Laboratory Testing

Antenna Performance Verification

Many antenna manufacturers do not follow a common standard when designing, during the production process, or when compiling supporting documentation. R-Spectrum's antenna testing service is an impartial consultation that enables clients to conduct a side-by-side comparison of the actual performance of antennas that is independent from manufacturer supplied datasheets.

Laboratory testing of antennas and ancillary RF components is conducted within parameters set by the company's quality management system. This guarantees that accurate results detailing the performance are gathered and the subsequent test reports compiled can be presented with confidence to our clients. Reliable side-by-side comparisons allow our clients to make well informed procurement decisions.

Regardless of how technologically advanced a network is, wireless performs only as well as the antennas that have been integrated.

  • 4500 mᶾ microwave anechoic chamber
  • RTS65 microwave reverberation dark room
  • Five microwave shield rooms
  • Vehicle test site
  • Near and far field (1 km) testing systems
  • 3D (SG64 probe) testing systems
  • >100 Keysight Technology advanced test equipment
  • Intermodulation Distortion (IMD) test systems
  • Laser Diode Vibrometer (LDV) testing systems
  • Five-frequency intermodulation test equipment
  • Five-frequency power test equipment
  • Static interference test equipment
  • Low + high temperature and humidity testing systems

  • Ultraviolet light testing systems
  • Waterproof testing systems
  • RoHS environmental testing equipment

Antenna test reports are tailored to clients’ needs. It may be unnecessary to engage engineers to perform testing on redundant performance characteristics and examining only the relevant fields greatly reduces the costs involved. Targeted testing also ensures that critical parameters attract the appropriate level of attention. In the case of IoT and telemetry applications an operator may have assigned a very narrow band for uplink and downlink and therefore it is important that testing is focused at these frequencies.
