12.1.1.3 Test purpose
1. To verify that conducted spurious emissions from the MS when allocated a channel do not exceed the conformance requirements. These conducted spurious emissions will be measured in the frequency band 100 kHz to 12,75 GHz excluding the following received bands:
For GSM 400, GSM 900 and DCS 1 800:
– the band 925 MHz to 960 MHz;
– the band 1 805 MHz to 1 880 MHz;
– in addition for GSM 400 MS:
– the band 460,4 MHz to 467,6 MHz;
– the band 488,8 MHz to 496 MHz.
For GSM 700, T-GSM 810, GSM 850 and PCS 1 900:
– the band 728 MHz to 746 MHz;
– the band 747 MHz to 763 MHz;
– the band 869 MHz to 894 MHz;
– the band 1 930 MHz to 1 990 MHz.
1.1 Under normal voltage conditions.
1.2 Under extreme voltage conditions.
NOTE: The band 9 kHz to 100 kHz is not tested, because of test implementation problems.
12.1.1.4 Method of test
12.1.1.4.1 Initial conditions
For circuit switched capable devices, a call is set up by the SS according to the generic call set up procedure on a channel in the Mid ARFCN range.
The SS may command the MS to loop back its channel decoder output to channel encoder input.
The SS sends Standard Test Signal C1.
The SS sets the MS to operate at its maximum output power.
For packet switched only devices supporting GMSK only on uplink, a GPRS unacknowledged RLC mode uplink TBF using CS-1 as the uplink coding scheme is established on a channel in the Mid ARFCN range.
For packet switched only devices supporting 8PSK on uplink, an EGPRS unacknowledged RLC mode uplink TBF using MCS-5 as the uplink coding scheme is established on a channel in the Mid ARFCN range.
The MS shall be operated with its highest number of uplink slots.
The Test Mode defined in 3GPP TS 04.14 (subclause 5.4) will be utilised. If the MS is capable of both:
Mode (a) transmitting pseudo-random data sequence in RLC data blocks;
Mode (b) transmitting looped-back RLC data blocks;
then Mode (a) will be used.
If Mode (b) is used then the SS sends the pseudo-random data sequence specified for Mode (a) on the downlink for loopback on the uplink.
The SS sets the power value of each active timeslot to the MS’s maximum power.

12.1.1.4.2 Procedure
a) Measurements are made in the frequency range 100 kHz to 12,75 GHz. Spurious emissions are measured at the connector of the transceiver, as the power level of any discrete signal, higher than the requirement in table 12.1 minus 6 dB, delivered into a 50 load.
The measurement bandwidth based on a 5 pole synchronously tuned filter is according to table 12.2. The power indication is the peak power detected by the measuring system.
The measurement on any frequency shall be performed for at least one TDMA frame period with the exception of the idle frame.
NOTE: This ensures that both the active times (MS transmitting) and the quiet times are measured.
b) The test is repeated under extreme voltage test conditions ([annex 1, TC2.2 and TC3]).

1.1 Under normal voltage conditions.
1.2 Under extreme voltage conditions.
NOTE: The band 9 KHz to 100 kHz is not tested, because of test implementation problems.
12.1.2.4 Method of test
12.1.2.4.1 Initial conditions
The RF power level of the BCCH shall not exceed –80 dBm in order to prevent conflicts in the frequency range 915 MHz to 1000 MHz (see Table 12.6, row 3). The page mode is continuously set to Paging Reorganization and BS_AG_BLKS_RES is set to 0 so that the MS receiver will operate continually.
The CCCH_CONF shall be set to 000. 1 basic physical channel used for CCCH not combined with SDCCHs.
The BCCH allocation shall either be empty or contain only the serving cell BCCH.
NOTE: This is to ensure that the receiver does not scan other ARFCN. Scanning other ARFCN could lead to a moving in frequency of the spurious and therefore to the possibility of either not measuring a spurious emission or measuring it more than once.
For circuit switched capable devices, the MS is in MM state "idle, updated" and the BCCH message content from the serving cell shall ensure that Periodic Location Updating is not used.
For GPRS only devices, the MS is in GMM state “registered, updated”. The value of the Periodic RA Update timer in the GMM ATTACH ACCEPT message shall indicate that the timer is disabled and the BCCH message content shall indicate that SPLIT_PG_CYCLE is not supported on CCCH in the cell and SPLIT_PG_CYCLE has been negotiated at GPRS Attach.
Specific PICS statements:
- MS supporting packet switched services only (TSPC_operation_mode_C).
12.1.2.4.2 Procedure
a) Measurements are made in the frequency range 100 kHz to 12,75 GHz. Spurious emissions are measured as the power level of any discrete signal, higher than the requirement in table 12.4 minus 6 dB, delivered into a 50 load.
The measurement bandwidth based on a 5 pole synchronously tuned filter is set according to table 12.5. The power indication is the peak power detected by the measuring system.
The measurement time on any frequency shall be such that it includes the time during which the MS receives a TDMA frame containing the paging channel.

