Narda: Standards-compliant EMF measurement solutions from 0 Hz to 90 GHz – planning security for the

Standards-compliant EMF measurement solutions (for electrical and magnetic fields) from Narda STS ensure customers are fully equipped for the future – including 5G. With outstanding flexibility and suitable for virtually all applications – especially in the frequency range above 6 GHz – users of the NBM-550 field strength meter can enjoy the benefits of tomorrow’s advanced technology today.

New additions to the range of products for Narda’s rugged broadband field meters (NBM) include the EF 4091 (40 MHz to 40 GHz) and EF 9091 (100 MHz to 90 GHz) electrical field probes for the measurement of field strengths in the highest frequency and millimeter 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 0 Hz (DC) to 1 kHz and completes the portfolio at the lowest end of the spectrum. The newly developed magnetic field probe offers a high dynamic range of 120 dB and is thus highly recommended for use in occupational health and safety applications. It is ideal 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 10 µT to 10 T (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 700 MHz to 86 GHz. The SRM-3006 even permits selective measurements of individual services up to 6 GHz. However, the highest bit rates of up to 10 Gbit/s, promised for the next generation of mobile communications, will primarily be achieved in the “high band” above 6 GHz as this offers greater bandwidth. The 26 GHz band, in particular, and the various bands in the millimeter spectrum between 31 and 86 GHz 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 90 GHz 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.
