The AL-RE101 is a receiving loop antenna used for Mil-Std 461, RE101 testing to measure the magnetic field intensity generated by the Equipment Under Test (EUT). Its construction consists of a 13.3 cm diameter, 36-turn, electrostatically shielded coil of 7-strand, 41 gauge Litz wire.
The base of the antenna is constructed from durable nylon, which is mounted over a plexi-glass plate. For convenience, the plate protrudes outward from the front of the antenna to provide the required 7 cm spacing between the center of the loop and the EUT, as shown in the diagram below.
The antenna output port is fitted with a high quality, female BNC connector for connection to the measuring instrument.
The electrostatic shield of the antenna is powder coated for additional durability.
The AL-RE101 Loop Antenna is specifically designed for tests according to MIL-STD-461, RE101, radiated emissions, magnetic field.
During this test, radiated emissions from the Equipment Under Test (EUT) are measured from equipment and subsystem enclosures, including electrical cable interfaces, to verify that the magnetic field emissions from the EUT and its associated electrical interfaces do not exceed the specified requirements.
The antenna is placed at a distance of 7 cm from the EUT face and electrical interface connector to be measured. The plane of the loop is oriented parallel to the EUT faces and parallel to the axis of the connectors.
The AL-RS101-TX is a transmitting loop antenna constructed with 20 turns of 12 gauge enamel-insulated copper wire with a mean diameter of 12 cm. The Teflon (PTFE) structure onto which the wire is wound is elongated in order to provide the required 5 cm spacing between the loop coils and the Equipment Under Test (EUT) when the antenna is placed flush against the EUT surface (please refer to AL-RS101-SET datasheet).
The AL-RS101-RX is a receiving loop antenna used during RS101 test level calibration to measure the magnetic field intensity generated by the AL-RS101-TX transmit loop.Its construction consists of a 51-turn, electrostatically shielded coil of 7-strand, 41 gauge Litz wire. The antenna output port is fitted with a female BNC connector.
