Signal Transmitter/Receiver

• Anritsu Scorpion Series Vector Network Analyser

Measurement System

• Orbit/FR complete FR959 package including software & hardware.

• Orbit positioner system Operates semi or fully automated for extremely accurate repeatabilty and consistency. Simultaneous 1 to 100 frequencies per test. Multiple elevation cuts or multiple azimuth at almost any increment in degrees for elevation.

Control Room

• Includes Anritsu separate analyser for fast SWR/ Return Loss measurements.

• Dual video camera in-chamber camera displays, materials and tools to permit rapid construction of basic prototypes and structures.

AUT (Antenna Under Test) Facilities, Capabilities, Fixtures Calibration

• Maximum AUT weight using existing fixtures and supports is 20 Lbs. Heavy or heavier antennas can be supported for testing using custom fixtures or adapted fixtures. Maximum antenna size, 36 to 48" depending on type weight distribution.

• Polarization: Vertical or Horizonal, Dual Polarization and Circular Polarization.

• Fixtures include human hand simulator, Ground planes 12", 36", 1 meter with and without 2" or 4" rolled edges to meet certain test standards. Elevation and Azimuth various non metallic supports, holders and fixtures.

• Chamber Calibration: Using a set of 4 SGHs (Standard Gain Horns) precision made by same contractors to NASA. Calibration continually verified using known standard antennas and other methods.
