The Facility

What is included in this facility

The Control Room

  • Fully automated control station
  • Offline analysis station
  • Monitor equipment
  • Secure access
  • UPS
  • CCTV

The Spherical Scanner

  • Roll-over-Azimuth Spherical Scanner
  • Rotates the AUT (Antenna-Under-Test) over two axes of rotation
  • Probe transmits from static probe tower
  • Probe can be rotated to measure two orthogonal polarisations
  • Equivalent to move the probe over a spherical surface surrounding the AUT
  • Absolute position feedback from synchros - no stepper motors
  • Probe tower can either stand on a sliding platform in the Near-Field or on a Far-Field platform
  • Aligned to high precision with laser tracker

The RF System

  • Currently operates from 2 to 40 GHz
  • 100 dB dynamic range
  • 10000 complex measurements/sec
  • Fully automated

The Anechoic Chamber

  • Anechoic shielded room, delivered by Global EMC
  • Size:  5.9m x 4.2m x 2.8m
  • Absorbers from  Emerson & Cuming:  datasheet
  • Shielding tested up to 39.5 GHz by EMC Hire according to MIL STD 285 procedures
  • Fibre-optic data links to control room
  • Easy access to mounted antenna via clever pathway layout
  • Connectors for DC power and data available on AUT mounting plate
