3. Conducted Emission Test

3.1. Test Standard and Limit

Remark: (1) *Decreasing linearly with the frequency. (2) The lower limit shall apply at the transition frequency.

3.2. Test Setup

A diagram shows a shielding room with a table. On the table, the EUT is connected to an Auxiliary Equipment (AE) via AC Line using LISN1 and LISN2. A Test Receiver is also present. The setup is 0.8m high and 1.5m from the LISN. A Ground Reference Plane is indicated.

3.3. Test Procedure

The EUT system 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. Both sides of AC line 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 FCC ANSI C63.10: 2020 on Conducted Emission Measurement. The bandwidth of test receiver (ESCI) set at 9kHz. The frequency range from 150kHz to 30MHz is checked.

3.4. Test Data

During the test, pre-scan all modes, only the worst case is recorded in the report. AC conducted emission pre-test at both AC 120V/60Hz and AC 240V/60Hz modes, recorded worst case AC 120V/60Hz. Please refer to the following pages.

4.1. Test Standard and Limit

Remark:

1. (1)The lower limit shall apply at the transition frequency.
2. (2) 15.35(b), Unless otherwise specified, the limit on peak radio frequency emissions is 20dB above the maximum permitted average emission limit applicable to the equipment under test. This peak limit applies to the total peak emission level radiated by the device.

4.2. Test Setup

Below 30MHz Setup: A diagram shows a metal full soldered ground plane with the EUT and a system simulator. The setup is 80cm high. A spectrum analyzer/receiver is connected to an RX antenna (1m height).

30MHz to 1GHz Setup: A diagram shows a metal full soldered ground plane with the EUT and a system simulator. The setup is 80cm high. A spectrum analyzer/receiver is connected to an RX antenna (1m height). The distance between EUT and antenna is 3m.

Above 1GHz Setup: A diagram shows a metal full soldered ground plane with the EUT and a system simulator. The setup is 1.5m high. A spectrum analyzer/receiver is connected to an RX antenna (1-4m height). The distance between EUT and antenna is 3m.

4.3. Test Procedure

For below 1GHz: The EUT is placed on a turntable, which is 0.8m above the ground plane.

For above 1GHz: The EUT is placed on a turntable, which is 1.5m above the ground plane.

The turn table can rotate 360 degrees to determine the position of the maximum emission level. The EUT is set 3 meters away from the receiving antenna which is mounted on an antenna tower. The antenna can be moved up and down from 1 to 4 meters to find out the maximum emission level. Rotated the EUT through three orthogonal axes to determine the maximum emissions, both horizontal and vertical polarization of the antenna are set on test. The EUT is tested in 9*6*6 Chamber. The device is evaluated in xyz orientation.

4.4. Test Data

During the test, Pre-scan all kind of the plot mode (X-axis, Y-axis, Z-axis), and found the X-axis is the worst case.

The test results of 9kHz-30MHz was attenuated more than 20dB below the permissible limits, so the results don't record in the report.

During the test, pre-scan all modes, only the worst case is recorded in the report.

7. Allow trace to fully stabilize.
8. Use peak marker function to determine the peak amplitude level.

5.4. Test Data

Note: For pre-scan, the result is less than and equal to original, so the original data is referenced.

6. Antenna Requirement

6.1. Test Standard and Requirement

FCC Part15 Section 15.203 / 247(c)

1) 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.

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.
