Anritsu has released a high-speed serial bus receiver test solution using its signal quality analyzer MP1800A series and GRL-PCIE4-BASE-RXA calibration/receiver test software developed by Granite River Labs (GRL). The GRL-PCIE4-BASE-RXA software is sold by GRL from November 30, 2015. [Development background] Digital communication systems must become faster and faster to cope with the explosive growth of data services. The receiver test of the PHY*1 device performs high-speed data transmission in a personal computer (PC) and server to ensure compatible connections when increasing stress, such as channel loss and jitter. The next-generation PCIe Gen4 standard increases the bit rate per channel to 16 Gbit/s, which requires more accurate calibration. Calibration of the receiver test signal is a complex process that requires multi-parameter control, such as adding emphasis and multiple jitter types, including SJ, RJ, SSC*2, etc., and additional common mode and differential mode noise. In addition, equipment must be validated to ensure that these features are controlled within standard specifications to ensure good repeatability. Therefore, the receiver's test automation software not only eliminates the complexity of test signal calibration, but also ensures test specifications, and also relies on the excellent performance of the bit error rate tester (BERT), such as low inherent jitter, low noise and high input. Sensitivity, the bit error rate tester is a key component of the measurement system hardware to ensure repeatability of test results. [Measurement Solution Summary] The receiver test solution consists of the MP1800A, noise source, variable ISI channel*3 and real-time oscilloscope; GRL's GRL-PCIE4-BASE-RXA control system for automatic calibration of complex test signals and simplified jitter tolerance testing. In addition, the MP1800A wideband BERT is a key part of the measurement system. It not only supports PCIe GEN4 but also has excellent waveform quality and high input sensitivity performance for evaluating high-speed serial interfaces such as 100GbE, InfiniBand, etc. Highly repeatable receiver testing is guaranteed. The test solution uses the GRL-PCIE4-BASE-RXA software and the MP1800A to simplify calibration of receiver and jitter tolerance tests while ensuring high repeatability and efficient device testing.

The device converts the logic signal into an actual electrical signal *2 SJ?RJ?SSC The following are abbreviations for each type of jitter, categorized by source and characteristics. SJ: sinusoidal jitter RJ: Random jitter; this unbounded jitter approximates a normal distribution. SSC: Spread spectrum clock. This technique is used to apply jitter on the reference clock signal to reduce EMI. *3 ISI: Intersymbol interference ISI is a kind of distortion that occurs in an electrical signal, and the transmission quality is reduced according to the nonlinear frequency characteristics of the transmission path.
