5.3 RADIATED EMISSION LIMIT

Class A Limit

Frequency Distance Field Strength

MHz Meter

dB(µV/m)

30 to 230 10 40

230 to 1000 10 47

Remark : 1. The tighter limit shall apply at the edge between two frequency bands.

2. Distance refers to the distance in meters between the measuring instrument antenna and the closed point of

any part of the device or system.

5.4 EUT CONFIGURATION

The equipment which is listed 3.4. are installed on Radiated Emission Test to meet the

Commission requirement and operating in a manner which tends to maximize its emission

characteristics in a normal application.

The device under test, installed in a representative system as described in section 5.2., was

placed on a non-conductive table whose total height equaled 80 cm. This table can be rotated

360 degree. The measurement antenna was mounted to a non-conductive mast capable of

moving the antenna vertically. Antenna height was varied from 1 meter to 4 meters and the

system under test was rotated from 0 degree through 360 degrees relative to the antenna

position and polarization (Horizontal and Vertical). Also the I/O cable position was investigated

to find the maximum emission condition.

5.5 OPERATING CONDITIONS OF THE EUT

Same as section 4.6.

5.6 RADIATED EMISSION DATA

The measurement range of radiated emission, which is from

30 MHz to 1 GHz,

was investigated.

All readings are quasi-peak values with a resolution Bandwidth of 120 KHz. The initial step in

collecting radiated emission data is a spectrum analyzer peak scans of the measurement range

for all the test modes and then use test receiver for final measurement. Then the worst modes

were reported the following data pages.
