Quality

The Easat range of antennas, pedestals and ancillary equipment is manufactured and tested in facilities audited to BS EN ISO 9001:2008.

Production Tests

Inspection is carried out during all stages of production to ensure compliance with the design quality procedures.

Together with general engineering test equipment, Easat has also developed a range of specialised equipment utilised to measure reflector surfaces.

Operational Testing

To ensure satisfactory operation in service, preliminary run tests are carried out on all equipments prior to factory acceptance testing.

Mechanical Factory Acceptance Tests

Prior to despatch, all equipment is tested to factory acceptance procedure and is witnessed by either the customer or an Easat QA representative.

RF Testing

Each major RF component is checked to ensure compliance with the requirements before it is assembled on the antenna. The checks include critical parameters such as:

  • Input VSWR and insertion loss for reflector feeds sub-array components.
  • Waveguide lengths and amplitude ratios for polarisation switching networks.
  • Phase linearity for sub-array assemblies.

These tests are performed at Easat's own laboratory, which is equipped to carry out the measurement of small to medium sized RF components.

Every antenna manufactured by Easat is normally subjected to RF testing in an independent, ISO 9001-accredited antenna test facility.

The antenna pattern is measured in the near-field and the results are transformed to the far-field; this process gives more accurate results than far-field measurement alone, and is also capable of providing pattern cuts at various points in space, should the customer require this.
