TEST PROCEDURE: ANSI Standard C63.4-2003 using a ANRITSU spectrum analyzer with a
pre-selector and an appropriate antenna. The resolution bandwidth of spectrum
analyzer was 100 kHz below 1 GHz and 1 MHz above 1 GHz. An appropriate sweep speed
was used. When an emission was found, the table was rotated to produce the maximum
signal strength. The antenna was placed in both the horizontal and vertical planes
and the worse case emissions were reported. The spectrum was searched to at least
the tenth (10) harmonic of the fundamental.
