EFD-0391 FieldMan E-Field probe, 100kHz - 3GHz

EFD-0391
Narda Safety Test Solutions

Isotropic measurement of electric fields from 100kHz to 6GHz using the Field Meter FieldMan®

Aprašymas

The probe detects electric fields from 100 kHz to 3 GHz, covering the fields that occur in broadcasting, telecoms, and industry. The high sensitivity of 0.2 V/m and excellent linearity make it ideal for measuring human safety limit values in the general public domain.

The probe's interface digitally transmits the measurement data to the base unit, which has no individual influence on the measured values and therefore does not need to be calibrated. The accredited probe calibration is carried out at several frequencies. The calibration data is stored in the probe and is automatically taken into account during the measurement. If the frequency of the predominating field strength is known, a correction factor can additionally be applied to increase the measurement accuracy.

  • General public and occupational field exposure from broadcasting, telecoms and industrial equipment
  • Isotropic (non-directional) measurement
  • 64 dB dynamic without changing range
  • Excellent sensitivity starting at 0.2 V/m
  • Digital probe interface - no more meter calibration
  • Self-test of the probe interface with integrated sensor function test
  • Automatic offset correction, no zero adjustment required
  • Temperature compensation of the sensors for minimum drift and wide temperature range down to -20 °C
  • High Immunity at 50/60 Hz
  • Accredited calibration included
