3.1. Limit

Intentional radiators operating under the alternative provisions to the general emission limits, as contained in FCC part 15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated.

3.2. Test Procedure

The transmitter output was directly connected to a spectrum analyzer with a 50 Ω cable. The bandwidth of the fundamental frequency was measured by spectrum analyzer with 3KHz RBW and 10kHz VBW. The 20dB bandwidth is defined as the total spectrum the power of which is higher than peak power minus 20dB.

3.3. Test Setup

4. Radiated Emissions

4.1. Limit

The following table specifies the field strength limits for radiated emissions at a 3-meter measurement distance:

Note:

• a) The tighter limit applies at the band edges. For example: F.S limit at 88MHz is 100uV/m.
• b) If measurement is made at 3m distance, then F.S Limit at 3m distance is adjusted by using the formula of Ld1 = Ld2 * (d2/d1)². For example: F.S Limit at 30m(d2) distance is 30uV/m(Ld2), then F.S Limit at 3m(d1) distance is Ld1 = 30uV/m * (30/3)² = 100 * 30uV/m = 69.54 dBuV/m.
• (a) The field strength of any emissions within the band 13.553-13.567 MHz shall not exceed 15,848 microvolts/meter at 30 meters.
• (b) Within the bands 13.410-13.553 MHz and 13.567-13.710 MHz, the field strength of any emissions shall not exceed 334 microvolts/meter at 30 meters.
• (c) Within the bands 13.110-13.410 MHz and 13.710-14.010 MHz the field strength of any emissions shall not exceed 106 microvolts/meter at 30 meters.
• (d) The field strength of any emissions appearing outside of the 13.110-14.010 MHz band shall not exceed the general radiated emission limits in §15.209.

4.2. Block Diagram of Test Setup

Page 11 / 27

4.3. Test Procedure

Procedure of Preliminary Test:

1. The EUT and Support equipment, if needed, were placed on a non-metallic table, 80cm above the ground plane.
2. The EUT configuration was set up to simulate typical usage as described in clause 2.4, and test equipment as described in clause 4.2 of this report was used.
3. All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10:2013.
4. Mains cables, telephone lines, or other connections to auxiliary equipment located outside the test area shall drape to the floor, be fitted with ferrite clamps or ferrite tubes placed on the floor at the point where the cable reaches the floor, and then routed to the place where they leave the turntable. No extension cords shall be used to the mains receptacle.
5. The antenna was placed at 3 meters away from the EUT as stated in ANSI C63.10:2013. The antenna was connected to the Spectrum Analyzer via a cable, and at times a pre-amplifier would be used.
6. The Receiver quickly scanned from 9KHz to 30MHz and 30MHz to 1GHz. The EUT test program was started. Emissions were scanned and measured by rotating the EUT 360 degrees and positioning the antenna 1 to 4 meters above the ground plane, in both the vertical and the horizontal polarization, to maximize the emission reading level.
7. The test mode(s) described in clause 2.4 were scanned during the preliminary test.
8. After the preliminary scan, the test mode producing the highest emission level was identified. The EUT and cable configuration, antenna position, polarization, and turntable position for this highest emission level were recorded for the final test.

Procedure of Final Test:

1. The EUT and support equipment were set up on the turntable as per the configuration with the highest emission level found in the preliminary test.
2. The Receiver scanned from 9KHz to 30MHz and 30MHz to 1GHz. Emissions were scanned and measured by rotating the EUT to 360 degrees, varying cable placement, and positioning the antenna 1 to 4 meters above the ground plane, in both the vertical and the horizontal polarization, to maximize the emission reading level.

Diagram for 30MHz-1GHz: The test setup is depicted within a 'Semi-Anechoic 3m Chamber'. The 'EUT' is placed on a 'Turn Table (Wood)' at a distance of 3.0m from the antenna. The antenna's elevation varies from 1 to 4m. Ancillary equipment includes an 'AMP', 'Receiver', and 'PC System', all connected appropriately.

4.4. Test Result

The test results indicate PASS for radiated emissions from 9KHz to 30MHz. The test data of the worst-case condition(s) was recorded. The bandwidth of the test receiver was set at 200Hz for 9 KHz to 150 KHz, 10 KHz for 150 KHz to 30MHz, and 120 KHz for 30 MHz to 1GHz.

From 9KHz to 30MHz: Conclusion: PASS

Frequency Range: 9KHz~30MHz

Test Mode: TX: 13.56MHz

Test Results: PASS

Notes:

1. The test results are listed in the following pages.
2. This mode is the worst-case mode, so this report only reflects the worst mode.
3. If the limits for the measurement with the average detector are met when using a receiver with a peak detector, the test unit shall be deemed to meet both limits, and the measurement with the quasi-peak detector need not be carried out.
