EFD-5091 FieldMan E-Field anturi, 300MHz - 50GHz

EFD-5091

Isotropic measurement of electric fields from 300 MHz to 50 GHz using the Field Meter FieldMan®

Kuvaus

The probe contains three orthogonally-arranged thermo-couple sensors and detects electric fields from 300 MHz to 50 GHz, covering the fields found in telecommunications, satellite communications and radar equipment. The use of thermocouples naturally results in a true RMS reading, making the probe particularly suitable for measuring human safety limit values in a multi-frequency environment.

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.

  • Measurement of field exposure from telecommunications, satellite communications and radar in working environments
  • True RMS value display even when several, strongly pulsed signals are superimposed
  • Isotropic (non-directional) measurement
  • 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
  • Lowest temperature response due to thermocouple sensor technology and wide temperature range down to -20 °C
  • High Immunity at 50/60 Hz
  • Accredited calibration included
