ELECTROMAGNETIC FIELD MONITOR
 

Smart Fieldmeter Electromagnetic (EM) field monitor combining the major features of professional quality field monitoring equipment with convenience and simplicity of the multimeter for users on a budget.
Multimode (Average, Peak and Pulse) operation allows monitoring of the sinusoidal and modulated fields by displaying the average or peak values together with fast response remote output that can be used for remote data analysis and close loop field control.
Portable lightweight design with long lasting battery and detachable isotropic probe offers advantages in the field, while tripod mounting of the probe and meter together with remote output monitoring benefits the EM field measurements in the laboratory setting.

Smart Fieldmeter can be used for evaluation and measurements of EM fields from various sources:

  • AM/FM/TV and Cellular stations.

  • Transmitters and CB radios.

  • Cell phones.

  • Microwave ovens.

  • Industrial, scientific and medical
    equipment.

  • Field monitoring in EMC test systems.

Specification:

  • Dynamic range: 0.2-600 V/m.

  • Linearity deviation: < 1.5 dB.

  • Isotropic probe.

  • Frequency range: 0.2MHz-3 GHz.

  • Modes: Average, Peak and Pulse. Auto zeroing.

  • NIST traceable certificate is supplied with every unit.

  • Warranty 1 year.

 SPECIFICATION
  • Portable EM field monitor with detachable isotropic probe.

  • Wide dynamic range: 0.2 - 600 V/m.

  • Broad frequency range: 0.2 MHz-3000 MHz.

  • Probe directivity: Omni directional (Isotropic probe).

  • Ranges (V/m, full scale): 2, 20, 200, 600.

  • Calibration accuracy: +/- 0.5 dB (at reference levels).

  • Linearity deviation: +/- 1.5 dB (any range 10-100% of full scale).

  • Probe frequency response: +/- 2.5 dB (0.5 MHz–3GHz), -3 dB @ 0.2MHz.

  • Probe isotropicity: +/- 1.5 dB (100, 500, and 2500 MHz).

  • Operating modes: Average, Pulse and Peak.

  • Reading: RMS (root mean square) normalized in all modes:
    Average:            RMS (Averaged over Tav).
    Pulse:               0.707 x Instant Value (Averaged over Tp).
    Peak:                0.707 x Peak Value (Averaged over Ts).

  • Response times for different operating modes:
    Average:           Tav (averaging time)=2 s.
    Pulse:              Tp (rise/fall time)=100 ms.
    Peak:               Ts (sample time) =100 ms, Th (hold time)=4 s.

  • Auto zeroing (automatic and/or user activated) operates even at strong EM
    fields, and eliminates temperature induced offset errors.

  • Display: LCD 3.5 Digits, with over-range feature.

  • Remote monitor: Special 1.8 m (6 ft.) cable (supplied with unit) allows remote
    output monitoring by data logger, scope or voltmeter.

  • Design: rugged dust-proof and splash proof hand held enclosure. Probe is
    mounted on nonmetal handle and can be removed for cable operation at a
    distance.

  • Standard tripod mount (1/4”-20) for meter, probe clip and nonmetal portable
    tripod are provided.
