3.6     Spurious Emission
LIMIT

According to §27.53 (h): For operations in the 1710–1755 MHz and 2110–2155 MHz bands, the power of any
emission outside a licensee’s frequency block shall be attenuated below the transmitter power (P) by at least
43 + 10 log10(P) dB.

TEST CONFIGURATION

                                        Conducted Spurious Measurement:




                                        Radiated Spurious Measurement:




TEST PROCEDURE

The EUT was setup according to EIA/TIA 603D

Conducted Spurious 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.
e. The resolution bandwidth of the spectrum analyzer was set sufficient scans were taken to show the out of
   band Emission if any up to10th harmonic.
f. Please refer to following tables for test antenna conducted emissions.

Radiated Spurious 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
   the frequency 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.
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. The resolution bandwidth of the spectrum analyzer was set at 100 kHz for Part 22 and 1MHz for Part 24.
   The frequency range was checked up to 10th harmonic.
r. Test site anechoic chamber refer to ANSI C63.

TEST RESULTS

Remark:
      1. We were tested all RB Configuration refer 3GPP TS136 521 for each Channel Bandwidth of LTE
         FDD Band 4; recorded worst case for each Channel Bandwidth of LTE FDD Band 4.

Radiated Measurement:

Remark:
1. We were tested all RB Configuration for the model L553 the Mode refer 3GPP TS136 521 for each
Channel Bandwidth of LTE FDD Band 4; recorded worst case for each Channel Bandwidth of LTE FDD Band
4
2. EIRP=PMea(dBm)-Pcl(dB) +Ga(dBi)
3. We were not recorded other points as values lower than limits.
4. Margin = Limit - EIRP

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 LTE band 4, 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.
