1 Scope

The present document covers the technical requirements for multiple channel radio transmitters used in stations in the

Private Mobile Radio (PMR) service.

It applies to use in the land mobile service, operating on radio frequencies between 30 MHz and 3 GHz, with channel

separations of < 10 kHz, 12,5 kHz, 20 kHz, 25 kHz, 50 kHz, 100 kHz and 150 kHz.

Table 1: Radiocommunications service frequency bands

Radiocommunications service frequency bands

Transmit 30 MHz to 3 000 MHz

It applies to equipment for continuous and/or discontinuous transmission of data and/or digital speech and/or analogue

speech and using constant envelope or non-constant envelope modulation.

The equipment comprises a transmitter capable of simultaneous amplification or transmission on two or more RF

channels, or an amplifier which when operated with transmitter equipment provides simultaneous transmission on two

or more RF channels. The types of equipment covered by the present document are as follows:

base station (equipment fitted with an antenna connector, intended for use in a fixed location);

mobile station (equipment fitted with an antenna connector, normally used in a vehicle or as a transportable);

those hand portable stations:

a) fitted with an antenna connector; or

b) without an external antenna connector (integral antenna equipment), but fitted with a permanent internal

or a temporary internal 50 Ω Radio Frequency (RF) connector which allows access to the transmitter

output; and

and any equipment that may be used in combination with any of the above equipments when directly connected to those equipments for the amplification of the transmitter output signals of two or more individual

equipments.

Types of equipment not covered by the present document are as follows:

hand portable equipment without an external or internal RF connector and without the possibility of having a temporary internal 50 Ω RF connector is not covered by the present document;

any equipment using passive combining solutions where each transmitter connected to the passive combining system transmits on a single channel, as detailed in ETSI EG 200 053 [i.2], clause H.3.

These specifications apply to the transmitter or transmitter amplifier only. If a receiver is fitted to the same equipment,

the receiver specifications in the relevant specification (references [i.5] to [i.12]) shouldalso apply.

These specifications do not necessarily include all the characteristics that may be required by a user of equipment, nor

do they necessarily represent the optimum performance achievable.

The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [i.3] (R&TTE

Directive), which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated

to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".

In addition to the present document, other ENs that specify technical requirements in respect of essential requirements

under other parts of article 3 of the R&TTERadio Equipment Directive [i.3i.3] may apply to equipment within the scope

of the present document.

NOTE: A list of such ENs is included on the web site http://www.newapproach.org.

5.5.1 Procedure for equipment designed for continuous transmission

If the manufacturer states that the equipment is designed for continuous transmission, the test procedure shall be as follows.

Before tests at the upper extreme temperature, the equipment shall be placed in the test chamber, and left until thermal

balance is attained. The equipment shall then be switched on in the transmit condition with modulation M1, M2, A1 or B1

(as appropriate, see clause 6.3.1), for a period of half an hour, after which the equipment shall meet the specified

requirements.

Before tests at the lower extreme temperature, the equipment shall be left in the test chamber until thermal balance is

If the manufacturer states that the equipment is designed for intermittent transmission, the test procedure shall be as

follows:.

Before tests at the upper extreme temperature, the equipment shall be placed in the test chamber, and left until thermal

balance is attained. The equipment shall then be switched on for one minute in the transmit condition with modulation

equipment shall meet the specified requirements.

For tests at the lower extreme temperature, the equipment shall be left in the test chamber until thermal balance is

lowest and highest edges of the necessary bandwidth.

The equipment shall be configured with the maximum number of channels, and with the maximum possible bandwidth

for test conditions.

6.2 Test load (artificial antenna)

For conducted measurements of the transmitter, a power attenuator ("artificial antenna") shall be used, exhibiting a

substantially non-reactive, non-radiating load of 50 to the antenna connector and capable of dissipating the

transmitter output power.

6.3 Test signals (wanted and unwanted signals)

6.3.0 General

The manufacturer shall declare details of the modulation scheme(s) used on each of the simultaneously transmitted

channels, and the maximum number of channels that can be simultaneously transmitted by the equipment.

If a frequency conversion oscillator is used which produces an in-band spurious emission, the manufacturer shall

declare the frequency and the tunable range of this oscillator.

6.3.1 Transmitter test signals for digital transmissions

The manufacturer shall declare details of the modulation scheme(s) used on each of the simultaneously transmitted

channels. This shall be considered the normal modulation of the equipment.

