2.3.1. General
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. Arrangements for test signals
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).
A communication link shall be set up with a suitable base station simulator (hereafter called "the test system").
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.
Calibration of the downlink:
- 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.

Figure 1. Audio breakthrough measurement, calibration set-up for portable equipment
2.3.2.1.3. GSM and DCS Measurement of the audio level at the speech output of the EUT
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.

Figure 2: Audio breakthrough measurement, test set-up for portable equipment
2.3.2.2. Arrangements for test signals for CDMA Direct Spread (UTRA and E-UTRA)
The provisions of QCVN 18:2014/BTTTT, A.2 shall apply with the following modifications:
- The wanted RF signal nominal frequency shall be selected by setting the UTRA or E-UTRA Absolute Radio Frequency Channel Number (UARFCN or EARFCN) to an appropriate number;
- A communication link shall be set up with a suitable base station simulator (hereafter called "the test system"). The test system shall be located outside of the test environment;
- Where possible the test of the transmitter section and receiver section of the EUT may be carried out simultaneously to reduce test time.
Immunity tests shall be performed in two modes of operation:
- with a communication link established (traffic mode); and
- in the idle mode.
When the EUT is required to be in the traffic mode, a call is set up according to the Generic call set-up procedure and the following conditions shall be met:
- set and send continuously Up power control commands to the UE;
- the DTX shall be disabled;
- Inner Loop or Up Link Power Control shall be enabled;
- for UTRA the transmitting and/or receiving (UL/DL) bit rate for reference test channel shall be 12,2 kbit/s. E-UTRA the transmitting and/or receiving (UL/DL) bit rate for reference test channel shall be the reference measurement channel as specified in Annex C in ETSI TS 136 101 with parameters specified in tables 7.3.1-1 and 7.3.1-2 in ETSI TS 136 101;
- For UTRA see ETSI TS 134 108 and ETSI TS 134 109 Logical Test Interface for details regarding generic call set-up procedure and BER, BLER test loop scenarios; for E-UTRA see ETSI TS 136 508 and ETSI TS 136 509 for details regarding generic call set-up procedure and throughput test loop scenarios.
When the EUT is required to be in the idle mode the following conditions shall be met:
- UE shall be camped on a cell;
- UE shall perform Location Registration (LR) before the test, but not during the test;
- UE's neighbour cell list shall be empty;
- paging repetition period and DRX cycle shall be set to minimum (shortest possible time interval).
Adequate measures shall be taken to avoid the effect of immunity RF test signals on the measuring equipment.
2.3.2.3. Arrangements for test signals at the input of transmitters
The provisions of QCVN 18:2014/BTTTT, A.2.1 shall apply. For GSM and DCS, A.2.1 in QCVN 18:2014/BTTTT shall apply with the following modifications:
- The test system shall command the EUT to disable Discontinuous Transmission (DTX);
- A communication link shall be set up between the EUT and the test system.
2.3.2.4. Arrangements for test signals at the output of transmitters
The provisions of QCVN 18:2014/BTTTT, A.2.2 shall apply with the following modifications:
- Where the equipment incorporates an external 50 Ω RF antenna connector that is normally connected via a coaxial cable, then the wanted signal to establish a communication link shall be delivered from that connector by a coaxial cable.
- Where the equipment incorporates an external 50 Ω RF antenna connector, but this port is not normally connected via a coaxial cable, and where the equipment does not incorporate an external 50 Ω RF connector (integral antenna equipment), then the wanted signal, to establish a communication link, shall be delivered from the equipment to an antenna located within the test environment.
2.3.2.5. Arrangements for test signals at the input of receivers
2.3.2.5.1. General

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;
- if the RXQUAL increase or speech output signal level increase still does not disappear with the increased and/or decreased frequency, the phenomena is considered wide band and therefore an EMC problem and the equipment fails the test.
Narrow band responses are disregarded.
2.3.4.2. CDMA Direct Spread (UTRA and E-UTRA) Narrow band responses on receivers
2.3.4.2.1. UTRA
Responses on receivers or duplex transceivers occurring during the immunity tests at discrete frequencies, which are narrow band responses (spurious responses), are identified by the following method:
- if during an immunity test the quantity being monitored goes outside the specified tolerances, it is necessary to establish whether the deviation is due to an 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 I, VIII.
- if the deviation does not disappear, the procedure is repeated with the UARFCN increased or decreased from the original value by:
+ FDD bands I, VIII.
- if the deviation does not disappear with the increased and/or decreased UARFCN, the phenomenon is considered wideband and therefore an EMC problem and the equipment fails the test.
Narrow band responses are disregarded.
2.3.4.2.2. E-UTRA
Responses on receivers or duplex transceivers occurring during the immunity tests at discrete frequencies, which are narrow band responses (spurious responses), are identified by the following method:
- if during an immunity test the quantity being monitored goes outside the specified tolerances, it is necessary to establish whether the deviation is due to an unwanted effect on the receiver of the UE or on the test system (narrow band response) or to a wide band (EMC) phenomenon. Therefore, the test shall be repeated with the unwanted signal frequency increased or decreased by BWChannel MHz, where BWChannel is the channel bandwidth as defined in ETSI TS 136 101;
- if the deviation does not disappear, the procedure is repeated the unwanted signal frequency increased or decreased by 2 × BWChannel MHz,
- if the deviation does not disappear with the increased and/or decreased frequency, the phenomenon is considered wide band and therefore an EMC problem and the equipment fails the test.
Narrow band responses are disregarded.

Annex A
(normative)
CDMA Direct Spread Performance assessment voice call. Audio breakthrough
A.1. Calibration of audio levels
For the portable the audio calibration is performed as follows:
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.
A.2. Measurement of audio levels
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.

CDMA Direct Spread Performance assessment of data transfer call. Error Ratios
B.1.
Calibration of data transfer
B.1.1. UTRA
For the EUT, calibration of the data transfer may be performed by assessing the Bit Error Ratio (BER), Block Error Ratio (BLER) or End-User data error ratio before applying the RF immunity test signal.
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.
The characteristics of the End-User Data used for testing (format, size, typical data throughput rate, additional error corrections, etc.) and the necessary test equipment shall be delivered to enable the assessment of the EUT.
Following formula may apply to End-User Data:
|
Error Ratio |
= |
erroneuos(bits, bytes,symbols,etc.) |
x 100 |
= |
n% |
|
total number of (bits, bytes,symbols,etc.) |
(In case that high Error Ratios exist, ensure that errors are a consequence of EMC stress.)
B.2.2. E-UTRA. Derivation of Throughput Percentages
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 maximum throughput and achieved throughput shall result in the throughput percentage.
The data patterns used should be of sufficient length to give valid results and should be equivalent to the used channel bit rate.
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).

Figure B.1. Error Ratio or throughput assessment, test set-up for EUT without data application ancillary
B.4. EUT with data application ancillary
The Data monitoring Device is here considered as a part of the Test System. The Data application ancillary should be part of the data transfer (UL and DL) loop and is included in the EUT configuration.
