MIPI D-PHY Protocol Test Solutions

N4851A/B and N4861A/B MIPI D-PHY Analysis and Stimulus Test

Combine custom traffic generation and real-time analysis to diagnose and characterize your system faster

MIPI D-PHY is a packet-based interconnect standard defined for use in wireless mobile devices as the communication bus between the main components such as the embedded controller (BB-IC) and cameras and displays. When you adopt the MIPI D-PHY standard in your designs, you will face new test challenges during the debug, integration and system validation phases of the development process. To ensure your design operates according to the MIPI D-PHY link and CSI-2 or DSI protocol specification, you need real-time insight on the DUT’s behavior at various protocol levels, and you need to be able to trigger on protocol-specific patterns or error conditions.

To reproduce system problems or run non-regression tests, you often need to create traffic conditions that may be difficult to reproduce with real devices.

The MIPI D-PHY stimulus solution can accelerate your design/debug/test cycle by reproducing these conditions.

The specific nature and operation modes of the MIPI D-PHY serial interconnect makes it extremely difficult to analyze or to stimulate with general-purpose test instruments.

Now you can get the capabilities you need with the N4851A/B and N4861A/B analysis and stimulus solution. The Keysight Technologies, Inc. N4851A/B acquisition probe and the N4861A/B stimulus probe operate in conjunction with Keysight 16800 and 16900 Series logic analyzers to provide the digital serial stimulus and acquisition capabilities required to independently debug and test a MIPI D-PHY component, or integrate your MIPI D-PHY based mobile designs.

Thanks to the modular and scalable architecture of Keysight 16800 and 16900 logic analyzers, the MIPI D-PHY analysis and stimulus measurements can be time-correlated with other measurements (control logic, other serial buses, memory) on the device under test, helping you perform system-level measurements.

Cross triggering capabilities help you observe the activity on a bus when a specific event happens on another bus, helping you find the root cause of complex system-level problems.

With this versatile architecture, you can use the same platform from the bus design phase to system-level test, so you reduce your expenditure on test equipment.

This common, scalable system for protocol analysis and traffic generation protects your financial investment for years to come.