Test signal M1 shall consist of a pseudo-random bit sequence of at least 511 bits (according to Recommendation

ITU-T O.153 [1]), at the appropriate data rate.

If the transmission of a continuous bit stream is not possible, test signal M2 shall be trains of correctly coded bits or

messages. An encoder of the type defined in clause 6.3.2 may be used.

For the purpose of testing PX in clause 7.1 test signals M1 and M2 should produce the largest value of output power

(PEP) possible. If this is not the case then a test signal that does produce the largest possible value of output power

(PEP) shall be used in the testing in clause 7.1.

For equipment that supports adaptive rates, testing is only required at one bit rate. For transmitter tests in clause 7 this

would normally be the highest bit-rate supported by the equipment.

Manufacturers shall declare where any of the specific tests in clause 7, if conducted at rates other than the highest bit

rate, are likely to give results which are worse than at the highest bit rate. In such cases the tests shall be carried out at

the rate declared by the manufacturer that is likely to give the worst performance (least margin between measured

results and test limits).

6.3.2 Encoder for digital transmitter measurements

It is permissible to use an encoder to provide coded data from a pseudo-random bit sequence of at least 511 bits

(according to Recommendation ITU-T O.153 [1]). Whenever a transmitter is not rated for continuous operation, the

coded data may be transmitted in a discontinuous manner following as closely as possible the normal transmission

characteristics of the EUT.

500 Hz separation between them, each of which would independently drive the transmitter into its compression region.

The composite signal level shall be 20 dB higher than the level which produces 60 % modulation unless the output

power at this drive level is less than the highest Tx output power in which case the signal level shall be set to produce

the highest possible Tx output power.

Equipment that does not integrate the keyboard and display used for normal operation shall provide a suitable interface.

In the case where the equipment uses a proprietary interface, appropriate means and documentation allowing for the

equipment to be tested are expected to be provided in view of the measurements.

Variation in the level of the input signals, within the specified limits for that interface, shall have no measurable

influence on the characteristics of the signals on the radio path.

6.5 Impedance

In the present document the term "50 Ω" is used for a 50 Ω non-reactive impedance.

6.6 PEP

The PEP of a transmitter is the average power supplied to the artificial antenna by the transmitter during one RF cycle at

the highest crest of the modulation envelope.

6.7 Duplex equipment

If the equipment is provided with a built-in duplex filter or with a separate associated filter, the requirements of the

present document shall be met when the measurements are carried out using the antenna connector of the filter.

Duplex equipment having integral antenna may be tested using the internal or temporary antenna connector.

6.8 Modes of operation of the transmitter

Measurements shall be made with the transmitter being modulated representative of normal operation. If the transmitter

is capable of being operated in more than one mode (e.g. continuous and burst modes) then it shall be tested in all such

modes. The maximum and minimum bust durations shall be declared (and shall be declared for all channels if different

durations are used on different channels).

ETSI

ETSI EN 303 039 V2.1.2 (2016-10) 20

If the equipment is fitted with an automatic transmitter shut-off facility it shall be made inoperative for the duration of

the type test, unless it has to be left operative to protect the equipment.

The characteristics (continuous or discontinuous transmission, burst duration) of the transmission modes used for each

of the following measurements shall be stated in the test report.

applied to input ports for all channels of the transmitter. The modulation used shall be recorded in the test report.

All channels within the transmitter bandwidth shall be set to maximum power, and shall be set such that there is less

7.2 Adjacent and alternate channel power

7.2.1 Definition

The adjacent channel power is that part of the total output power of a wanted channel under defined conditions of

modulation, which falls within specified passbands centred on the nominal frequency of either of the channels adjacent

to that wanted channel.

The alternate channel power is that part of the total output power of a transmitter, under defined conditions of

modulation, which falls within specified passbands centred on the nominal frequency of any of the alternate channels,

and measured with respect to the channel with the highest power output of the transmitter.

These powers are the sum of the rms powers produced by the modulation, hum and noise of the transmitter.

