Utilizing cable data for the 233 cables, which was provided by one AMC cable manufacturer, the cables pitch diameter, pitch distance (lay length), and effective loop area (ELA) were calculated. Eight samples of various AMC cables were then tested utilizing a Helmholtz coil and a narrowband spectrum analyzer to determine their magnetic field susceptibility. A comparison was made with a selected number of MIL-C-915 cables to illustrate that, although the AMC cable typically has a reduced magnetic field susceptibility (due to its typically smaller ELA), its variable lay technique, designed to reduce high frequency crosstalk on many AMC cables, can actually make them more susceptible to low-frequency magnetic field pickup.
