A Mobile Testing Solution Reinvented on Proven Strength

Engineers need tools that work the first time, every time. When data acquisition systems fail or slow testing down, critical road test windows disappear and they can’t be repeated.

Designed for demanding real‑world conditions, HBK’s mobile data acquisition solutions support reliable road load data acquisition with a focus on durability, uptime, simple setup, and dependable system compatibility.

Learn how Fusion RX and supporting software solutions, such as Advantage Connect, are built to support real‑world road load data acquisition challenges.

 

The reality of modern RLDA Testing:

  • Limited test opportunities and high risk of failure: Prototype count is limited. Vehicle time is expensive. Failed tests can’t be repeated.
  • Harsh, real‑world operating condition: Shock, vibration, temperature extremes, and long‑duration driving put continuous stress on systems.
  • Increasing system complexity: More sensors, mixed signal types, higher channel counts, third‑party devices, and distributed teams

OpenDAQ‑based architectures support scalable configurations and integration of mixed sensors and third‑party tools—helping RLDA setups evolve without lock‑in.

What is RLDA?

Road Load Data Acquisition (RLDA) captures real‑world vehicle inputs using an instrumented vehicle equipped with sensors and a data acquisition system. Data is collected while driving on public roads or test‑track surfaces, representing what a vehicle experiences in everyday operation.

Why run an RLDA? To gain clear insight into real‑world durability and performance, validate vehicle components, and support the development of lab‑based testing such as four‑post rigs and full‑vehicle simulators.

RLDA data also plays a critical role in validating virtual models, ensuring simulations reflect real driving conditions.

 

Fusion RX

When the device under test moves, your data acquisition system must move with it. HBK’s Fusion RX is built for the challenges of mobile testing, delivering precise data and reliability wherever your vehicles go.

From rugged roads to extreme environments, it combines outstanding durability with flexibility and versatility —including autonomous logging  and interactive testing.

Because of its modular design and high-performance processing it is ideal for complex automotive and mobile applications, ensuring you capture every essential parameter without compromise.

Don’t just measure—master mobile testing with Fusion RX.
