When R&D and validation teams characterize next-generation designs, they face multiple test challenges. First, the faster data rates of the emerging next-generation digital computer buses, such as PCI Express 4 (with a bit rate of 16 GT/s) and USB 3.1 (with a bit rate of 10 Gb/s), present new signal integrity test challenges. New 128/130-bit and 128/132-bit coding formats complicate error detection and loopback pattern creation.
In addition, widespread adoption of mobile computing devices means more and more R&D and test engineers need to test different implementations of MIPI ports, with new data formats, termination models, multiple lanes and built-in error counting.
Lastly, with the enormous surge in data-center traffic, servers and storage designs must support much higher bandwidths on their backplane and networking ports. Data rates of 25 Gb/s and more on multiple lanes over PC boards, cable or optical interconnects are required by most industry standards, such as 100GbE, CEI and Fibre Channel. Testing such 25-Gb/s receiver ports requires new test capabilities to characterize device tolerance for interference, channel losses and crosstalk. The M8000 Series instruments enables R&D and test engineers to master these challenges, promises Agilent.
The first model in the new M8000 Series is the J-BERT M8020A. It enables fast and accurate receiver characterization of single- and multilane devices operating at data rates up to 16 Gb/s and 32 Gb/s. The M8020A accelerates insight into designs by:
- Streamlining receiver test setup by providing the highest level of integration. It offers built-in jitter injection, 8-tap de-emphasis, interference sources, reference clock multiplication, clock recovery and equalization.
- Ensuring accurate and repeatable measurements by automating in situ calibration of signal conditions.
- Reducing the effort required to bring devices into loopback test mode because the M8020A behaves like a link partner for the device under test and supports interactive link training for PCIe devices.
The J-BERT M8020A BERT is scalable and expandable to meet future test needs. It supports one to
