shall apply (see clause 2.5.1.3).
The test conditions are set out in
Annex A in QCVN 18:2014/BTTTT and the provisions in clauses 2.3.2 to 2.3.5 of
the present document.
Whenever the EUT is provided with a
detachable antenna, the EUT shall be tested with the antenna fitted in a manner
typical of normal intended use, unless specified otherwise.
2.3.2.1.
Arrangements for test signals for GSM and DCS
The provisions of QCVN
18:2014/BTTTT, A.2 shall apply with the following modifications given in
clauses 2.3.2.1.1 to 2.3.2.1.3.
2.3.2.1.1.
GSM and DCS Arrangements for establishing a communications link
The nominal frequency of the wanted
RF input signal (for the receivers) shall be selected by setting the Absolute
Radio Frequency Channel Number (ARFCN) to an appropriate number (e.g. in case
of GSM 900 MHz this is 60 to 65, and in case of GSM 1 800 MHz this is 690 to
706).

When the EUT is required to be in
the transmit/receive mode, the following conditions shall be met:
- the EUT shall be commanded to operate at maximum transmit
power;
- the downlink RXQUAL shall be monitored.
2.3.2.1.2.
GSM and DCS Calibration of the overall audio link performance
Prior to the test sequence, the
reference level of the speech output signal on both the downlink and uplink
shall be recorded on the test instrumentation, as shown in figure 1.
If the equipment does not include
acoustical transducers (e.g. a microphone or loudspeaker) the equivalent
electrical reference levels shall be specified
by the manufacturer.
The voice processor may often apply
noise and echo cancellation algorithms which attempt to eliminate or reduce steady state audio signals as e.g. the 1 kHz calibration signals.
The calibration should be carried
out with the noise and echo cancellation algorithms disabled.
If the noise and echo cancellation
algorithms cannot be disabled then the reference level of the speech output
signal should be measured using a max-hold detection on the audio level meter
in order to determine the level before the noise and echo cancellation
algorithms become effective.

- The EUT is not used for the calibration of the downlink. Adjust
the output of the audio test source to achieve a reference level equivalent to
a SPL of 0 dBPa at 1 kHz at the input of the acoustic coupler for the downlink.
Record the reading of the audio level meter as the reference level.
- If in handsfree applications an external loudspeaker is used,
the SPL from the external loudspeaker is higher
than
that from the earpiece of the portable by a certain amount in order to overcome
a high ambient noise level. Two methods can be used to achieve the required
SPL:
+ the
downlink reference level shall be increased by the same amount in order to
compensate for the difference
in SPL; or
+ the
distance between the loudspeaker and the measuring microphone shall be adjusted
during the measurement procedure.
Calibration of the uplink:
- For the calibration of the uplink the EUT is used. Adjust the
output of the audio test source to achieve a reference level equivalent to a
SPL of -5 dBPa at 1 kHz at the Mouth Reference Point (MRP) defined in
Recommendation ITU-T P.64. Record the reading of the audio level meter, which
is connected to the output of
the test system, as the reference level.
- For handsfree applications, normally no corrections are made to
the uplink reference level. If it is not possible to perform the above
calibration, the manufacturer shall
specify the distance between the
MRP and the microphone.

The voice processor may apply noise
and echo cancellation algorithms which attempt to eliminate or reduce steady
state audio signals as e.g. the 1 kHz calibration signals.
When the audio levels are measured
during testing the EUT software shall be configured for voice applications. If
the algorithms for noise and echo cancellation are not disabled, then the level
shall be measured using a max-hold detection on the audio level meter in order
to determine the level before the noise and echo cancellation algorithms become
effective.
Set the EUT volume to provide the
nominal audio level if specified by the manufacturer. If no such level is
specified, the centre volume step shall be
used. The volume settings shall be recorded in the test report.
The level of the output signal from
the downlink speech channel of the EUT at the mobile or portable's earpiece
shall be assessed by measuring the Sound Pressure Level (SPL) as shown in
figure 2. When an external loudspeaker is used the acoustic coupler shall be
fixed to the loudspeaker in the position used during the calibration.
The level of the decoded output
signal from the uplink speech channel of the EUT at the analogue output of the
test system shall be measured. Pick up of extraneous background noise by the
microphone of the EUT shall be minimized by sealing
the speech input port (microphone) of the EUT (see figure 2).
If the equipment is designed for
use with external transducers, they shall be included in the test
configuration. If the equipment does not include acoustical transducers the
line voltage developed across a specified termination impedance may be
measured.

