1.0 Introduction The ETS-Lindgren 6500 Series Loop Antennas include both active and passive antennas. Loop antennas provide a wide range of magnetic field testing. Some models include active electronics for amplification and impedance matching, consistent linear antenna factors, and signal attenuation. Most include a balanced Faraday shield to reduce response to E-fields for pure magnetic field measurements.
Model 6502 The Model 6502 Loop Antenna is an active receiving loop antenna designed to perform commercial emissions standards testing, and can be used for any magnetic testing. The Model 6502 has a frequency range of 9 kHz to 30 MHz. A radio frequency preamplifier is built into the base of the antenna and provides a 50 Ω...
Model 6507 The Model 6507 Loop Antenna is an active receiving loop antenna designed to perform shielding effectiveness measurements per MIL-STD 285 and NSA-65-6 specifications. The Model 6507 has a frequency range of 1 kHz to 30 MHz. A radio frequency preamplifier is built into the base of the antenna designed for use with most 50 Ω...
Model 6509 When using the Model 6509 as a transmitting device, reduce amplifier power to zero Watts before band switching. The Model 6509 Passive Loop Antenna is designed for shielding effectiveness and immunity testing. The Model 6509 operates in the frequency range of 1 kHz to 30 MHz.
Standard Configuration Antenna/coil assembly Mounting base that accepts an ETS-Lindgren tripod or other tripod mount with standard 1/4–20 threaded hardware Battery charger (included only with Model 6502 and Model 6507) Optional Items ARRYING ASES A custom carrying case is available for some of the loop antenna models. For more information, contact ETS-Lindgren.
7-TR Tripod—Constructed of PVC and fiberglass components, providing increased stability for physically large antennas. The unique design allows for quick assembly, disassembly, and convenient storage. Allows several different configurations, including options for manual or pneumatic polarization. Quick height adjustment and locking wheels provide ease of use during testing.
2.0 Maintenance Before performing any maintenance, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. Maintenance of the 6500 Loop Antennas WARRANTY is limited to external components such as cables or connectors. Warranty may be void if the housing is opened.
Replacement and Optional Parts ETS-Lindgren may substitute a similar part or new part number with the same functionality for another part/part number. Contact ETS-Lindgren for questions about part numbers and ordering parts. Following are the part numbers for ordering replacement or optional parts for the Model 6500 Series Loop Antennas.

5.0 Operation Before connecting any components or placing into operation, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. When using the Model 6509 as a transmitting device: Reduce amplifier power to zero watts before band switching, and then select the frequency band by rotating the band switch.
Battery Charger: Models 6502 and 6507 The Model 6502 and Model 6507 are powered by two 6-VDC, sealed lead-acid batteries. The included battery charger is intended for charging only the sealed lead-acid batteries in ETS-Lindgren products. The charger included may be PN 102615 or 1719587. The Model 6502 is not designed to operate using the battery charger as a power source.
Power cord—To maintain safety requirements, use the safety-approved power cord provided. If you use another method to attach the battery charger to the power mains, use only a type HD21 (PVC cord) or type HD22 (rubber cord) with a nominal cross-section of 0.75 mm –...

7.0 Radiation Pattern The 6500 Series Loop Antennas are electrically small loops (size is small in wavelengths), giving them identically-shaped radiation patterns. Each loop operates at a frequency under 30 MHz. At 30 Hz the wavelength is 10 m; the largest loops have a circumference of 1.88 m (C=πD), which is much smaller than the wavelength.
Typical Radiated Pattern for an Electrically Small Loop The following illustrates the typical radiated pattern for an electrically small loop. Radiation Pattern www.ets-lindgren.com...

11. Adjust signal amplitude on signal generator to maximum allowed by amplifier input. Establish a reference level by decreasing the attenuation level unit the signal can be detected by the screen room wall between them. Reduce attenuation further until signal is again seen at the same level as without shielding.
