1.4   Statement of the measurement uncertainty
The data and results referenced in this document are true and accurate. The reader is cautioned that there
may be errors within the calibration limits of the equipment and facilities. The measurement uncertainty was
calculated for all measurements listed in this test report acc. to CISPR 16 - 4 „Specification for radio
disturbance and immunity measuring apparatus and methods – Part 4: Uncertainty in EMC
Measurements“ and is documented in the Shenzhen HUAK Testing Technology Co., Ltd.quality system acc.
to DIN EN ISO/IEC 17025. Furthermore, component and process variability of devices similar to that tested
may result in additional deviation. The manufacturer has the sole responsibility of continued compliance of
the device.

Hereafter the best measurement capability for Shenzhen HUAK Testing Technology Co., Ltd.is reported:

3 TEST CONDITIONS AND RESULTS
3.1     Output Power
LIMIT

During the process of testing, the EUT was controlled via R&S Digital Radio Communication tester (CMW500)
to ensure max power transmission and proper modulation. This result contains output power and EIRP
measurements for the EUT. In all cases, output power is within the specified limits.

TEST CONFIGURATION

                                     Conducted Power Measurement




                                          Radiated Power Measurement:




TEST PROCEDURE

The EUT was setup according to EIA/TIA 603D

Conducted Power Measurement:
a) Place the EUT on a bench and set it in transmitting mode.
b) Connect a low loss RF cable from the antenna port to a spectrum analyzer and CMW500 by a Directional
   Couple.
c) EUT Communicate with CMW500, then select a channel for testing.
d) Add a correction factor to the display of spectrum, and then test.

Radiated Power Measurement:
a. The EUT shall be placed at the specified height on a support, and in the position closest to normal use as
   declared by provider.
b. The test antenna shall be oriented initially for vertical polarization and shall be chosen to correspond to
   thefrequency of the transmitter
c. The output of the test antenna shall be connected to the measuring receiver.
d. The transmitter shall be switched on and the measuring receiver shall be tuned to the frequency of the
    transmitter under test.
e. The test antenna shall be raised and lowered through the specified range of height until a maximum signal
   level is detected by the measuring receiver.


                                                     Page 9 of 18              Report No.: HK1902130277-4E

f.    The transmitter shall then be rotated through 360°in the horizontal plane, until the maximum signal level
      is detected by the measuring receiver.
g.    The test antenna shall be raised and lowered again through the specified range of height until a maximum
      signal level is detected by the measuring receiver.
h.    The maximum signal level detected by the measuring receiver shall be noted.
i.    The transmitter shall be replaced by a substitution antenna.
j.    The substitution antenna shall be orientated for vertical polarization and the length of the substitution
      antenna shall be adjusted to correspond to the frequency of the transmitter.
k.    The substitution antenna shall be connected to a calibrated signal generator.
l.    If necessary, the input attenuator setting of the measuring receiver shall be adjusted in order to increase
      the sensitivity of the measuring receiver.
m.    The test antenna shall be raised and lowered through the specified range of height to ensure that the
      maximum signal is received.
n.    The input signal to the substitution antenna shall be adjusted to the level that produces a level detected by
      the measuring receiver, that is equal to the level noted while the transmitter radiated power was measured,
      corrected for the change of input attenuator setting of the measuring receiver.
o.    The measurement shall be repeated with the test antenna and the substitution antenna orientated for
      horizontal polarization.
p.    The measure of the effective radiated power is the larger of the two levels recorded at the input to the
      substitution antenna, corrected for gain of the substitution antenna if necessary.
q.    Test site anechoic chamber refer to ANSI C63.4.

3.3     Peak-to-Average Ratio (PAR)

LIMIT

The Peak-to-Average Ratio (PAR) of the transmission may not exceed 13 dB.

