internal error counter. Additionally, bit errors are measured by the MP1900A PAM4 Error Detector in DUT Loopback mode. Using its FEC function, the MP1900A analyzes and display FEC corrected/uncorrected errors and post FEC error rate, while the Tektronix DPO70000SX real-time oscilloscope analyzes the signal waveforms from the DUT.
In addition to the PCIe 6.0 Base Test, a complete PCIe 5.0 LEQ test was also presented.
The Signal Quality Analyzer-R MP1900A is a BERT for measuring high-speed computer interfaces, such as PCIe 6.0, PCIe 3.0 to 5.0, and USB3.2/4.0, as well as ultra-broadband communications interfaces, including 400 GbE/800 GbE. It is a PCI-SIG-certified instrument for compliance tests up to PCIe 5.0.
