Mobirise Website Builder

The VL001-0.9X0.9 is a pre-configured eight axes (3 motorized translational stage planar/spherical near-field measurement system ideal for measuring medium and high gain antennas (> 15 dBi) with aperatures up to 0.75 m (30 in.) from 2.6 GHz to mm Wave. The system is constructed of high strength aluminum and can support probe payloads of up to 6 kg (13 lb). This simple design is easy to assemble and align, accurate, and can be quickly dismantled for relocation or storage. 

Features

  • 2.0GHz to 43.5GHz
  • 110GHz to 300GHz (with mmw up/down converters)
  • Well suited for higher gain antennas (> 15 dBi)
  • Stationary AUT
  • Automatic scan setup
  • High speed bi-directional scanning
  • Powerful Plotting and Antenna Analysis Software
  • Far-field, Holographic and Near-field Patterns

Typical Applications

  • Point to Point Communication Antennas
  • Phased-Arrays
  • Reflector Antennas
  • Radar Antennas 

Capabilities

The VL001-0.9X0.9 supports Keysight, Anritsu and Rhode & Schwarz Vector Network Analyzer models and is capable of measuring amplitude and phase patterns from S-band to mmWave. The system includes a software workstation preloaded with WaveView™ Antenna Measurement Software and provides automatic calibration before measurement. Measured data can be processed for far-field and other or holographic patterns yielding complete characterization of the antenna’s performance. A single data set provides information on antenna gain, side lobe structure, beam pointing and cross polarization.

7-Axis Robotic Antenna Measurement System

VEL-001

Mobirise Website Builder

Velenova limited offer 7-axis Robotic Antenna Measurement System is ideal for measuring antenna scan size up to 2.5 m x 1.5 m. It is well suited to perform testing of high, medium and low gain antennas, since it offers Planar Near field scan and Spherical scan capabilities.

The 7-axis precision robotic arm that acts as PNF and Theta-axis for SNF. It allows SNF testing with adjustable probe radii and PNF testing with different AUT to probe separations. It also allows for PNF testing where the scan-plane can be arbitrary in rectangular shape allocated within the arm reachable distance. Its ideal for custom measurement application for high gain tiltable beam measurement . Measured data can be processed for far-field or holographic patterns yielding complete characterization of the antenna's performance. A single data set provides information on antenna gain, side lobe structure, beam pointing and cross polarization.

The system interfaces with a wide variety of RF equipment and is capable of measuring amplitude and phase patterns from low frequency-band to mmWave Bands.
