Sample(s) Status

Engineer sample

Operation Frequency:

2408MHz~2475MHz

Channel numbers:

135

Modulation method: Modulation technology:

FHSS GMSK

Antenna Type:

Integral antenna

Antenna gain:

-1.11dBi(declare by applicant)

Power supply:

DC 6-13V(2-3S lithium battery)

Remark:

1. Antenna gain information provided by the customer

2. The relevant information of the sample is provided by the entrusting company, and the laboratory is not

responsible for its authenticity.

3. The system works in the frequency range of 2408MHz to 2475MHz. This band has been divided to 135

independent channels. Each radio system uses 16 different channels; the minimum channel separation is 4MHz.

By using various switch-on times, hopping scheme and channel frequencies, the system can guarantee a

jamming free radio transmission. Pre-testing all radio systems, this radio system recorded in the report is the

worst mode.The channel list is below.

The test frequencies are below: Channel

7.1 Antenna requirement
Standard requirement: FCC Part15 C Section 15.203 /247(c) 15.203 requirement: An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator, the manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. 15.247(c) (1)(i) requirement: (i) Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed. Point-to-point operations may employ transmitting antennas with directional gain greater than 6dBi provided the maximum conducted output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6dBi. EUT Antenna: The antenna is integral antenna, reference to the appendix II for details.

Test setup:

Test procedure:
Test Instruments: Test mode: Test environment: Test voltage: Test results:

1. The E.U.T and simulators are connected to the main power through a

line impedance stabilization network (L.I.S.N.). This provides a

50ohm/50uH coupling impedance for the measuring equipment.

2. The peripheral devices are also connected to the main power through a

LISN that provides a 50ohm/50uH coupling impedance with 50ohm

termination. (Please refer to the block diagram of the test setup and

photographs).

3. Both sides of A.C. line are checked for maximum conducted

interference. In order to find the maximum emission, the relative

positions of equipment and all of the interface cables must be changed

according to ANSI C63.10:2013 on conducted measurement.

Test Procedure:
Test Instruments: Test mode: Temp. / Hum. Test results:

1. The EUT was placed on the top of a rotating table (0.8 meters for below

1GHz and 1.5meters for above 1GHz) 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.

6. If the emission level of the EUT in peak mode was 10dB lower than the

limit specified, then testing could be stopped and the peak values of the

EUT would be reported. Otherwise the emissions that did not have 10dB

margin would be re-tested one by one using peak, quasi-peak or

average method as specified and then reported in a data sheet.
