TEST PROCEDURE
1. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter camber. The
table was rotated 360 degrees to determine the position of the highest radiation.
2. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top
of a variable-height antenna tower.
3. The antenna height is varied from one meter to four meters above the ground to determine the maximum
value of the field strength. Both horizontal and vertical polarizations of the antenna are set to make the
measurement.
4. For each suspected emission, the EUT was arranged to its worst case and then the antenna was tuned
to heights from 1 meter to 4 meters and the rota table was turned from 0 degrees to 360 degrees to find
the maximum reading.
5. The test-receiver system was set to Peak Detect Function and Specified Bandwidth with Maximum Hold
Mode.
