Abstract
Measurement of the E field component of a RF electromagnetic field at a single point using electric field probes is well understood. However, using a single probe to measure the E field at a number of points in space is time consuming and the results are at different actual times. A multiple probe array may be considered in order to achieve a 'snapshot' measurement of all test points concurrently but, since each probe itself distorts the field, measurement error is introduced. This error has been investigated by experimental and modelling techniques, using a range of field scattering bodies and antennas, to determine if it can be limited sufficiently to make the use of multiple probes viable.
