Measurement of RF radiation patterns of EUTs
Key Facts The R&S®EMC32-K22 option expands the EMI auto test with the capacity to measure the RF radiation pattern and display it in a polar diagram. The existing EMC test system can thus be used also for antenna measurements. The option contains methods for measuring passive antennas and for measuring integrated antennas in mobile phones. In EMI measurements with peak detector, the EMI of the EUT can be spatially assigned, allowing targeted disturbance suppression.
Features & Benefits
  • Integrated measurement methods
    • Passive antennas
    • Integrated antennas in mobile phones
    • Assignment of disturbance
  • Recording RF radiation patterns To record the RF radiation patterns of an EUT in a plane, the EUT is rotated and the respective emission values are determined. To achieve the optimal test sequence, the test sequence order (frequency loop, turntable positions, polarization) can be individually defined by the user.
  • Determining the emission values Data is recorded as a series of individual measurements using a measuring receiver or spectrum analyzer. In the case of a spectrum analyzer, the Zero Span function is used.
  • Display as polar diagram During the measurement, the test results are displayed in a number of polar diagrams, for example one diagram per polarization. Each track in a diagram represents the measured level at the azimuth position. Different test frequencies are displayed in different tracks in a diagram.
