ETSI ETSI EN 301 783-1 V1.2.1 (2010-07) 7 3 Definitions, symbols and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: Single SideBand (SSB): any emission using Single SideBand (SSB) suppressed carrier format 3.2 Symbols For the purposes of the present document, the following symbols apply: Bn Necessary bandwidth of an emission PX Maximum PEP 3.3 Abbreviations For the purposes of the present document, the following abbreviations apply: AM Amplitude Modulation CBW Channel BandWidth CSP Channel SPacing DC Direct Current EUT Equipment Under Test FM Frequency Modulation HF High Frequency OATS Open Area Test Site PEP Peak Envelope Power RBW Resolution BandWidth SSB Single SideBand RF Radio Frequency SINAD (Signal + Noise + Distortion) / (Noise + Distortion) Tx Transmit UHF Ultra High Frequency VHF Very High Frequency VSWR Voltage Standing Wave Ratio 4 Technical requirements specifications 4.1 Environmental profile The environmental profile for operation of the equipment shall be declared by the supplier. The equipment shall comply with all the technical requirements of the present document at all times when operating within the boundary limits of the required operational environmental profile. 4.2 EUT test frequencies Testing shall be performed with the EUT set to frequencies as follows: • single-band equipment: test at the centre of the band; • double-band equipment: test at the centre of both bands; • HF multi-band equipment or VHF/UHF multi-band equipment: test at the centre of the lowest, the centre of the middle, and the centre of the highest band; SIST EN 301 783-1 V1.2.1:2010
ETSI ETSI EN 301 783-1 V1.2.1 (2010-07) 8 • HF/VHF, HF/UHF or HF/VHF/UHF combined equipment: test at the centre of the lowest HF band, the centre of the middle HF band, the centre of the highest HF band, the centre of the lowest VHF/UHF band, the centre of the middle VHF/UHF band, and the centre of the highest VHF/UHF band. 4.3 Test power source During testing the power source of the equipment shall be replaced by a test power source capable of producing the nominal supply voltage for the equipment as declared by the manufacturer. The internal impedance of the test power source shall be low enough for its effect on the test results to be negligible. For the purpose of tests, the voltage of the power source shall be measured at the input terminals of the equipment. For battery operated equipment the battery shall be removed and the test power source shall be applied as close to the battery terminals as practicable. During tests of DC powered equipment the power source voltages shall be maintained within a tolerance of < ±1 % relative to the voltage at the beginning of each test. The value of this tolerance is critical for power measurements, using a smaller tolerance will provide better measurement uncertainty values. 4.3.1 Mains voltage The normal test voltage for equipment to be connected to the mains shall be the nominal mains voltage. For the purpose of the present document, the nominal voltage shall be the declared voltage or any of the declared voltages for which the equipment was designed. The frequency of the test power source corresponding to the ac mains shall be between 49 Hz and 51 Hz. 4.3.2 Regulated lead-acid battery power sources used on vehicles When the radio equipment is intended for operation from the usual types of regulated lead-acid battery power source used on vehicles the normal test voltage shall be 1,1 times the nominal voltage of the battery (for nominal voltages of 6 V and 12 V, these are 6,6 V and 13,2 V respectively). 4.3.3 Other power sources For operation from other power sources or types of battery (primary or secondary), the normal test voltage shall be that declared by the equipment manufacturer. 4.4 Testing of equipment that does not have an external 50 Ω RF connector (integral antenna equipment) Where equipment has an internal 50 Ω connector it shall be permitted to perform the tests at this connector. Equipment may also have a temporary internal 50 Ω connector installed for the purposes of testing. No connection shall be made to any internal permanent or temporary antenna connector during the performance of radiated emissions measurements, unless such action forms an essential part of the normal intended operation of the equipment, as declared by the manufacturer. 4.5 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 Ω to the antenna connector and capable of dissipating the transmitter output power. SIST EN 301 783-1 V1.2.1:2010
