EFD-4091 FieldMan E-Field probe, 2MHz - 40GHz

EFD-4091

Isotropic measurement of electric fields from 2 MHz to 40 GHz using the Field Meter FieldMan®

Kuvaus

The probe detects electric fields from 2 MHz up to 40 GHz. This area covers the frequencies used for broadcasting, as well as applications for telecommunications, satellite communications and radar technologies. The probe’s high linearity and sensitivity make it ideal for checking human safety limit values in the general public and occupational environments. 

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. Probe calibration is carried out at several frequencies and is accredited up to 18 GHz. 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.

  • Isotropic (non-directional) measurement
  • Excellent sensitivity starting at 1.2 V/m
  • Wide True RMS range up to 65 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
  • Wide temperature range from -20 °C to +50 °C
  • Calibration is performed up to 40 GHz and is accredited up to 18 GHz