12.2 Radiated spurious emissions
This test is performed either on an outdoor test site, fulfilling the requirements of [GC4 of annex 1], or in an anechoic shielded chamber, fulfilling the requirements of ([GC5 of annex 1)]. Performing the measurement in the anechoic shielded chamber is preferred. The sample shall be placed at the specified height on the support.
NOTE: The test method described has been written for measurement in an anechoic shielded chamber. If an outdoor test site is used then additional precautions are necessary to ensure correct measurement. These measures are familiar to test houses which perform spurious emissions tests and are:
a) Raise/lower the test antenna through the specified height range during both the emission detection and substitution parts of the test.
b) Perform a qualitative pre-search in a shielded environment for test sites where the ambient RF environment can prevent the detection of spurious emissions which exceed the limit.
c) Detect emissions at a more sensitive threshold to that specified in subclause 12.2.1.4 to allow for destructive interference due to ground plane reflections at the test antenna search height.
12.2.1 MS allocated a channel
12.2.1.1 Definition
Radiated spurious emissions, when the MS has been allocated a channel, are any emissions radiated by the cabinet and structure of the mobile station, including all interconnecting cables.
This is also known as "cabinet radiation".
The test applies to all types of MS with the exception of the test at extreme voltages for an MS where a practical connection, to an external power supply, is not possible.
NOTE: A "practical connection" shall be interpreted to mean it is possible to connect extreme voltages to the MS without interfering with the configuration of the MS in a way which could invalidate the test.
12.2.1.2 Conformance requirement
1. The radiated spurious power emitted by the MS, when allocated a channel, shall be no more than the levels in table 12.7 under normal voltage conditions; 3GPP TS 05.05, subclauses 4.3 and 4.3.3.
2. The radiated spurious power emitted by the MS, when allocated a channel, shall be no more than the levels in table 12.7 under extreme voltage conditions; 3GPP TS 05.05, subclauses 4.3 and 4.3.3, and clause D.2.

12.2.1.3 Test purpose
1. To verify that radiated spurious emissions from the MS when allocated a channel do not exceed the conformance requirements under normal voltage conditions.
2. To verify that radiated spurious emissions from the MS when allocated a channel do not exceed the conformance requirements under extreme voltage conditions.
12.2.1.4 Method of test
12.2.1.4.1 Initial conditions
A call is set up by the SS according to the generic call set up procedure on a channel in the Mid ARFCN range.
NOTE: The power supply shall be connected to the MS such that the physical configuration does not change in a way that could have an effect on the measurement. In particular, the battery pack of the MS should not normally be removed. In cases where no practical connection can be made to the power supply, the MS’s intended battery source shall be used.
The SS may command the MS to loop back its channel decoder output to its channel encoder input.
The SS sends Standard Test Signal C1.
The SS sets the MS to operate at its maximum output power.
12.2.1.4.2 Procedure
a) Initially the test antenna is closely coupled to the MS and any spurious emission radiated by the MS is detected by the test antenna and receiver in the range 30 MHz to 4 GHz.
NOTE 1: This is a qualitative step to identify the frequency and presence of spurious emissions which are to be measured in subsequent steps.
b) The test antenna separation is set to the appropriate measurement distance and at each frequency at which an emission has been detected, the MS shall be rotated to obtain maximum response and the effective radiated power of the emission determined by a substitution measurement. In case of an anechoic shielded chamber pre-calibration may be used instead of a substitution measurement.
c) The measurement bandwidth, based on a 5 pole synchronously tuned filter, is set according to table 12.8. The power indication is the peak power detected by the measuring system.
The measurement on any frequency shall be performed for at least one TDMA frame period, with the exception of the idle frame.
NOTE 2: This ensures that both the active times (MS transmitting) and the quiet times are measured.
NOTE 3: For these filter bandwidths some difficulties may be experienced with noise floor above required measurement limit. This will depend on the gain of the test antenna, and adjustment of the measuring system bandwidth is permissible. Alternatively, for test frequencies above 900 MHz, the test antenna separation from the MS may be reduced to 1 metre.
d) The measurements are repeated with the test antenna in the orthogonal polarization plane.
e) The test is repeated under extreme voltage test conditions (see [annex 1, TC2.2]).

