| Testing & Quality
Quality Assured
The Easat range of antennas, pedestals
and ancillary equipment is manufactured and tested in facilities
audited to BS EN ISO 9001-2000.
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 are
tested to a factory acceptance procedure and are either witnessed
by the customer or 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 mediumsized 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
and is also capable of providing pattern cuts at various points
in space, should the customer require this.
