Electric Field Probes
An E-field probe measures the true field strength in an anechoic chamber. Additionally, an E-field probe is used to calibrate the anechoic chamber, the importance of the instrument’s measurement capabilities should not be underestimated. In order to make such accurate field strength measurements, the size and shape as well as the number of measuring elements of an E-field probe are important parameters. Raditeq has optimized these parameters and added patented technology in order to achieve the best accuracy on the market.

Committed to continuous improvement
Since then, the Raditeq development team has been continuously improving its product, the application of the spherical shaped probe proves just that.
Continuous improvement requires constant research. Raditeq built its own special e-field test room to research the isotropic behaviour of e-field probes. Staggering results presented that the isotropic behaviour of e-field probes available on the market are far more inferior than expected. The RadiSense 6, by no means the worst probe, was no exception. Using the knowledge gained from numerous measurements, our team took on the challenge of building a probe with better isotropic behavior.
At the beginning of 2020, this resulted in the RadiSense® 10, the probe with the best isotropic behavior available in the market.
Convince yourself and measure the difference!
Since 1999, Raditeq has been developing a series of Electric Field Probes named RadiSense®. Conventional E-field probes are known to be battery powered and therefore take up more space. The invention of the RadiSense® laser powered E-field probe hence redefined the limits of probe power supply. The compact shape resulted not only in better accuracy but made 24/7 testing available. The RadiSense® has made its predecessors obsolete when considering uptime and convenience.
Additionally, the RadiSense® 10 is inherently small, making it perfect for (G) TEM cell measurements. For measurements in (G) TEM cells, the size of the probe is even more important. If compact cells are used, substantial errors will occur with an E-field probe that is relatively large to the dimensions of the cell. To obtain reliable and accurate measurement results, the EMC probe must be small, isotropic and fast. The RadiSense® 10 offers all these aspects and is therefore the most reliable choice for an E-field probe.
Internal calibration data
By default, the factory linearity adjustment data is stored inside the probe. In addition, the frequency response correction data for all three axis, which is obtained from an accredited calibration laboratory, can be stored inside the probe as user correction. Due to this internal correction, there is no need to apply frequency dependent corrections for individual axis’ in software anymore. This results in a high accuracy and ease-of-use.
Did you know?
LASER is an abbreviation which stands for for “Light Amplification of Stimulated Emission of Radiation”. Over time the abbreviation has become so well known that it turned into a noun. This is why LASER is written as Laser or laser.
Available RadiSense® Models
RadiSense® 10 series
Our latest range of the most accurate electric field probes on the market. These probes have a very low isotropic error. The RadiSense® 10 range encompasses four different models each with qualities intended for specific applications.
Battery powered probes present many disadvantages as opposed to laser powered probes, these include; influence of galvanic wires on measured E-field, battery drainage and limited overnight testing. Unlike other probes, the RadiSense® E-field probe is powered by a high-performance laser, whose light is sent to the probe via a fiber optic cable and feeds the low-noise amplifier and a single microprocessor chip, reads the antennas and transmits the measured values to a PC via a second fiber optic cable.
A small electric field probe is essential for measurements in a uniform field of an anechoic chamber. In the past it was commonly agreed upon that smaller probes provide for more accurate measurement. controversially, later findings show that the position of the probe is of equal importance to the accuracy and reliability of the measurement. When the probe rotates in the anechoic chamber, the measurements will vary and may present values that differ considerably to those that are actually present. Needless to say that this process is detrimental to the final data.
The RadiSense® 10 offers the perfect solution to this problem. With six antenna elements, this probe offers an unprecedented isotropic response. Regardless of its position or its angle, the radiation and its reflections reach the probe.
The RadiSense® E-field strength sensors are supported by RadiMation®, the automated EMC measurement software. The RadiMation® Free software is included with the system for stand-alone use. The RadiSense® can also be controlled by third party software as all control codes are available.
Importance of accurate measurement
During immunity testing, the accuracy of the overall test setup depends solely on the E-field probe. As such, accuracy mainly determined by isotropy, is of the utmost importance. Over the years, Raditeq’s development team has been committed to developing probes with increasing accuracy.
The RadiSense® Series can be operated by the RadiMation® software with which you can use your Electric Field Probe with ease. Next to RadiMation® the RadiSense® 10 can be used with EMC32 Software. You can find the needed configuration and format specification here.
