Overview
The probe contains three orthogonally arranged dipoles 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 electric fields from 100 kHz to 6 GHz, covering the fields that occur in broadcasting, telecoms, and industry. The high sensitivity of 0.2 V/m and wide frequency range make it ideal for new WLAN applications. In the frequency range of mobile phone base stations the probe exceeds the requirements of the latest basic standard EN
50492 and IEC 62232.
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.
CALIBRATION
The probe is calibrated at several frequencies. The correction values are stored in an EPROM in the probe and are automatically taken into account by the NBM instrument. Calibrated accuracy is thus obtained regardless of the combination of probe and instrument.
FEATURES
- Field exposure from broadcasting, telecoms and industrial equipment
- Measurements on base stations (EN 50492 and IEC 62232)
