ICEy - Interference & Compatibility Evaluation System

ICEy is the most advanced reactive near-field E/H-field scanning system for the analysis of EM interference and compatibility (EMI/EMC) in highly integrated electronics. ICEy is the only system that provides accurate EM measurements traceable to international calibration standards and also allows independent interlaboratory comparability of EMI/EMC measurement results. ICEy is a turnkey test bed that supports all features for precise, user-friendly, efficient, fast, and highly autonomous EMI/EMC near-field analyses, developed in close collaboration with industry for the chipset, EM packaging, mobile communications, and medical markets.

  • Camera and 3D DUT surface reconstruction system
  • High-speed EMI/EMC vector signal analyzer
  • High-perfomance measurement control and post-processing PC
  • System and motion control electronics
  • On-site installation, calibration, and validation by our engineers
  • Measurement-ready after system setup with extensive on-site training by our engineers.

Active Fiber Optic Sensors

With our TDS active fiber-optic sensor technology, we take EMI/EMC near-field probe technology to a new level, introducing the first fully RF-EM transparent EMI/EMC near-field probe technology world-wide:

  • Isolated by fiber-optics, the sensor head is floating and does not perturb the DUT EM field distribution
  • The probes are made from low loss, low dielectric constant material that minimally perturbs the DUT EM field distribution
  • The active sensor design offers unparalleled sensitivity by integrating low noise amplifiers in the probe tip
  • The large RF bandwidth of our TDS systems allows measurements resolved in the time or frequency domains with the same probe that depend only on the measurement receiver settings.
  • With a dynamic range of 130 dB, our TDS system is suitable for the most demanding test applications.
  • The TDS system allows measurment of the EM phasor, i.e., the complex EM vector.
  • The miniaturization of the active optical sensor technology mastered by SPEAG makes our TDS probes superb for high-resolution near-field measurements
Precision ICEy provides μm scan resolutions, fully traceable calibrated equipment, and specified measurement uncertainties for arbitrary sources.
Speed An advanced GUI accelerates measurement and setup by providing efficient guidance for visually planning measurement campaigns based on computer vision support and advanced evaluation libraries. Millions of measurement samples can be acquired within a second. Unparalleled measurement speeds are achieved by integrating the vector signal analyzer directly to the PCI-express bus of the control PC.
Versatility A large scanning volume and a fully screened, anechoic EM environment supports a wide range of near-field scanning applications.


A powerful scripting environment allows the user to control external equipment during the scan and to write custom extensions to the control and postprocessing environment. Hardware components, such as probes, can be customized.

Automation The advanced GUI enables computer-aided measurement setup. Measurements can be planned based on a stereoscopic image of the DUT. High-precision computer vision reconstruction techniques are used to automatically acquire contactless, high-resolution 3D images of the DUT surface structure before the measurement. Fully autonomous actual measurements can be performed with the computer-controlled robotic scanning system.
ICEy integrated TDS probes are calibrated in our ISO17025 certified laboratory. Traceable calibration and known measurement uncertainties are essential for achieving excellent inter-laboratory comparability of EMI/EMC measurement results. Calibrated validation sources are also integrated in ICEy for automatic system verification before a measurement campaign, ensuring the reliability of each measurement. Automatic calibration routines and calibration tools for on-site recalibration by the customer also ensure high mechanical integrity for precise alignment of the computer vision surface reconstruction systems.
