EFD-9091 FieldMan E-Field probe, 100MHz - 90GHz

EFD-9091

Isotropic measurement of electric fields from 100 MHz to 90 GHz using the Field Meter FieldMan®

Description

The probe detects electric fields from 100 MHz up to 90 GHz. This area covers the frequencies used for radio link, 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 0.5 V/m
  • Wide True RMS range up to 61.4 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
