First Complete MIPI M-PHY Test Suite Launched by Agilent Technologies

Recently, Agilent Technologies announced that it had launched a comprehensive MIPI M-PHY test solution for mobile computing customers.

Recently, Agilent Technologies announced that it had launched a comprehensive MIPI M-PHY test solution for mobile computing customers. This test suite can help design engineers turn on, debug and validate all layers, including physical and protocol layers, of their M-PHY devices with its speed 5.8 Gb per second.

MIPI (Mobile Industry Processor Interface) Alliance will settle down the M-PHY specification finally, which could further allow the development of faster, more reliable high-speed interfaces for mobile devices. Meanwhile, M-PHY technology supports a variety of applications, such as, interfaces for monitors, cameras, audio and video devices, memory, power management and communication between baseband and RFIC components.

As for the Agilent solution, it mainly refers to oscilloscopes, protocol analyzers and exercisers as well as bit error-rate testers (BERTs) using custom M-PHY stimulus software. Each device is equipped with custom M-PHY software which can support design teams during the whole process of product design.

Agilent's MIPI program manager, Roland Scherzinger said, “Working closely with customers developing early M-PHY-based silicon allowed us to provide robust M-PHY test solutions even before the final specification became available.” And then, Roland further added, “In addition, we were happy to share our experience in testing high-speed serial technologies in the MIPI workgroups, ensuring robust M-PHY specifications in terms of signal integrity and testability.”

The Infiniium 90000 X series oscilloscope supplies industry-leading, real-time bandwidth up to 32 GHz with the industry’s only 30 GHz probing system. Being the industry’s lowest noise and jitter measurement floor performance, the scope is accurate and ideal choice for Gear 3’s MIPI M-PHY transmitter conformance testing for speeds. By using it, engineers increase their confidence in MIPI M-PHY product performance.

Moreover, MIPI M-PHY receiver testing is supported by Agilent’s high-performance ParBERT 81250A used in multi-lane testing and J-BERT N4903B adopted in single-lane testing. Although MIPI M-PHY receiver test specifications have not yet been settled, engineers are able to use these BERTs for accurate M-PHY receiver tolerance testing, or combine the whole BERT equipment with N5181/2A, E4438C and 81150A signal generators during the using process.

N5990A-165 MIPI M-PHY/ DigRF v4 can save quite an amount of R&D time since it automatically calibrates stress conditions and controls all test electronic component equipment for automated receiver tolerance tests. What’s more, on the basis of MIPI M-PHY, N5343A and N5344A DigRF v4 exercisers and analyzers could offer totally new insights with their range from individual bits to IQ modulated RF signals.
