Benefits of iDDS

Eliminating Vendor Locking for Flexible Configuration

Unlike proprietary systems, iDDS is engineered to be vendor-neutral and hardware agnostic, making it compatible with a wide range of off-the-shelf products. This shift away from vendor locking empowers users to assemble the best components from various suppliers, fostering innovation, flexibility, and cost savings.

Efficient Simulated Testing Made Possible

Imagine a world where testing doesn't demand extensive fuel, wear and tear, or time-consuming instrument setups. iDDS revolutionizes testing by seamlessly integrating simulated data with our Data Acquisition System (DAS). By employing software-based subsystems and real-time hardware-in-the-loop testing, users can spot issues early, solve them affordably, and even simulate entire tests before using any actual resources.

Scaling with Ease for Your Tailored Needs

Whether you're handling 200 or 2000+ channels, our hardware configurations are designed to match your requirements. Gone are the days of paying exorbitantly for support that doesn't align with your system's scale. Instead, iDDS scales costs based on value, supporting smaller systems with cost-effective yet reliable hardware, and enabling powerful test cell expansion. This versatility extends to visualizations too, where you're free to choose tools that suit your preferences without compromising compatibility.
