According to the KDB 558074 D01 v05 Subclause 8.4 and ANSI C63.10-2013 Subclause 11.10.3, such
specifications require that the same method as used to determine the conducted output power shall also be used to
determine the power spectral density. The test method of power spectral density as below:
a) Set instrument center frequency to DTS channel center frequency.
b) Set span to at least 1.5 times the OBW.
c) Set RBW to: 3 kHz ≤ RBW ≤ 100 kHz. .
d) Set VBW ≥3 x RBW.
e) Detector = power averaging (RMS) or sample detector (when RMS not available).
f) Ensure that the number of measurement points in the sweep ≥ 2 x span/RBW.
g) Sweep time = auto couple.
h) Employ trace averaging (RMS) mode over a minimum of 100 traces.
i) Use the peak marker function to determine the maximum amplitude level.
j) If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat (note that this may require
zooming in on the emission of interest and reducing the span in order to meet the minimum measurement point
requirement as the RBW is reduced).

7. RF Output Power
7.1 Standard Applicable
According to 15.247(b)(3). For systems using digital modulation in the 902–928 MHz, 2400–2483.5 MHz, and
5725–5850 MHz bands: 1 Watt.
7.2 Test Procedure
According to the KDB-558074 D01 v05 Subclause 8.3.2.2 and ANSI C63.10-2013 Subclause 11.9.2.2, when
this option is exercised, the measured power is to be referenced to the OBW rather than the DTS bandwidth
a) Set span to at least 1.5 times the OBW.
b) Set RBW = 1-5% of the OBW, not to exceed 1 MHz.
c) Set VBW ≥ 3 x RBW.
d) Number of points in sweep ≥ 2 × span / RBW. (This gives bin-to-bin spacing ≤ RBW/2, so that
narrowband signals are not lost between frequency bins.)
e) Sweep time = auto.
f) Detector = RMS (i.e., power averaging), if available. Otherwise, use sample detector mode.
g) If transmit duty cycle < 98 %, use a sweep trigger with the level set to enable triggering only on full power
pulses. The transmitter shall operate at maximum power control level for the entire duration of every
sweep. If the EUT transmits continuously (i.e., with no off intervals) or at duty cycle ≥ 98 %, and if
each transmission is entirely at the maximum power control level, then the trigger shall be set to “free
run”.
h) Trace average at least 100 traces in power averaging (i.e., RMS) mode.
i) Compute power by integrating the spectrum across the OBW of the signal using the instrument’s band
power measurement function, with band limits set equal to the OBW band edges. If the instrument does
not have a band power function, sum the spectrum levels (in power units) at intervals equal to the RBW
extending across the entire OBW of the spectrum.

8. Field Strength of Spurious Emissions
8.1 Standard Applicable
According to §15.247(d), in any 100 kHz bandwidth outside the frequency band in which the spread spectrum or
digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional
radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level
of the desired power, based on either an RF conducted or a radiated measurement, provided the transmitter
demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted
power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this
section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the
general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted
bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a).
The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The
provisions in §15.35 for limiting peak emissions apply. Spurious Radiated Emissions measurements starting
below or at the lowest crystal frequency.
8.2 Test Procedure
The setup of EUT is according with per ANSI C63.10-2013 measurement procedure. The specification used was
with the FCC Part 15.205 15.247(a) and FCC Part 15.209 Limit.
The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle.
The spacing between the peripherals was 10 cm.

8.3 Corrected Amplitude & Margin Calculation
The Corrected Amplitude is calculated by adding the Antenna Factor and the Cable Factor, and subtracting the
Amplifier Gain from the Amplitude reading. The basic equation is as follows:
Corr. Ampl. = Indicated Reading + Ant. Factor + Cable Loss – Ampl. Gain
The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit.
For example, a margin of -6dBV means the emission is 6dBV below the maximum limit. The equation for
margin calculation is as follows:
Margin = Corr. Ampl. – FCC Part 15 Limit
8.4 Summary of Test Results/Plots
Note: this EUT was tested in 3 orthogonal positions and the worst case position data was reported.
All test modes (different data rate and different modulation) are performed, but only the worst case is recorded in
this report.

9. Out of Band Emissions
9.1 Standard Applicable
According to §15.247 (d) In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or
digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional
radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level
of the desired power, based on either an RF conducted or a radiated measurement, provided the transmitter
demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted
power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this
section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the
general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted
bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a).
9.2 Test Procedure
According to the KDB 558074D01 v05 Subclause 8.4 and ANSI C63.10-2013 Subclause 11.11, the Emissions
in nonrestricted frequency bands test method as follows:
a) Set the center frequency and span to encompass frequency range to be measured.
b) Set the RBW = 100 kHz.
c) Set the VBW ≥ [3 × RBW].
d) Detector = peak.
e) Sweep time = auto couple.
f) Trace mode = max hold.
g) Allow trace to fully stabilize.
h) Use the peak marker function to determine the maximum amplitude level.
According to the KDB 558074 D01 v05 Subclause 8.5 and ANSI C63.10-2013 Subclause 11.12, the Emissions
in restricted frequency bands test method as follows:
A. Radiated emission measurements:
Set span = wide enough to capture the peak level of the emission operating on the channel closest to the bandedge,
as well as any modulation products which fall outside of the authorized band of operation (2310MHz to 2420MHz
for low bandedge, 2460MHz to 2500MHz for the high bandedge)
RBW = 1MHz, VBW = 1MHz for peak value measured
RBW = 1MHz, VBW = 10Hz for average value measured
Sweep = auto; Detector function = peak/average; Trace = max hold
All the trace to stabilize, set the marker on the emission at the bandedge, or on the highest modulation product
outside of the band, if this level is greater than that at the bandedge. Enable the marker-delta function, then use the
marker-to-peak function to move the marker to the peak of the in-band emission. Those emission must comply
with the 15.209 limit for fall in the restricted bands listed in section 15.205. Note that the method of measurement
KDB publication number: 913591 may be used for the radiated bandedge measurements.

FCC Part 15.247
Model: ZNCZ-MG02
B. Antenna-port conducted measurements
Peak emission levels are measured by setting the instrument as follows:
a) RBW = as specified in Table 9/
b) VBW ≥ [3 × RBW].
c) Detector = peak.
d) Sweep time = auto.
e) Trace mode = max hold.
f) Allow sweeps to continue until the trace stabilizes. (Note that the required measurement time may be
lengthened for low-duty-cycle applications.)
If the peak-detected amplitude can be shown to comply with the average limit, then it is not necessary to
perform a separate average measurement.
Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding
restricted frequency bands) are attenuated by at least the minimum requirements specified in section 8.1. Report
the three highest emissions relative to the limit.
