EHP-50F Electric and Magnetic Field Analyser

Overview

Frequency selective FFT measuring system with high dynamic range for electric and magnetic fields from 1 Hz to 400 kHz. Sensors in all three spatial directions deliver isotropic results for selective and wideband measurements.

Uses the Weighted Peak method for standard-compliant measurement of complex signals. This method, patented by Narda, evaluates the signal by means of mathematical convolution in the time domain. The result is the direct display of the exposure as a percentage of the limit value. This makes the application particularly quick and easy to use.

Weighted Peak is the basis of the limit value curves of the most important standards.
