3162-02 Field Generating Antenna

​ETS-Lindgren's Model 3162-02 Field Generating Pyramidal High Gain Horn​​ was specifically developed for the ES-XW7T-1A278- AC specification for radar pulse testing.​ ​​This test requires that the EUT be exposed to a pulsed peak field level of 600 V/m at a distance of 100 cm (39.37 in) from the front of the horn. Because of near field gain compression, most horns fail to meet this specification at the required test distance. The Model 3162-02 optimizes the near field behavior to overcome this problem, and produces a field level of 600 V/m with input power of less than 300 W. The Model 3162-02 is a pyramidal horn antenna with nominal dimensions of 70.1 cm L x 30.7 cm W x 36.6 cm H (27.6 in x ​12.1 in x 14.4 in) and has extended ground planes with chokes for better gain on each side​.
