Your benefits

Time-saving

Reduction of test runs and duration due to the ultra-high bandwidth of PCIe 4.0.

Scalable

Multiple synchronized devices can be used in parallel due to scalable design.

Compatible

Compatibility of the HAD/ADAS measurement software ETAS logging network suite enables seamless integration.

High performance data acquisition with GETK-P4

The infographic visualizes data acquisition with GETK-P4, and data recording and analysis with RALO.

Master the complexity of ADCU data collection and processing

GETK-P4 enables you to collect ADCU-internal data without loss, supporting up to four ARM microprocessors via PCIe 4.0 or lower with a combined data rate of 40 Gbps. GETK-P4 uses a publish-subscribe model for service selection and allows data recording via high-performance logging systems or cost-effective ETAS hard disk solutions.

Applications

Serves as an access device for autonomous driving control units (ADCU), specializing in measuring middleware internal data for advanced driver assistance systems (ADAS) and highly automated driving (HAD), both in the vehicle and in laboratory environments.
Interfaces with ADCU middleware to collect measurement data from adaptive AUTOSAR applications.
Facilitates data collection for analysis, calibration, verification, and certification of HAD functions, making it an integral part of the ADAS measurement solution.

V-GETK: the software-based alternative

The image shows a laptop displaying a semi-transparent, rendering of the V-GETK from ETAS, representing the software-based emulation of the GETK hardware. The V-GETK model appears detailed and technical, emphasizing its virtual nature.

V-GETK is a virtual gigabit probe for software-based emulation of the GETK-P4 hardware. It enables cost-efficient and time-saving measurement data acquisition for ADAS/HAD function development.

Powerful multi-core computers are recommended for the use of the V-GETK, as higher computing power enables more data. Integration takes place as a service on the AUTOSAR adaptive interface ara::com or as a protocol driver in the customized middleware. V-GETK features:

Acquisition and streaming of conventional and complex data
Scalable, modular architecture in combination with ETAS logging network suite
Support for multiple data sources and receivers in many-to-many configuration

V-GETK and GETK-P4 are fully compatible and interchangeable.
