RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Pfullingen, June 1, 2015 – Narda Safety Test Solutions has launched a new FFT analyzer for low frequency electromagnetic fields. This device, called EHP-50F, measures and analyzes electric and magnetic field strengths in the frequency range 1 Hz to 400 kHz and evaluates the results in accordance with current human safety standards.
The EHP-50F from Narda Safety Test Solutions is a new FFT analyzer for assessing low frequency electric and magnetic fields considering aspects of human safety. It covers the entire range from 1 Hz to 400 kHz that is relevant for sensory effects. It evaluates complex signal shapes in the time domain using the weighted peak method, which is specified in the latest standards such as the EMF Directive 2013/35/EU. The device provides automatic frequency evaluations complying with 2013/35/EU for all the specified action levels as well as with ICNIRP 2010 and ICNIRP 1998 (General Public and Occupational).
The EHP-50F uses built-in three-axis probes to detect electric and magnetic fields isotropically (non-directionally). It is battery operated, making it suitable for stand alone operation for up to 24 hours with internal data. It can be connected to the Narda NBM-550 HF measuring set, which acts as a control and display unit, by an optical cable, which does not affect the field being measured. This can also be used for connection to a PC for further evaluation and documentation of the measurement results. The PC software is included in the package.
EHP-50F is available as of now.