For equipment having a nominal channel bandwidth of 25 kHz and greater, the adjacent and 1st and 2nd alternate channels

are defined as having channel bandwidths of 25 kHz, the specified passband of which is equal to the bandwidth of a square

root raised cosine filter given in clause 6.9. The centre frequencies of the adjacent channels are frequencies of

(fc ± (12,5 + BW/2)) kHz, where fc is the centre frequency of the wanted channel and BW is the channel bandwidth of

the wanted channel. The centre frequencies of the alternate channels are frequencies of (fc ± (37,5 + BW/2) kHz

(1st alternate channels) and (fc ± (62,5 + BW/2) kHz (2nd alternate channels).)).

For equipment using a nominal channel bandwidth of less than 25 kHz, the adjacent and alternate channels are defined

as having measurement bandwidths of:

For 20 kHz wanted channel bandwidth: measurement bandwidth equal to 14 kHz.

For 12,5 kHz wanted channel bandwidth: measurement bandwidth equal to 8,5 kHz.

ETSI EN 303 039 V2.1.2 (2016-10) 23

A channel may be adjacent or alternate to more than one channel, or may be adjacent to one or more channels and

alternate to one or more channels.

7.2.2 Method of measurement

The adjacent and alternate channel powers shall be measured with a spectrum analyser for channel bandwidths of

greater than 25 kHz, or a spectrum analyser or power measuring receiver with an appropriate channel bandwidth for

bandwidths of 25 kHz or less. An equivalent measurement instrument, which conforms with the requirements given in

annex C may be used instead.

The transmitter shall be operated at the value of PX determined under normal test conditions. All channels within the

transmitter bandwidth shall be set to maximum power, and shall be set such that there is less than 1 dB variation in

levels between channels. If this is not possible, then each channel shall be set to its maximum individual power.

The transmitter shall be operated with its maximum number of channels, and with the maximum specified frequency

spacing between highest and lowest frequency channels.

The wanted channels of the transmitter shall be modulated with test signal M1 M2, A2 or B1 as appropriate. The

modulation used shall be recorded in the test report.

The transmitter shall be tested at the maximum and minimum burst mode durations as declared with all channels

operating at their maximum power level (where maximum burst duration may be continuous operation). The

measurements shall be carried out in a period shorter than the duration of the transmitted burst but not less than 90 % of

the useful part of the burst.

The output of the transmitter shall be connected to the input of the spectrum analyser or power measuring receiver by a

50 power attenuator, to ensure that the impedance presented to the transmitter is 50 and the level at the test

equipment input is appropriate.

The resolution bandwidth of the spectrum analyser, if used, shall be: 1 000 Hz for channels bandwidths 25 kHz;

500 Hz for channel bandwidths between greater than 10 kHz but less than 25 kHz and 300 Hz for channel bandwidths

≤ 10 kHz.

Initially the longest burst duration permitted by the EUT shall be used or a steady state measurement after 15 minutes of

operation if continuous operation is permitted.

The rms power present in each of the wanted channels, measured on the spectrum analyser or power measuring

receiver, shall be recorded as the reference wanted channel power, PR for each wanted channel. If a power measuring

receiver is used, the attenuator setting and meter reading shall be noted for each channel to determine PR. For the

purposes of the measurement limit, the highest rms power PRX of all the individual PR measurements of the channels

of the transmitter shall be determined.

For the purpose of the remainder of this test the measurement bandwidth (MBW) shall be equal to the specified

passband of the adjacent and alternate channels (clause 7.2.1) relevant to the wanted channel to which the measured

channel is adjacent, or if a spectrum analyser is used for wanted channel bandwidths of 25 kHz or greater, a power

measuringmeasurement bandwidth of 18 kHz shall be used.

For each wanted channel., the MBW shall be centred on the centre frequency of the upper adjacent channel. The rms

power present in the MBW shall be recorded (the adjacent channel power). If a power measuring receiver is used, the

attenuator setting and meter reading shall be noted.

The measurement shall be repeated with the MBW centred on the centre frequency of the lower adjacent channel.

The measurement shall be repeated for each of the channels of the transmitter in turn.

If an adjacent channel of one wanted channel is contained within or overlapped by the wanted bandwidth of another

channel, the measurement shall not be made for that adjacent channel.

A channel may be adjacent to one or two wanted channels, and may also be alternate to one or more wanted channels.

The highest value of all adjacent channel power measurements shall be taken as the adjacent channel power for the

transmitter, irrespective of whether the measured channel is adjacent or alternate to more than one wanted channel.

The measurement shall be made under normal test conditions (see clause 5.3) and repeated under extreme test

conditions (clauses 5.4.1 and 5.4.2 applied simultaneously).

