Selective Field Analyzer SFA-G 30MHz -6GHz

Selective Field Analyzer SFA-G

Active broadband isotropic antenna combined with portable USB powered spectrum analyzer. OFA-G antenna has frequency response independent of antenna or electric field orientation. It offers broad dynamic range for the variety of RF regulatory, safety, EMC, wireless and telecommunications applications. Spectrum analyzer SA-S/J displays the frequencies and field strength of selected signals, allowing all results to be viewed and stored on PC.

USB SA Screen 1 OFA-G with USB SA In hand 2

Omnifield Antenna® OFA-G, consists of antenna head with handle and detachable power unit PU-5G. Antenna head has 3 antennas positioned normal to each other. Signals from each antenna are combined to allow output signal to be proportional to the absolute value of the field regardless of the field direction. Power unit contains gain stage, rechargeable battery and connectors for the antenna and output cable.

SA-S Picture

Spectrum Analyzer SA-S/J is equipped with powerful RF signal processing software, preprogrammed with OFA-G antenna factors, allowing the display of the measurement data in natural field strength or power density units.

There are two variants of spectrum analyzer, having different frequency range: SA-S (1 Hz-4.4GHz) and SA-J (100 KHz-12.4 GHz).

Calibration Details: Isotropic Antennas Calibration

  • • Calibration: Every antenna, cable and power module calibrated together with 5 feet cable and SA-S/J spectrum analyzer for AF.  UK NPL traceable Calibration Certificate is supplied with each unit.
  • 1) Antenna Factors (AF) at specified frequencies in the frequency range 30 MHz-6000 MHz (@ 5 V/m)
  • 2) Antenna Rotational isotropicity.
  • 3) For Selective Spectrum Analyzer we provide a memory card with AF data.

– Keep unit calibrated. We recommend calibration once a year in our NIST traceable EMC Test Lab.

.

– To convert the electric field strength E (V/m) into power density S (uW/cm2) use formula: S=E2/3.77. To calculate the value of the magnetic field H (far field region) use the relationship: E/H=377 Ohm.
