EMF measurement devices are future-proofed

New additions to the range of products for Narda’s rugged broadband field meters (NBM) include the EF 4091 (40MHz to 40GHz) and EF 9091 (100MHz to 90GHz) electrical field probes for the measurement of field strengths in the highest frequency and millimetre wave bands. In early November 2017, these were joined by the HP-01 magnetometer – Narda’s new isotropic probe for the lowest frequency band. This provides frequency-selective analysis of static and time-variable magnetic fields from 0Hz (DC) to 1kHz and completes the portfolio at the lowest end of the spectrum.

The newly developed magnetic field probe offers a high dynamic range of 120dB and is thus highly recommended for use in occupational health and safety applications. It is suitable for evaluating field exposures in manufacturing industry workplaces with high static magnetic fields in accordance with the European Directive 2013/35/EU. The HP-01 incorporates non-directional Hall effect sensors that cover an extremely wide measurement range from 10μT to 10T (Tesla - magnetic flux density) in a single device. The instrument can be controlled using the HP01-TS PC software solution (supplied) and from mid-2018 also via the NBM-550. Typical applications include safety measurements in the areas of electromobility, electrolysis, magnetic stirrers, permanent magnets and magnetic resonance tomography (MRT) as well as DC motors and generators.

This high level of planning security for the future also includes 5G mobile communications as Narda already covers all frequency bands from 700MHz to 86GHz. The SRM-3006 even permits selective measurements of individual services up to 6GHz. However, the highest bit rates of up to 10Gbit/s, promised for next-gen mobile communications, will primarily be achieved in the 'high band' above 6GHz as this offers greater bandwidth.

The 26GHz band, in particular, and the various bands in the millimetre spectrum between 31-86GHz will be used here for data transmission. Extensive testing will be essential because the complexity and technical challenges of mobile telecommunication systems and equipment increase rapidly for manufacturers as the frequency band rises.

Although the first 2/5 test installations have already been built, the testing phase for 5G will really begin in 2018. Those users who choose the NBM with 90GHz probe from Narda are sure to be wellequipped for all eventualities over the coming years. As a manufacturer of measurement instruments, Narda STS currently offers products for all 5G systems including the highest frequencies – and this at an extremely early stage in the testing phase for these services.
