Antenna Testing and Certification

Pre-compliance testing can be defined as the preliminary evaluation of a device for certification. It is the best way to identify if a device underlines a potential possibility to meet all relevant certifications. Especially for devices using Bluetooth or WLAN, early testing benefits the addressing of potential performance faults before they manifest themselves. Conducting the tests as early into a project as possible aids in the avoidance of delay or costly redesign elements of the product to enable effective performance.

• The Total Radiated Power (TRP)
  TRP is an active measure of how much power is radiated in all directions by an antenna when connected to an actual radio transmitter. It is measured in an anechoic chamber with a testing system.

• The Radiated Spurious Emissions (RSE)
  An RSE test is an important required test item for the 3GPP standard and the FCC’s North American standard certifications. It evaluates uncontained (radiated) electromagnetic waves, which often appear as signals in frequency. Erroneous frequencies are a waste of energy.

• The Specific Absorption Rate (SAR)
  A SAR test explains how much RF energy is absorbed by the human body or head when using handheld devices. Or shows the absorption of material near an antenna, such as the housing materials.
