Introduction：
The HFRA 5152 is a magnetic field transmitter loop antenna manufactured by Schwarzbeck, Germany and distributed by EUTTEST, designed to generate a uniform magnetic field in the frequency range DC-3MHz. Tests require an external signal generator to be connected to the BNC input of the antenna, and the antenna is equipped with a second BNC monitoring connector that can be used with a high impedance voltmeter or oscilloscope to monitor the magnitude of the emitted RF level.
How to use:
This antenna can obtain the loop current from the voltage drop across the built-in 20 Ω resistor. For example, when the voltage at the monitoring connector is 50 mV, the loop current can be calculated to be 2.5 mA. In addition, the loop current of this antenna is proportional to the field strength generated by the antenna, and the output electric field strength is 0.01 V/m at a test distance of 1.3 meters, with a monitoring voltage of 50 mV. don't exceed the maximum value. . The maximum permissible monitoring voltage is 630 mV, beyond which the built-in resistor will be damaged and is not covered by warranty. For more information about the testing of this antenna, please contact our after-sales staff after purchasing.
