Modular Data Acquisition for Multiphysics Engineering Verification

Engineering organizations face mounting pressure to accelerate validation cycles while managing complex multiphysics requirements across acoustic, structural, and thermal domains. Traditional testing approaches frequently rely on isolated, single-purpose measurement hardware that creates workflow bottlenecks, complicates multi-channel calibration, and restricts collaboration across distributed engineering teams. Addressing these physical verification hurdles requires scalable data acquisition architectures capable of capturing synchronized, high-bandwidth test data that directly correlates with virtual simulations.

 

Modular Architecture for Laboratory and Mobile Testing

Siemens introduced the Simcenter SCADAS ES data acquisition hardware to expand its testing portfolio alongside the Simcenter SCADAS RS rugged field platform. Built on shared modular technology, the hardware accommodates diverse operational configurations across testing laboratories, test benches, and mobile proving grounds.

 

The modular architecture allows engineering teams to scale channel capacity incrementally—from compact channel configurations to high-channel multi-domain setups—without replacing base hardware. The system integrates signal conditioning, power distribution, and communication routing into interchangeable modules, enabling engineers to configure instrumentation around active sensor requirements. Multi-user operating software hosted onboard the hardware operates without external client licenses, allowing distributed teams to configure, monitor, and validate active measurement runs remotely via web-based interfaces.

 

Synchronized Edge Telemetry and Open Ecosystem Integration

Measurement integrity requires continuous data synchronization and full audit traceability across multi-physics sensor suites. Simcenter SCADAS ES delivers synchronized, annotated data packages formatted for rapid integration into artificial intelligence models, digital twin correlations, and finite element simulation routines.

 

To prevent vendor lock-in, Siemens incorporated Test Connect, an open hardware-to-software data exchange interface shared by both SCADAS ES and SCADAS RS platforms. Test Connect allows engineering teams to develop proprietary applications that communicate directly with acquisition nodes, stream live measurement telemetry into external software environments, and interface third-party test instrumentation. For advanced noise, vibration, and harshness (NVH) or structural durability analysis, the hardware links with Simcenter Testlab software to enable edge-to-expert analytical pipelines within the broader Siemens Xcelerator portfolio.

 

According to Bruno Massa, Vice President of Simcenter Testing Solutions at Siemens Digital Industries Software, the platform helps engineering organizations transition away from isolated testing workflows toward a connected, scalable approach that delivers verified, AI-ready data for product verification, digital twin validation, and engineering automation.

 

Additional Context
This section details technical specifications and competitive benchmarking not included in the original product announcement.

 

In dynamic signal acquisition and structural dynamics testing, performance is governed by analog-to-digital converter resolution, phase-matching across distributed channels, and dynamic range. Systems in the Simcenter SCADAS family deploy 24-bit delta-sigma conversion architectures delivering dynamic ranges up to 150 dB and per-channel sampling frequencies up to 204.8 kHz. To preserve phase synchronization across physically separated acquisition frames, the hardware platform utilizes precision time stamping protocols, including IRIG-B and IEEE 1588 Precision Time Protocol, maintaining sub-microsecond time alignment across high-channel strain gauge, accelerometer, and microphone arrays.

 

Within the physical testing and experimental modal analysis sector, Simcenter SCADAS ES benchmarks against modular instrumentation platforms such as HBK QuantumX and LAN-XI systems, Dewesoft SIRIUS modular instrumentation, and National Instruments PXI Express data acquisition chassis. While modular PXI chassis often require specialized chassis controller cards and extensive driver integration, dedicated testing platforms integrate onboard signal conditioning for voltage, IEPE (ICP), charge, bridge, and thermocouple sensors in pre-calibrated modules. Furthermore, providing an open application programming interface via Test Connect establishes a vendor-agnostic streaming pathway that addresses traditional interoperability limits, enabling open data sharing across enterprise product lifecycle management environments.
