Basic Configuration

The basic configuration of a ICEy-mmW system is composed of:


ICEy-Base is the basic scanning system to support micrometer-precision near-field scans with any ICEy system consisting of:

  • a four-axis (x,y,z, probe roll) precision Gantry positioning system – with total axis travel of 600 × 500 × 120 mm3, 360° (scanning volume of 450 × 450 × 115 mm3 absolute probe positioning accuracy of <±10 μm.)
  • a fully shielded and absorber-backed test chamber
  • a computer vision system for surface reconstruction of the devices under test (detection limit < ± 20 μm)
  • a high-performance industrial-grade PC for system control and post-processing
  • ICEy interface and motion control electronics
  • 24" LCD, mouse, and keyboard

  • supports sensor model calibration (SMC)
  • ISO 17025 accredited calibration

The ICEy software is optimized for accelerated and automated millimeterwave near-field measurements and offers:

  • a scanning mode that provides strong computer aided measurement planning based on stereoscopic images of the device under test with better than 25µm accuracy
  • fully automated scanning, including automatic probe exchange
  • integrated automatic system validation
  • an advanced post-processor for graphical data visualization, result overlay, filtering and data export
  • tailored mmW scanning and evaluation features
  • compliance testing according to IEC/IEEE 63195 and FCC requirements
API A Python interface allows the user to customize and automate the measurement process with simple or extensive scripts.  In-scan hooks can call Python scripts to synchronize external measurement and test equipment with the ICEy scan progress.
Calibration Calibration is performed in SPEAG's ISO17025-certified calibration laboratory.
