Introduction - ETS-Lindgren 6502 User Manual

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. Whether used individually or as a set, the loop antennas provide
an efficient and economical solution to magnetic field measurement.
For information on Model 6505 Shielding Effectiveness Test Kit, see
page 37.
Each antenna is individually calibrated in accordance with the IEEE Std 291,
using National Institute of Standards and Technology (NIST) traceable
equipment. By knowing the actual antenna factors and performance
characteristics instead of typical data, you can more accurately measure field
strength in your tests. Each antenna includes actual individual calibration factors
and signed Certificate of Calibration Conformance.
All loop antennas are constructed of lightweight aluminum, which provides
durability and reliability for years of trouble-free indoor and outdoor services. The
base of each loop antenna provides a standard 1/4–20 threaded connector for
mounting to an ETS-Lindgren tripod or other tripod. For the variety of mounting
options available, see Mounting Instructions on page 19.
