Isotropic Probe

The probe for the NBM series of wideband field strength meters can be used for safety measurements on the electric fields emanating from transmitting equipment, covering the entire range from long wave up to the latest generation of mobile phone base station frequencies. With its frequency range from 100kHz to 6GHz, the probe detects the high frequency electric fields output by radio and TV transmitters, telecommunications equipment, and industrial installations. The dynamic range covers 65dB without any need to switch measurement ranges when used with the NBM basic unit. The sensitivity of 0.35V/m means that fields emanating from WLAN and WiMAX installations can be measured reliably. The probe exceeds the requirements of EN 50492 for safety assessments of mobile phone base stations and is ready for the forthcoming IEC 62232 standard. The probe is isotropic, which means it gives the correct measurement regardless of the direction of the field.