12.3.1.3 Test purpose
1. To verify that conducted spurious emissions, in the frequency band 100 kHz to 12,75 GHz excluding the R-GSM 900, the ER-GSM 900 and DCS 1 800 receive bands, from the MS when allocated a channel do not exceed the conformance requirements.
1.1 Under normal voltage conditions.
1.2 Under extreme voltage conditions.
NOTE: The band 9 kHz to 100 kHz is not tested, because of test implementation problems.
12.3.1.4 Method of test
12.3.1.4.1 Initial conditions
A call is set up by the SS according to the generic call set up procedure on a channel in the Mid ARFCN range.
The SS may command the MS to loop back its channel decoder output to channel encoder input.
The SS sends Standard Test Signal C1.
The SS sets the MS to operate at its maximum output power.
12.3.1.4.2 Procedure
a) Measurements are made in the frequency range 100 kHz to 12,75 GHz. Spurious emissions are measured at the connector of the transceiver, as the power level of any discrete signal, higher than the requirement in table 12.11 minus 6 dB, delivered into a 50 load.
The measurement bandwidth based on a 5 pole synchronously tuned filter is according to table 12.12. The power indication is the peak power detected by the measuring system.
The measurement on any frequency shall be performed for at least one TDMA frame period with the exception of the idle frame.
NOTE: This ensures that both the active times (MS transmitting) and the quiet times are measured.
b) The test is repeated under extreme voltage test conditions ([annex 1, TC2.2 and TC3]).

1.1 Under normal voltage conditions.
1.2 Under extreme voltage conditions.
NOTE: The band 9 kHz to 100 kHz is not tested, because of test implementation problems.
12.3.2.4 Method of test
12.3.2.4.1 Initial conditions
The BCCH message content from the serving cell shall ensure that Periodic Location Updating is not used and that page mode is continuously set to Paging Reorganization and BS_AG_BLKS_RES is set to 0 so that the MS receiver will operate continually.
The CCCH_CONF shall be set to 000. 1 basic physical channel used for CCCH not combined with SDCCHs.
The BCCH allocation shall either be empty or contain only the serving cell BCCH.
NOTE: This is to ensure that the receiver does not scan other ARFCN. Scanning other ARFCN could lead to a moving in frequency of the spurious and therefore to the possibility of either not measuring a spurious emission or measuring it more than once.
The MS is in MM state "idle, updated".
12.3.2.4.2 Procedure
a) Measurements are made in the frequency range 100 kHz to 12,75 GHz. Spurious emissions are measured as the power level of any discrete signal, higher than the requirement in table 12.14 minus 6 dB, delivered into a 50 load.
The measurement bandwidth based on a 5 pole synchronously tuned filter is set according to table 12.15. The power indication is the peak power detected by the measuring system.
The measurement time on any frequency shall be such that it includes the time during which the MS receives a TDMA frame containing the paging channel.

12.4 Radiated spurious emissions for MS supporting the R-GSM or ER-GSM frequency band
This subclause applies only to MS supporting the R-GSM or ER -GSM frequency band.
This test is performed either on an outdoor test site, fulfilling the requirements of [GC4 of annex 1], or in an anechoic shielded chamber, fulfilling the requirements of ([GC5 of annex 1)]. Performing the measurement in the anechoic shielded chamber is preferred. The sample shall be placed at the specified height on the support.
NOTE: The test method described has been written for measurement in an anechoic shielded chamber. If an outdoor test site is used then additional precautions are necessary to ensure correct measurement. These measures are familiar to test houses which perform spurious emissions tests and are:
a) Raise/lower the test antenna through the specified height range during both the emission detection and substitution parts of the test.
b) Perform a qualitative pre-search in a shielded environment for test sites where the ambient RF environment can prevent the detection of spurious emissions which exceed the limit.
c) Detect emissions at a more sensitive threshold to that specified in subclause 12.4.1.4 to allow for destructive interference due to ground plane reflections at the test antenna search height.
12.4.1 MS allocated a channel
12.4.1.1 Definition
Radiated spurious emissions, when the MS has been allocated a channel, are any emissions radiated by the cabinet and structure of the mobile station, including all interconnecting cables.
This is also known as "cabinet radiation".
The test applies to all types of MS with the exception of the test at extreme voltages for an MS where a practical connection, to an external power supply, is not possible.
NOTE: A "practical connection" shall be interpreted to mean it is possible to connect extreme voltages to the MS without interfering with the configuration of the MS in a way which could invalidate the test.
12.4.1.2 Conformance requirement
1. The radiated spurious power emitted by the MS, when allocated a channel, shall be no more than the levels in table 1217 under normal voltage conditions; 3GPP TS 05.05, subclauses 4.3 and 4.3.3.
2. The radiated spurious power emitted by the MS, when allocated a channel, shall be no more than the levels in table 12.17 under extreme voltage conditions; 3GPP TS 05.05, subclauses 4.3 and 4.3.3, and clause D.2.

