The first point to consider when selecting EMF safety measurement equipment is the required frequency range.

It’s worth noting that with the addition of the Narda HP-01 (static / low frequency magnetic field analyser) firmware the Narda NBM-550 meter will support measurements from DC to 90 GHz. That’s quite a frequency range for one instrument and is unique in the world of EMF safety equipment. We’re not saying you need all of that frequency range all of the time as most assessments will be over a much narrower range but the beauty of a modular system supported by just one meter is that you can just add capability by buying probes as you need them. As system frequencies like 5G move upwards it's important that your measurement equipment has that high frequency capability.
