5.3 MEASUREMENT UNCERTAINTY
The following table is for the measurement uncertainty, which is calculated as per the
document CISPR 16-4-2.
PARAMETER
UNCERTAINTY
Semi Anechoic Chamber (966 Chamber_B) /
Radiated Emission, 30 to 1000 MHz
+/- 3.97
Semi Anechoic Chamber (966 Chamber_B) /
Radiated Emission, 1 to 18GHz
+/- 3.58
Semi Anechoic Chamber (966 Chamber_B) /
Radiated Emission, 18 to 26 GHz
+/- 3.59
Semi Anechoic Chamber (966 Chamber_B) /
Radiated Emission, 26 to 40 GHz
+/- 3.81
Conducted Emission (Mains Terminals),
9kHz to 30MHz
+/- 2.48
This uncertainty represents an expanded uncertainty expressed at approximately the
95% confidence level using a coverage factor of k=2.
Consistent with industry standard (e.g. CISPR 22, clause 11, Measurement Uncertainty)
determining compliance with the limits shall be base on the results of the compliance
measurement. Consequently the measure emissions being less than the maximum
allowed emission result in this be a compliant test or passing test.
The acceptable measurement uncertainty value without requiring revision of the
compliance statement is base on conducted and radiated emissions being less than
UCISPR which is 3.6dB and 5.2dB respectively. CCS values (called ULab in CISPR 16-4-2)
is less than UCISPR as shown in the table above. Therefore, MU need not be considered
for compliance.

The transmitter output was connected to a spectrum analyzer.
Set RBW = 100 kHz.
Set the video bandwidth (VBW) ≥ 3 x RBW.
Detector = Peak.
Trace mode = max hold.
Sweep = auto couple.
Allow the trace to stabilize.
Measure the maximum width of the emission that is constrained by the frequencies
associated with the two outermost amplitude points (upper and lower frequencies) that
are attenuated by 6 dB relative to the maximum level measured in the fundamental
emission.

7.3 AVERAGE OUTPUT POWER
LIMITS
§ 15.247(b) The maximum peak output power of the intentional radiator shall not exceed
the following:
§ 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.
§ 15.247(b) (4) Except as shown in paragraphs (c) of this section, if transmitting antennas
of directional gain greater than 6 dBi are used the peak output power from the intentional
radiator shall be reduced below the stated values in paragraphs (b)(1) or (b)(2), and (b)(3)
of this section, as appropriate, by the amount in dB that the directional gain of the antenna
exceeds 6 dBi.
§ KDB 662911:
If all antennas have the same gain, GANT, Directional gain = GANT + Array Gain, where
Array Gain is as follows.
If antenna gains are not equal, the user may use either of the following methods to
calculate directional gain, provided that each transmit antenna is driven by only one
spatial stream:
Directional gain may be calculated by using the formulas applicable to equal gain
antennas with GANT set equal to the gain of the antenna having the highest gain; or,

the intentional radiator to the antenna shall not greater than 8 dBm in any 3 kHz band

If all antennas have the same gain, GANT, Directional gain = GANT + Array Gain, where
Array Gain is as follows.
Array Gain = 10 log(NANT/NSS) dB.
If antenna gains are not equal, the user may use either of the following methods to
calculate directional gain, provided that each transmit antenna is driven by only one
spatial stream:
Directional gain may be calculated by using the formulas applicable to equal gain

Set analyzer center frequency to DTS channel center frequency.
Set the span to 1.5 times the DTS channel bandwidth.
Set the RBW to: 3 kHz ≤ RBW ≤ 100 kHz.
Set the VBW ≥ 3 x RBW.
Detector = peak.
Sweep time = auto couple.
Trace mode = max hold.
Allow trace to fully stabilize.
Use the peak marker function to determine the maximum amplitude level within the
RBW.

7.5 CONDUCTED SPURIOUS EMISSION
LIMITS
§ 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) (see §15.205(c)).

TEST SETUP
TEST PROCEDURE
The transmitter output is connected to a spectrum analyzer. The resolution bandwidth is
set to 100 kHz. The video bandwidth is set to 300 kHz.
The spectrum from 30 MHz to 26.5 GHz is investigated with the transmitter set to the
lowest, middle, and highest channels in the 2.4 GHz band.

TEST PROCEDURE
1. The EUT was placed on the top of a rotating table 0.8 and 1.5 meters above the
ground. The table was rotated 360 degrees to determine the position of the highest
radiation.
2. While measuring the radiated emission below 1GHz, the EUT was set 3 meters away
from the interference-receiving antenna, which was mounted on the top of a
variable-height antenna tower. While measuring the radiated emission above 1GHz,
the EUT was set 3 meters away from the interference-receiving antenna.
3. The antenna is a broadband antenna, and its height is varied from one meter to four
meters above the ground to determine the maximum value of the field strength. Both
horizontal and vertical polarization of the antenna are set to make the measurement.
4. For each suspected emission, the EUT was arranged to its worst case and then the
antenna was tuned to heights from 1 meter to 4 meters and the table was turned from
0 degrees to 360 degrees to find the maximum reading.
5. The test-receiver system was set to Peak Detect Function and Specified Bandwidth
with Maximum Hold mode.
6. If the emission level of the EUT in peak mode was 10 dB lower than the limit specified,
then testing could be stopped and the peak values of the EUT would be reported.
Otherwise the emissions that did not have 10 dB margin would be re-tested one by
one using peak, quasi-peak or average method as specified and then reported in a
data sheet.
Remark:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120 KHz for
Peak detection (PK) and Quasi-peak detection (QP) at frequency below 1GHz.
2. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 1 MHz for
Peak detection and frequency above 1GHz.
3. The resolution bandwidth of test receiver/spectrum analyzer is 1 MHz and the video bandwidth is
10 Hz for Average detection (AV) at frequency above 1GHz.

7.7 CONDUCTED EMISSION
LIMITS
§ 15.207 (a) Except as shown in paragraph (b) and (c) this section, for an intentional
radiator that is designed to be connected to the public utility (AC) power line, the radio
frequency voltage that is conducted back onto the AC power line on any frequency or
frequencies within the band 150 kHz to 30 MHz shall not exceed the limits in the following
table, as measured using a 50 µH/50 ohms line impedance stabilization network (LISN).
Compliance with the provisions of this paragraph shall be based on the measurement of
the radio frequency voltage between each power line and ground at the power terminal.
The lower limit applies at the boundary between the frequency ranges.

TEST PROCEDURE
The basic test procedure was in accordance with ANSI C63.10:2013.
The test procedure is performed in a 4m × 3m × 2.4m (L×W×H) shielded room.
The EUT along with its peripherals were placed on a 1.0m (W) × 1.5m (L) and 0.8m in
height wooden table and the EUT was adjusted to maintain a 0.4 meter space from a
vertical reference plane.
The EUT was connected to power mains through a line impedance stabilization network
(LISN) which provides 50 ohm coupling impedance for measuring instrument and the
chassis ground was bounded to the horizontal ground plane of shielded room. All
peripherals were connected to the second LISN and the chassis ground also bounded to
the horizontal ground plane of shielded room.
The EUT was located so that the distance between the boundary of the EUT and the
closest surface of the LISN is 0.8 m. Where a mains flexible cord was provided by the
manufacturer shall be 1 m long, or if in excess of 1 m, the excess cable was folded back
and forth as far as possible so as to form a bundle not exceeding 0.4 m in length.