12.4.1.3 Test purpose
1. To verify that radiated spurious emissions from the MS when allocated a channel do not exceed the conformance requirements under normal voltage conditions.
2. To verify that radiated spurious emissions from the MS when allocated a channel do not exceed the conformance requirements under extreme voltage conditions.
12.4.1.4 Method of test
12.4.1.4.1 Initial conditions
A call is set up by the SS according to the generic call set up procedure on a channel in the Mid ARFCN range.
NOTE: The power supply shall be connected to the MS such that the physical configuration does not change in a way that could have an effect on the measurement. In particular, the battery pack of the MS should not normally be removed. In cases where no practical connection can be made to the power supply, the MS’s intended battery source shall be used.
The SS may command the MS to loop back its channel decoder output to its channel encoder input.
The SS sends Standard Test Signal C1.
The SS sets the MS to operate at its maximum output power.
12.4.1.4.2 Procedure
a) Initially the test antenna is closely coupled to the MS and any spurious emission radiated by the MS is detected by the test antenna and receiver in the range 30 MHz to 4 GHz.
NOTE 0: This is a qualitative step to identify the frequency and presence of spurious emissions which are to be measured in subsequent steps.
b) The test antenna separation is set to the appropriate measurement distance and at each frequency at which an emission has been detected, the MS shall be rotated to obtain maximum response and the effective radiated power of the emission determined by a substitution measurement. In case of an anechoic shielded chamber pre-calibration may be used instead of a substitution measurement.
c) The measurement bandwidth, based on a 5 pole synchronously tuned filter, is set according to table 12.18. The power indication is the peak power detected by the measuring system.
The measurement on any frequency shall be performed for at least one TDMA frame period, with the exception of the idle frame.
NOTE 1: This ensures that both the active times (MS transmitting) and the quiet times are or ER-GSM: 873 MHz to 915 MHz measured.
NOTE 2: For these filter bandwidths some difficulties may be experienced with noise floor above required measurement limit. This will depend on the gain of the test antenna, and adjustment of the measuring system bandwidth is permissible. Alternatively, for test frequencies above 900 MHz, the test antenna separation from the MS may be reduced to 1 metre.
d) The measurements are repeated with the test antenna in the orthogonal polarization plane.
e) The test is repeated under extreme voltage test conditions (see [annex 1, TC2.2]).

12.4.2.4 Method of test
12.4.2.4.1 Initial conditions
NOTE 1: The power supply shall be connected to the MS such that the physical configuration does not change in a way that could have an effect on the measurement. In particular, the battery pack of the MS should not normally be removed. In cases where no practical connection can be made to the power supply, the MS’s intended battery source shall be used.

The BCCH allocation shall either be empty or contain only the serving cell BCCH.
NOTE 2: This is to ensure that the receiver does not scan other ARFCN. Scanning other ARFCN could lead to a moving in frequency of the spurious and therefore to the possibility of either not measuring a spurious emission or measuring it more than once.
The MS is in MM state "idle, updated".
12.4.2.4.2 Procedure
a) Initially the test antenna is closely coupled to the MS and any spurious emission radiated by the MS is detected by the test antenna and receiver in the range 30 MHz to 4 GHz.
NOTE 1: This is a qualitative step to identify the frequency and presence of spurious emissions which are to be measured in subsequent steps.
b) The test antenna separation is set to the appropriate measurement distance and at each frequency at which a spurious emission has been detected the MS is rotated to obtain a maximum response. The effective radiated power of the emission is determined by a substitution measurement. In case of an anechoic shielded chamber pre-calibration may be used instead of a substitution measurement.
c) The measurement bandwidth based on a 5 pole synchronously tuned filter shall be according to table 12.20. The power indication is the peak power detected by the measuring system.
The measurement time on any frequency shall be such that it includes the time during which the MS receives a TDMA frame containing the paging channel.
NOTE 2: For these filter bandwidths some difficulties may be experienced with noise floor above required measurement limit. This will depend on the gain of the test antenna, and adjustment of the measuring system bandwidth is permissible.
