ANNEX A: Detailed Test Results

A.1. Measurement Method

A.1.1. Conducted Measurements

Connect the EUT to the test system as Fig.A.1.1.1 shows. Set the EUT to the required work mode. Set the EUT to the required channel. Set the Vector Signal Analyzer and start measurement. Record the values.

Diagram Description: The test setup diagram shows a connection from the EUT to an Attenuator, then to a Vector Signal Analyzer, all within a Shielding room.

A.1.2. Radiated Emission Measurements

The measurement is made according to ANSI C63.10. The radiated emission test is performed in a semi-anechoic chamber. The EUT was placed on a non-conductive table with 80cm above the ground plane for measurement below 1GHz and 1.5m above the ground plane for measurement above 1GHz. The measurement antenna was placed at a distance of 3 meters from the EUT. The test is carried out on both vertical and horizontal polarization, and only the maximization result of both polarizations is kept. During the test, the turntable is rotated from 0° to 360° and the measurement antenna is moved from 1m to 4m to get the maximization result. The maximization process was repeated with the EUT positioned in each of its three orthogonal orientations.

A.2. Maximum Output Power

Method of Measurement: See ANSI C63.10-2013-clause 11.9.1.3. The maximum peak conducted output power is measured using a broadband peak RF power meter with a video bandwidth greater than or equal to the DTS bandwidth and a fast-responding diode detector.

Measurement Limit: FCC CRF Part 15.247(b) < 30 dBm

A.2.1 Antenna Gain

Antenna gain is -1.14dBi, supplied by the applicant or manufacturer.

A.2.2. Peak Output Power-conducted
