HFRA SF02G SCHWARZBECK Tunable Resonant Magnetic Field Ring Antenna

Introduction：

HFRA SF02G is a tunable resonant magnetic field loop antenna manufactured by Schwarzbeck (Germany) and distributed by EUTTEST (Shenzhen, China). This antenna is designed to generate very high field strengths in the frequency range of 10kHz-30MHz, and the antenna needs to be coupled with the HFRAE 5163 for controlling the strength of the magnetic field generated by this antenna.

Usage Profile:

Schwarzbeck has configured the SF02G antenna with a test software, HFRA SF02G Frequency control, which allows RF testers to send a test frequency value to the antenna.

To measure and control the field strength, the monitoring antenna HFRAE 5163 is mounted in the center of the SF02G antenna. This passively shielded magnetic field probe should be connected to an EMI test receiver. In order to calculate the magnetic field strength at the center of the transmitting antenna (dBμA/m), the magnetic antenna factor of the HFRAE 5163 must be added to the measured voltage level in dBμV.
