MP1800A, use GRL-PCIE4-RX calibration/receiver test software developed by GRL

Anritsu has released a test solution for high-speed serial bus receivers using its MP1800A series signal analyzer and GRL-PCIE4-RX calibration/receiver test software developed by GRL (Granite River Labs).

Digital communication systems must continuously accelerate to keep pace with the explosive growth of data traffic. Receiver testing of PHY devices enabling high-speed data transmission in PCs (Personal Computers) and servers verifies compatible connections by adding stresses such as channel loss and jitter. As the next-generation PCIe Gen4 standard increases the bit rate per line to 16 Gbit/s, more precise calibration is required.

Calibration of receiver test signals is a complex procedure that requires the control of various parameters, such as the addition of emphasis including SJ, RJ, and SSC, as well as various jitter types, and the addition of normal mode and differential mode noise.

In addition, it is also necessary to verify whether these devices are controlled within standard specifications to ensure high reproducibility. Therefore, receiver test automation software must constitute the core of the measurement system that not only simplifies test signal calibration and meets test specifications, but also ensures result reproduction through excellent performance such as low intrinsic jitter, low noise, and high reception sensitivity of BERT (Bit Error Rate Tester).

Streamline jitter resistance testing

This receiver test solution consists of the MP1800A, a noise signal source, a variable ISI channel, a real-time oscilloscope, and GRL's GRL-PCIE4-RX, which enables the system to automatically calibrate complex test signals and simplify jitter immunity testing.

The MP1800A broadband BERT forms a core part of the measurement system, supporting not only PCIe Gen4 but also the excellent waveforms and high receive sensitivity required to evaluate high-speed serial interfaces such as 100GbE and InfiniBand, helping to improve the reproducibility of receiver testing.

This test solution uses GRL-PCIE4-RX software and the MP1800A to simplify calibration for receiver testing and jitter immunity testing, ensuring high reproducibility of results and high efficiency of the device.
