Protocol Analyzers
Protocol analyzers, or dataloggers, are devices that monitor and record digital and analog signals such as temperature, voltage, current, or digital communications for diagnostics, repair, or optimization of vehicles. They are a common device for all phases of vehicle development, from R&D to production to aftermarket and repair. They support increasing bandwidth across a myriad of protocols and standards and are robust in harsh environments.
Protocol Analyzer Challenges
Modern vehicles, and especially electric vehicles, demand support for faster signaling rates and evolving standards while adhering to small form factors, low power, and high durability to enable active use within the vehicle. These requirements create new challenges for auto tech developers.
- More Sensors, Controls, and Interfaces: Faster signal bandwidths and increased complexity
- In-Situ Operation: Low power, small form factor, and robust operation for use in harsh environments or active drive tests
- Evolving Standards and Requirements: Maintain support for myriad of wired and wireless protocols
- Durability and Versatility: Robust and fault tolerant
Protocol Analyzer Solutions
Protocol analyzers need a variety of interfaces to be supported. ADI’s portfolio includes:
- CAN
- LIN
- SENT
- GMSL
- RS-485/RS-232 or multiprotocol
- USB
- Automotive ethernet
- A2B, C2B, E2B
The common signals monitored by data loggers such as temperature, voltage, or currents are suited to narrow-band oversampling ADCs, with sigma-delta ADCs offering high signal chain integration, and multichannel options are available to monitor many signals at once. ADI offers compact integrated isolated communications, multichannel ADCs, and low power MCU and ADC options for portable applications.
