Easy way to detailed analyses

It is as user-friendly as broadband devices, but has detailed analysis tools such as spectrum analyzers including displays: Field strength, power density or percent of limit.

Standard-compliant measurement

The SRM evaluates according to ICNIRP and national and international standards with an exact display in percent in relation to the permissible limit value - time-saving and reliable directly in the device.

Measuring antennas for every requirement

Different antennas are available for your specific requirements - for electric and magnetic fields from long wave to the latest generation of mobile communications.

Quick to measure, without alignment

The isotropic antennas detect the field strength independently of direction, with concentric sensors in the X, Y and Z axes; the SRM calculates the resulting field strength automatically.

Use time-saving routines

With the help of programmable measurement routines, setups and automatic settings, recurring measurement sequences can be prepared - for reproducible results and fewer incorrect settings.

Fixed and precise safety assessment

The frequency-selective measurement records mobile radio channels from different operators separately. Worst-case evaluations are also possible by decoding the respective signal structures.

Handy, efficient and suitable for outdoor

The SRM is irradiation-proof up to 200 V/m, robust and splash-proof. Replaceable batteries, GPS and voice recorder facilitate measurements on site. However, its features are just as impressive in the laboratory.

5G code-selective measurements

With the 5G NR option, you can perform a code-selective EMF measurement of 5G signals in frequency range 1 (FR1) - at any time without the operator's on-site involvement.

SRM antennas for specific applications

5G FR2 antenna

The E-field antenna from 24.25 GHz to 29.5 GHz extends the SRM-3006 for the frequency range 2 (FR 2) of 5G NR. It is optionally available with a horn or directional or omnidirectional characteristic.

SRM - triaxial antennas

The use of a triaxial (isotropic) antenna facilitates positioning and therefore also the use of the measuring device. The antenna detects fields from all directions and sums them in the correct phase. The triaxial (isotropic) E-field antenna from 200 MHz to 6 GHz (or 27 MHz to 3 GHz) is ideal for fast, direction-independent measurements in the latest mobile radio and wireless technologies.

The triaxial (isotropic) H-field antenna from 9 kHz to 250 MHz was developed for fast, non-directional near-field measurements of the magnetic field at radio/TV transmitters and industrial plants.

SRM single-axis antennas

Single-axis antennas can process the recorded field strengths very quickly. In contrast to a three-axis (isotropic) antenna, the individual axes of a single-axis antenna do not have to be connected in series. The faster scanning time can bring significant advantages, especially with pulsed signals. The special design also offers higher precision and better sensitivity during measurement.

The uniaxial H-field antenna from 9 kHz to 300 MHz and uniaxial E-field antenna from 9 kHz to 300 MHz are ideal for precise near-field measurements on radio and TV transmitters as well as industrial systems.

The uniaxial (single-axis) E-field antenna from 27 MHz to 3 GHz is ideal for precision measurements in the mobile radio sector.
