Introduction：
The HFRA 5155 is a calibration device manufactured by Schwarzbeck in Germany and authorized for sale by EUTTEST in Shenzhen.Passive Magnetic Field TX Launch Loop AntennaThe antenna consists of a 50 mm diameter shielded single coil with a broadband transformer inside the antenna to achieve a flat frequency response curve and is designed to generate small to medium magnetic fields in the frequency range of 100 kHz to 300 MHz. The antenna is also equipped with a monitoring connector which is connected to a 10 kΩ voltage probe to monitor the antenna voltage during the test.
Monitor connector impedance curve > 10kΩ