Responses on receivers or duplex
transceivers occurring during the test at discrete frequencies which are narrow
band responses (spurious responses), are identified by the following method
(the procedure below only applies if the separation between test frequencies
exceeds 500 kHz):
-
if during an immunity test the RXQUAL or speech output signal
level being monitored goes outside the specified figure, it is necessary to
establish whether the RXQUAL increase or speech output signal level increase is
due to a narrow band response or to a wide band phenomenon. Therefore,
the test shall be repeated with the unwanted signal frequency increased, and
then decreased by 400 kHz;
-
if the RXQUAL increase or speech output signal level increase
disappears in either or both of the above 400 kHz offset cases, then the
response is considered as a narrow band response;
-
if the RXQUAL increase or speech output signal level increase does
not disappear, this may be due to the fact that the offset has made the
frequency of the unwanted signal correspond to the frequency of another narrow
band response. Under these circumstances the procedure is repeated with the
increase and decrease of the frequency of the unwanted signal set to 500 kHz;

unwanted effect on the receiver of the UE or on the test system (narrow band
response) or to a wideband (EMC) phenomenon. Therefore, the test shall be
repeated with the UARFCN increased or decreased by:
+ FDD bands

Set the EUT
volume to provide the nominal audio level if specified by the manufacturer. If no such
level is specified, the centre volume step shall be used.
Prior to
the test sequence, the reference level of the speech output signal on both the
downlink and uplink shall be recorded on the test instrumentation, as shown in
figure A.1. The reference level shall be equivalent to the SPL of 0 dBPa at 1
kHz at the input of the acoustical coupler described ETR 027 for the
downlink, and -5 dBPa at 1 kHz at the mouth reference point (MRP) defined in
Recommendation ITU-T P.64 for the uplink.
NOTE 1: The MRP is
defined with respect to an artificial head defined in Recommendation ITU-T
P.76. The handset should be mounted on the artificial head such that the ear
piece is centred at the artificial ear.
NOTE 2: If the
equipment does not include acoustical transducers (e.g. a microphone or
loudspeaker) the manufacturer should specify the equivalent electrical
reference levels.
The voice
processor may often apply noise and echo cancellation algorithms, which attempt
to eliminate or reduce steady state audio signals as e.g. the 1 kHz calibration
signals. These algorithms may be disabled during the calibration procedure. Specialized
test software may be required. If the algorithms cannot be
disabled then the reference level shall be measured using a max-hold detection
on the audio level meter in order to determine the level before the noise and
echo cancellation algorithms become effective.
Normally no
corrections are made to the uplink reference level. The manufacturer shall
specify the distance between the MRP and the microphone.
Figure A.1.
Audio
breakthrough measurement, calibration set-up for portable equipment
NOTE: The EUT is in position
during calibration of the uplink, but not during calibration of the downlink
where the EUT is replaced by the 1 kHz test audio source. During calibration of
the uplink the mouthpiece shall be placed with respect to the MRP in a way representing intended use.

When the
audio levels are measured during testing the EUT software shall be configured
for voice applications. If the algorithms for noise and echo cancellation are not
disabled, then the level shall be measured using a max-hold detection on the
audio level meter in order to determine the level before the noise and echo
cancellation algorithms become effective.
The level
of the output signal from the downlink speech channel of the EUT at the mobile
or portable's ear piece shall be assessed by measuring the Sound Pressure Level
(SPL) as shown in figure A.2. When an external loudspeaker is used the
acoustical coupler shall be fixed to the loudspeaker in the position used
during the calibration. The level of the decoded output signal from the uplink speech
channel of the EUT at the analogue output of the test system shall be measured. Pick up of
extraneous background noise by the microphone of the EUT shall be minimized.
NOTE: If the
equipment is designed for use with external transducers, they should be
included in the test configuration. If the equipment does not
include acoustical transducers the line voltage developed across specified
termination impedance may be measured.

B.1.2. E-UTRA
For the EUT, calibration of the
data transfer may be performed by assessing the throughput percentage before
applying the RF immunity test signal.
B.2. Assessment
of data transfer
B.2.1. UTRA.
Derivation of Error Ratios
The manufacturer shall provide the
method for calculating the Error Ratio. Known data patterns shall be
transferred bi-directionally from end-to-end (the whole of the UL and DL will
be exercised). Performance assessment shall be made at each frequency step. Comparison
between transmitted known data and received data shall result in the Error
Ratio.
The data patterns used should be of
sufficient length to give valid results and should be equivalent to the used
channel bit rate.
Possible data patterns for
assessing the Error Ratio are BER, BLER and User Data. Detailed description of
BER and BLER can be found from ETSI TS 134 109.
End-User Data may be used where BER
and BLER measurements are not appropriate and is a manufacturer's decision.
EXAMPLE: In the
cases when the EUT consists of UE with data application ancillary and the data
application ancillary itself does not support a loopback function that can be
applied for the assessment of BER or BLER, as specified in ETSI TS 134 109. This would
lead into a situation where the data application ancillary is not exercised,
i.e. the data transfer loop is not end-to-end.

B.3. EUT without data application ancillary
Data
monitoring Devices are here considered as part of the Test System. Arrangements
should be made by the manufacturer, if needed, to couple the Data monitoring
Device by a method which does not affect the radiated electromagnetic field
(e.g. ultrasonic or optical).
