Agilent M8000 allows validation of physical layer designs

Agilent Technologies has launched its M8000 bit error ratio (BER) test solution, which allows developers and system integrators of multi-gigabit network equipment to characterise and validate physical layer designs and to conduct compliance testing in this area. The solution supports various data rates and standards, and helps accelerate insight into the performance margins of high-speed digital devices for computer, consumer, server, mobile computing, and data centre products.

When R&D and validation teams characterise 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 128/130bit and 128/132bit 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-centre 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 characterise 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 characterisation of single- and multi-lane devices operating at data rates up to 16 Gb/s and 32 Gb/s.

The J-BERT M8020A BERT is scalable and expandable to meet future test needs. It supports one to four BERT channels and offers data rates of up to 8.5 Gb/s and 16 Gb/s with an extension to 32 Gb/s. It is based on AXIe, the industry standard for high-performance modular test equipment. The M8020A is controlled from a user interface via USB. All options are upgradeable.