TEST CONFIGURATION




TEST PROCEDURE

      1. Refer to instrument’s analyzer instruction manual for details on how to use the power statistics/CCDF
         function;
      2. Set resolution/measurement bandwidth ≥ signal’s occupied bandwidth;
      3. Set the number of counts to a value that stabilizes the measured CCDF curve;
      4. Set the measurement interval as follows:
         1). for continuous transmissions, set to 1 ms,
         2). for burst transmissions, employ an external trigger that is synchronized with the EUT burst timing
         sequence, or use the internal burst trigger with a trigger level that allows the burst to stabilize and set
         the measurement interval to a time that is less than or equal to the burst duration.
      5. Record the maximum PAPR level associated with a probability of 0.1%.

3.4     Occupied Bandwidth and Emission Bandwidth
LIMIT

N/A

TEST CONFIGURATION




TEST PROCEDURE

The transmitter output was connected to a calibrated coaxial cable and coupler, the other end of which was
connected to a spectrum analyzer. The occupied bandwidth was measured with the spectrum analyzer at low,
middle and high channel in each band. The -26dBc Emission bandwidth was also measured and recorded.
Set RBW was set to about 1% of emission BW, VBW≥3 times RBW.
-26dBc display line was placed on the screen (or 99% bandwidth), the occupied bandwidth is the delta
frequency between the two points where the display line intersects the signal trace.

TEST PROCEDURE

1. The transmitter output port was connected to base station.
2. The RF output of EUT was connected to the power meter by RF cable and attenuator, the path loss was
   compensated to the results for each measurement.
3. Set EUT at maximum power through base station.
4. Select lowest and highest channels for each band and different modulation.
5. Measure Band edge using RMS (Average) detector by spectrum

3.7     Frequency Stability under Temperature & Voltage Variations
LIMIT

According to §27.54, §2.1055 requirement, the frequency stability shall be sufficient to ensure that the
fundamental emissions stay within the authorized bands of operation and should not exceed 2.5ppm.

TEST CONFIGURATION




TEST PROCEDURE

The EUT was setup according to EIA/TIA 603D

Frequency Stability Under Temperature Variations:
In order to measure the carrier frequency under the condition of AFC lock, it is necessary to make
measurements with the EUT in a “call mode”. This is accomplished with the use of R&S CMW500 DIGITAL
RADIO COMMUNICATION TESTER.
1. Measure the carrier frequency at room temperature.
2. Subject the EUT to overnight soak at -30℃.
3. With the EUT, powered via nominal voltage, connected to the CMW500 and in a simulated call on middle
channel for NB-IoT eFDD 13, measure the carrier frequency. These measurements should be made within 2
minutes of Powering up the EUT, to prevent significant self-warming.
4. Repeat the above measurements at 10℃ increments from -30℃ to +50℃. Allow at least 1.5 hours at each
temperature, unpowered, before making measurements.
5. Re-measure carrier frequency at room temperature with nominal voltage. Vary supply voltage from
minimum voltage to maximum voltage, in 0.1Volt increments re-measuring carrier frequency at each voltage.
Pause at nominal voltage for 1.5 hours unpowered, to allow any self-heating to stabilize, before continuing.
6. Subject the EUT to overnight soak at +50℃.
7. With the EUT, powered via nominal voltage, connected to the CMW500 and in a simulated call on the
centre channel, measure the carrier frequency. These measurements should be made within 2 minutes of
Powering up the EUT, to prevent significant self-warming.
8. Repeat the above measurements at 10 ℃ increments from +50℃ to -30℃. Allow at least 1.5 hours at each
temperature, unpowered, before making measurements
9. At all temperature levels hold the temperature to +/- 0.5℃ during the measurement procedure.
Frequency Stability Under Voltage Variations:
Set chamber temperature to 20℃. Use a variable AC power supply / DC power source to power the EUT and
set the voltage to rated voltage. Set the spectrum analyzer RBW low enough to obtain the desired frequency
resolution and recorded the frequency.
Reduce the input voltage to specify extreme voltage variation (±15%) and endpoint, record the maximum
frequency change.