ETSI

ETSI EN 303 039 V2.1.2 (2016-10) 24

Where all channels have been set with less than 1 dB power variation, the adjacent channel power ratio is the difference

(in dB) between the highest rms measured wanted power of all channels (PRX) under normal test conditions and the

largest measured adjacent channel power.

Where test are conducted under normal and extreme test conditions, this results in two values for the adjacent channel

power ratio.

If the channels of the transmitter cannot be set such that the variation between channels is less than 1 dB, an adjacent

channel power measurement shall be made for each channel of the transmitter in turn and the ratio for each channel

calculated as the difference (in dB) between the measured wanted power of that channel and the higher of the two

adjacent channel powers for that channel. If a channel is adjacent to two wanted channels, the adjacent channel power

ratio shall be the ratio between the power of the higher of the wanted channel powers and the power measured in the

adjacent channel. The lowest ratio of wanted power to adjacent channel power of all of the channels shall be recorded as

the adjacent channel power ratio of the transmitter.

Alternatively, if the spectrum analyser measures rms adjacent channel power automatically, the adjacent channel power

(in dB) may be measured directly at normal and extreme test conditions. The analyser should use an analogue

measurement method without frequency weighting and not using an accelerated method. The adjacent channel power

ratio is the smaller of the calculated ratios from the two channels above and below each wanted channel, excluding any

adjacent channel which is contained within or overlapped by the wanted bandwidth of another carrier.

The measurement shall be repeated with the MBW centred on the centre frequencies of each of the 1st and 2nd upper

and lower alternate channels for each wanted channel in the transmitter in turn. The rms power present in the MBW

shall be recorded (the alternate channel power) for each of these channels. The measurement shall be made under

normal test conditions (see clause 5.3) and repeated under extreme test conditions (see clauses 5.4.1 and 5.4.2 applied

simultaneously). Automatic measurement may also be used if supported by the spectrum analyser. If an alternate

channel is also adjacent to another wanted channel, the measurement shall not be made for that channel as it will

already have been measured as an adjacent channel. If an alternate channel is also alternate to one or more other wanted

channels, the number of channels to which the measured channel is alternate shall be recorded.

Where all channels have been set with less than 1 dB power variation, the alternate channel power ratio is the difference

(in dB) between the highest rms measured integrated wanted channel power of all channels under normal test conditions

(PRX) and the measured alternate channel power.

For measured channels that are alternate to only one wanted channel, the ratio obtained with the largest power reading

from all alternate channels shall be recorded. For measured channels that are alternate to two wanted channels, the ratio

obtained with the largest power reading for all measured channels that are alternate to two channels shall be recorded.

For measured channels that are alternate to three or more channels, the ratio obtained with the largest power reading for

all measured channels alternate the three or more channels shall be recorded. Thus up to three alternate power ratios

may be recorded for the transmitter under test.

Where tests are conducted under normal and extreme test conditions, this results in two sets of values for the alternate

channel power ratio.

If the channels of the transmitter cannot be set such that the variation between channels is less than 1 dB, a

measurement shall be made independently of alternate power ratios for each channel of the transmitter in turn, except

where an alternate channel is also a wanted channel or is adjacent to a wanted channel in which case no measurement

shall be made. If a channel is alternate to two or more wanted channels, the alternate channel power ratio shall be the

ratio between the power of the higher of the wanted channel powers and the power measured in the alternate channel.

Alternate channel power ratios shall be recorded for channels that are alternate to one channel, alternate to two

channels, and alternate to three or more channels, and in each case the lowest power ratio from all measurements of

each combination (i.e. alternate to one, two or three or more channels) across all channels of the transmitter shall be

recorded. Thus up to three alternate power ratios may be recorded for the transmitter under test.

The tests shall be repeated with the transmitter operated with its maximum number of channels, and with the minimum

specified frequency spacing between highest and lowest frequency channels. Where the minimum spacing allows all the

carriers to be adjacent then the test shall also be repeated with a spacing of one channel between each of the transmitter

channels.

The tests shall be repeated using the shortest burst duration supported by the EUT.

