Uses
For complex products with a radio element (i.e. Cordless and Cellular phones),
more sophisticated tests are required. This testing is not always covered
adequately by existing commercial facilities. These tests include testing of
transmitted electro-magnetic interference and the identification of spurious
signals.
The PDG RF screened anechoic chamber suppresses external background acoustic
noise as well as RF interference. This makes it ideal for certain acoustic
measurements, within the EMC free environment, essential to
the cordless telecommunications business.
If required for higher accuracy power, an RF power meter and/or a spectrum
analyser may be utilised to measure transmitted radiated power or EMC emissions.
The antenna can also be used to inject radiated signals into the chamber.
With the addition of a proprietary test generator, the signal generator can be
used to measure the receive sensitivity and selectivity or to produce RF
interference to test EMC susceptibility of non-radio products.
The PDG chamber can also detect what direction radio waves are being emitted
from. This is useful within the development stage, where alterations can be made
to have the waves emitted in a safer direction.
