5.3.Configuration of EUT on Measurement
The following equipment are installed on the Conducted Emission Measurement to meet
the commission requirements and operating regulations in a manner which tends to
maximize its emission characteristics in normal application.
5.3.1.Bluetooth Laser Mouse (EUT)
Model Number : DS-2292(2292-B)
Serial Number : N/A
Manufacturer : Eastern Times Technology Co., Ltd.

5.4.Operating Condition of EUT
5.4.1.Setup the EUT and simulator as shown as Section 5.1.

5.4.2.Turn on the power of all equipment.

5.4.3.Let the EUT work in Connect to PC mode measure it.

5.5.Test Procedure
The EUT is put on the plane 0.8m high above the ground by insulating support and is
connected to the power mains through a line impedance stabilization network (L.I.S.N.).
This provides a 50ohm coupling impedance for the EUT system. Please refer the block
diagram of the test setup and photographs. Both sides of AC lines are checked to find out
the maximum conducted emission. In order to find the maximum emission levels, the
relative positions of equipment and all of the interface cables shall be changed according
to ANSI C63.4: 2003 on Conducted Emission Measurement.

The bandwidth of test receiver (R & S ESCS30) is set at 9kHz.

The frequency range from 150kHz to 30MHz is checked.

6.5.Test Procedure
The EUT and its simulators are placed on a turntable, which is 0.8 meter high above
ground. The turntable can rotate 360 degrees to determine the position of the maximum
emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted
on an antenna tower. The antenna can be moved up and down between 1.0 meter and 4
meters to find out the maximum emission level. Broadband antenna (calibrated bilog
antenna) is used as receiving antenna. Both horizontal and vertical polarizations of the
antenna are set on measurement. In order to find the maximum emission levels, all of the
interface cables must be manipulated according to ANSI C63.4: 2003 on radiated
emission measurement.

The bandwidth of test receiver is set at 120kHz in 30-1000MHz.

The frequency range from 30MHz to 1000MHz is checked.

The final measurement for frequencies below 1000MHz is performed with Quasi Peak
detector.

The spectral diagrams are attached as below display the measurement of peak values.

Note:
1. Emissions attenuated more than 20 dB below the permissible value are not reported.
2. The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss, and subtracting
the amplifier gain(if any)from the measured reading. The basic equation calculation is as follows:
Result = Reading + Corrected Factor
Where Corrected Factor = Antenna Factor + Cable Loss + High Pass Filter Loss – Amplifier Gain
