4.2 Test Mode
The EUT has been tested under its typical operating condition. Pre-defined engineering program for regulatory testing used to control the EUT for staying in continuous transmitting. Only the worst case data were reported.
The EUT has been associated with peripherals pursuant to ANSI C63.10-2013 and configuration operated in a manner tended to maximize its emission characteristics in a typical application. Frequency range investigated: radiation (9 KHz to the 10th harmonics of the highest fundamental frequency or to 40 GHz, whichever is lower).
The EUT has been tested under TX operating condition.
This EUT is a FHSS system, were conducted to determine the final configuration from all possible combinations. We use software control the EUT, Let EUT hopping on and transmit with highest power, all the modes GFSK, /4-DQPSK, 8DPSK have been tested. 79 Channels are provided by EUT. The 3 channels of lower, medium and higher were chosen for test.

7.4 Test Procedure
1. The testing follows the guidelines in Spurious Radiated Emissions of ANSI C63.10-2013. 2. Below 1000MHz, The EUT was placed on a turn table which is 0.8m above ground plane. And above
1000MHz, The EUT was placed on a styrofoam table which is 1.5m above ground plane. 3. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a
variable height antenna tower. 4. For each suspected emission, the EUT was arranged to its worst case and then tune the Antenna tower
(From 1m to 4m) and turntable (from 0 degree to 360 degree) to find the maximum reading. A pre-amp and a high pass filter are used for the test in order to get better signal level to comply with the guidelines. 5. Set to the maximum power setting and enable the EUT transmit continuously. 6. Final measurement (Above 1GHz): The frequency range will be divided into different sub ranges depending of the frequency range of the used horn antenna. The EMI Receiver set to peak and average mode and a resolution bandwidth of 1MHz. The measurement will be performed in horizontal and vertical polarization of the measuring antenna and while rotating the EUT in its vertical axis in the range of 0 degree to 360 degree in order to have the antenna inside the cone of radiation. 7. Test Procedure of measurement (For Above 1GHz): 1) Monitor the frequency range at horizontal polarization and move the antenna over all sides of the EUT(if necessary move the EUT to another orthogonal axis). 2) Change the antenna polarization and repeat 1) with vertical polarization. 3) Make a hardcopy of the spectrum. 4) Measure the frequency of the detected emissions with a lower span and resolution bandwidth to increase the accuracy and note the frequency value. 5) Change the analyser mode to Clear/ Write and found the cone of emission. 6) Rotate and move the EUT, so that the measuring distance can be enlarged to 3m and the antenna will be still inside the cone of emission. 7) Measure the level of the detected frequency with the correct resolution bandwidth, with the antenna polarization and azimuth and the peak and average detector, which causes the maximum emission. 8) Repeat steps 1) to 7) for the next antenna spot if the EUT is larger than the antenna beamwidth. 7. The radiation measurements are tested under 3-axes(X,Y,Z) position(X denotes lying on the table, Y denotes side stand and Z denotes vertical stand), After pre-test, It was found that the worse radiation emission was get at the X position. So the data shown was the X position only.

Test Standard Test Limit

FCC Part15 C Section 15.247 (a)(1) 0.4 sec

12.2 Test Setup

12.3 Test Procedure The EUT must have its hopping function enabled. Use the following spectrum analyzer settings: 1. Span= zero span, centered on a hopping channel 2. Set the RBW = 1 MHz. 3. Set the VBW = 3 MHz. 4. Sweep time = as necessary to capture the entire dwell time per hopping channel. 5. Detector function = peak. 6. Trace mode = max hold. 7. Allow trace to fully stabilize.

14 Antenna Requirement

14.1 Test Standard and Requirement

Test Standard FCC Part15 Section 15.203 /247(c) 1) 15.203 requirement:

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.

2) 15.247(c) (1)(i) requirement:

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 6 dBi.

14.2 Antenna Connected Construction

The antenna is Ceramic Antenna which permanently attached, and the best case gain of the antenna is 1.54 dBi. It complies with the standard requirement.
