Narda NBM HF 0191 Overview
The Narda NBM HF 0191 H-Field probe, 27MHz - 1GHz contains three orthogonally arranged coils with detector diodes. The three voltages, corresponding to the spatial components, are available individually at the probe output. The NBM basic unit calculates the resulting isotropic field strength.
APPLICATIONS
The probe detects magnetic fields from 27 MHz to 1 GHz. This wide frequency range for a magnetic field probe covers all the major areas of electromagnetic field exposure that can occur in radio and TV broadcasting, telecommunications, and in high frequency industrial applications.

PROPERTIES
The probe is designed with mechanical and electrical properties ideal for field use. The probe head is made of foam material to provide effective protection for the sensors, while having excellent RF characteristics. The electric destruction limit is above 20 A/m for continuous wave signals, which is several times more than any of the human safety limit values.