7.3 Unwanted emissions

7.3.1 Definition

Unwanted emissions are emissions on a frequency, or frequencies, which are outside the necessary bandwidth of the

wanted channels of the transmitter equipment and the level of which may be reduced without affecting the

corresponding transmission of information. Unwanted emissions include harmonic emissions, parasitic emissions,

intermodulation products and frequency conversion products but exclude adjacent and alternate channel emissions. For

the purpose of the present document there are three bands defined:

The in-band domain is the necessary bandwidth of the transmitter, which includes the wanted bandwidths of the highest and lowest frequency channels transmitted. Unwanted emissions in the in-band domain shall not be

measured on any frequency defined as an adjacent or alternate channel frequency to any channel transmitted

by the equipment.

The out-of-band (OOB) domain consists of frequencies within ±250 % of the transmitter necessary bandwidth, excluding the transmitter necessary bandwidth, and is measured from the centre frequency of the transmitter.

The centre frequency of the transmitter is the mid frequency between the highest and lowest channel

frequencies. The centre frequencies of the out-of-band domain are therefore those frequencies at ±150 % of the

transmitter necessary bandwidth measured from the centre frequency of the transmitter. Unwanted emissions

in the out-of-band domain shall not be measured on any frequency defined as an adjacent or alternate channel

frequency to any channel transmitted by the equipment.

The spurious domain is taken as all other frequencies which are not included in the in-band or the out-of-band domains.

The domains are illustrated in figure 4.

Figure 4: Unwanted Emissions Boundaries

Table 4

For BN ≤ 10 MHz For BN > 10 MHz

The lower boundary for OOB limits is: Blow2 = (flow / 2) + (fhigh / 2) - (2,5 BN)

Bhigh2 = (flow / 2) + (fhigh / 2) + (2,5 BN)

The lower boundary for OOB limits is: Blow2 = (flow / 2) + (fhigh / 2) - (1,5 BN + 10)

Bhigh2 = (flow / 2) + (fhigh / 2) + (1,5 BN + 10)

The centre frequency of the OOB domain is: Blow1 = (flow / 2) + (fhigh / 2) - (1,5 BN)

Bhigh1 = (flow / 2) + (fhigh / 2) + (1,5 BN)

The centre frequency of the OOB domain is: Blow1 = (flow / 2) + (fhigh / 2) - (0,5 BN + 10)

Bhigh1 = (flow / 2) + (fhigh / 2) + (0,5 BN + 10)

Where:

All frequencies are in MHz.

Blow1, Blow2, Bhigh1, Bhigh2, fhigh, flow are shown in figure 34.

BN is the necessary bandwidth.

Third order intermodulation products can arise between wanted channels of the transmitter. Limits are specified in

clause 7.3.3.4 for these products where they arise between Blow1 to Bhigh1; outside this frequency range the limits in

clause 7.3.3.1 shall apply. In order that it can be classified as a third order intermodulation product, the frequency of the

spurious emission Ii caused by intermodulation between two wanted channels of frequencies Fa and Fb shall satisfy one

of the equations:

Ii = 2Fa - Fb or Ii = 2Fb - Fa

Alternatively the frequency of spurious emission Ii between three wanted channels of frequencies Fa, Fb and Fc shall

satisfy one of the equations:

Ii = Fa + Fb - Fc or Ii = Fa + Fc - Fb or Ii = Fb + Fc - Fa

7.3.2 Method of measuring the power level

7.3.2.1 Measurement options

The level of spurious emissions shall be considered to be either:

a) their power level in a specified load (conducted spurious emission); and

b) their effective radiated power when radiated by the cabinet and structure of the equipment (cabinet radiation); or

c) their effective radiated power when radiated by the cabinet and by the integral antenna, in the case of hand portable equipment fitted with such an antenna and no external RF connector.

NOTE: There are only two options allowed: either both a) and b) or only c).

Specific measurements are made on frequencies where spurious emissions result from a frequency conversion oscillator

(clause 7.3.2.5) and where third order intermodulation products exist between wanted channels (clause 7.3.2.6).

In addition equipment shall be specifically measured for wideband noise.

7.3.2.2 Method of measuring conducted spurious emissions (clause 7.3.2.1 a))

Spurious emissions shall be measured as the mean power level of any signal delivered into a 50 load. This may be

done by connecting the transmitter output through an attenuator to either a spectrum analyser (see also annex C) or

selective voltmeter or by monitoring the relative levels of the spurious signals delivered to an artificial antenna (see

clause 6.2).

The transmitter shall be operated at power PX. All channels of th
