RF Scanning Range Alignment

Primary Components

  • Scan Plane
  • Probe
  • Antenna Under Test (AUT)

SA+Tracker replaces traditional range measurement methods

  • Theodolites
  • Mirrors
  • Rotating lasers
  • Depth gages

Scanner Plane Definition

  • Data Acquisition
    • Automated spatial or time-based measurements
    • Reduce time, increase data points with no operator interaction
  • Graphical tolerancing for easy analysis
    • Reference frame defined on best-fit plane

Probe Measurement

  • Measure probe geometry
    • Cylinder
    • End plane
    • Reference points
  • Create probe CL for analysis

Auto adjust with ADM

  • Create Relationship: probe CL to scanner plane
  • SA’s Auto-Measure Mode continually measures ref points to set probe axis square to scanner plane.

AUT Measure and Adjust

  • AUT alignment similar to probe alignment
    • Measure features
    • Create relationships
    • Auto measure ref points to adjust
  • Final alignment: translate probe until CL’s are colinear

Benefits with SA

  • Consolidate manual metrology tools into one automated system
  • Fast, accurate method to measure scanner range components
  • Minimize alignment errors by integrating data capture and analysis into one system.
  • Automated metrology features allow "real-time" range adjustments.
