A passive field probe for frequency selective measurements of the generated field according to EN 61000-4-3, including the measurement of the uniform area.
A further application is the validation of fully anechoic rooms for measurements above 1 GHz according the Site-VSWR-method, described in CISPR 16-1-4. In conjunction with the SBA 9112 a frequency range from 1 to 18 GHz can be covered with excellent antenna performance. Accepting some limitations (i.e. Antenna Factor and VSWR increase, symmetry reduction) the SBA 9119 can be used from 0.5 GHz on. The validation of test sites with commonly used Microwave antennas (e.g. Log.-Per. or Horn Antennas) leads to insufficient results, since these directive gain antennas with concentrated directional pattern do not take the test site characteristics into account.
Including transport case.
A mini version of the SBA 9119 Antenna is available upon request. Please contact us for further details.
