NVT DAS is designed for high-complexity testing applications requiring:

• High-speed dynamic data acquisition

• Real-time signal processing

• Advanced vibration and thermodynamic analysis

• Centralized management of large channel counts

• Reliable and traceable test data

Its modular structure enables both portable and distributed configurations, making it ideal for field activities as well as advanced test rooms.

Supported Platforms

• NI cDAQ systems

• NI cRIO systems

• NI C-Series modules for real-time acquisition

Supported Signal Types

• Accelerometers

• Displacement transducers

• Eddy current probes

• Key-Phasor sensors

• Thermocouples, Pt100

• Industrial 4–20 mA signals (flow, pressure, power, etc.)

Channel Scalability

• Supports 350+ channels directly through the Real-Time engine

This section merges channel management, instrumentation setup, and industrial connectivity—everything that governs the interaction between NVT DAS and your test environment.

Instrumentation & DUT Configuration

• Full definition of device-under-test parameters

• Advanced configuration of each acquisition channel

• Support for a wide range of measurement sensors

• Automated tracking of calibration certificate expiration, with clear indication of non-compliant transducers

Seamless Integration with Test Room Automation

Native connectivity with PLCs, test bench controllers, and automation systems through standard industrial protocols:
