1.0 Introduction
The ETS-Lindgren Model 3162 Series Field Generating Pyramidal Horn was
developed to meet the following specifications for automotive EMC component
testing:
 GMW3097 (3164-01)
 ES-XW7T-1A278-AC (3164-01, 3164-02)
These tests require that the Equipment Under Test (EUT) be exposed to a
pulsed peak field level of 600 V/m at a distance of 100 cm from the front of the
horn when the EUT is placed on a metallic top test bench. At these frequencies it
is difficult and expensive to find amplifiers with high power ratings; and because
of near field gain compression, most horns fail to meet this specification at the
required test distance unless power in excess of 800 W is used. The
Model 3162 Series optimizes near field behavior, and produces a field level of
600 V/m with a 500 W amplifier.