ETSI ETSI EN 301 783-1 V1.2.1 (2010-07) 9 4.6 PEP The PEP is the average power in watts supplied to the artificial antenna by a transmitter during one RF cycle at the highest crest of the modulation envelope. For practical purposes the methods of measurements in clause 5.1 should be used. 4.7 Transmitter automatic shut-off facility 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. 4.8 Arrangement for analogue test signals at the input of the transmitter For the purpose of the present document, in the case of analogue equipment, the transmitter audio frequency modulation signal shall be applied to the terminals of the audio input connector with any microphone disconnected, unless otherwise stated. 4.9 Arrangement for test signals at the input of the receiver RF test signal sources which are applied to the receiver shall present an impedance of 50 Ω to the receiver input. This requirement shall be met irrespective of whether one or more signals using a combining network are applied to the receiver simultaneously. The levels of the test signals shall be expressed in terms of the emf at the receiver input connector. The effects of any intermodulation products and noise produced in the test signal sources shall be negligible. 4.10 Characteristics of test signals at the input of the receiver Wanted RF test signals applied to the receiver shall have the modulation characteristics as specified in table 1. Table 1: Wanted test signal Mode Units Modulation AM 60 % AM (1 kHz) FM 60 % of the maximum permissible frequency deviation (1 kHz) SSB 1 kHz offset None Other modes as declared by the manufacturer as declared by the manufacturer
4.11 Characteristics of test signals at the input of the transmitter The manufacturer shall declare details of the modulation scheme used and identify how the percentage modulation can be measured or specified. Equipment capable of transmission of digital information shall be tested with modulation as specified in clause 4.11.2. Equipment using analogue transmission shall be tested with modulation as specified in clause 4.11.1. Equipment capable of both analogue and digital transmission shall be tested separately in each mode. SIST EN 301 783-1 V1.2.1:2010
ETSI ETSI EN 301 783-1 V1.2.1 (2010-07) 10 4.11.1 Analogue signals For tests on analogue equipment via the audio input socket terminals, the test signal shall consist of two equal amplitude non harmonically related sinusoidal input signals selected to be in the range 500 Hz to 3 kHz with at least 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. For tests via any facilities sockets this test signal shall be of the nature described by the manufacturer for the purpose of the socket , at a level which produces the largest value of output power (PEP) possible with analogue modulation. 4.11.2 Digital signals For tests on digital equipment (including digital speech), the test signal be as declared by the manufacturer, at the appropriate data rate. If the transmission of a continuous bit stream is not possible, the test signal shall be trains of correctly coded bits or messages. For the purpose of testing PX in clause 5.1 the test signal shall produce the largest value of output power (PEP) possible with digital modulation. If this is not the case then a test signal that does produce the largest possible value of output power (PEP) with digital modulation should be used in the testing in clause 5.1. For digital equipments that support adaptive rates, testing is only required at one bit rate. For transmitter tests in this clause this would normally be the highest bit-rate supported by the equipment. 4.12 Reference bandwidths for spurious measurements The reference bandwidths applicable for all spurious measurement are given in table 2. Table 2: Reference bandwidths to be used for the measurement of spurious emissions Frequency range RBW 9 to 150 kHz 1 kHz 150 kHz to 30 MHz 10 kHz 30 MHz to 1 GHz 100 kHz Above 1 GHz 1 MHz
4.13 Transmit exclusion bandwidths for spurious measurements When measuring transmit spurious emissions, an exclusion band centred on the wanted carrier is defined as 250 % of the CSP. The minimum values of necessary bandwidth (Bn) applicable depend on the operating frequency of the equipment as defined in CEPT/ERC/Recommendation 74-01 [i.2]. The combination of 250 % of the CSP and these necessary bandwidths result in the following transmit exclusion bands for spurious measurements in table 3. Table 3: Transmit exclusion bands for the measurement of spurious emissions Operating freq Bn minimum Tx exclusion band Below 30 MHz 4 kHz 10 kHz 30 MHz to 1 GHz 25 kHz 62,5 kHz 1 GHz to 26 GHz 100 kHz 250 kHz Above 26 GHz 1 MHz 2,5 MHz
Where the necessary bandwidth of the emission being measured is greater than the minimum values given in table 3, the transmit excl

ETSI
---------------------- Page: 7 ----------------------
8 Draft ETSI EN 301 783-1 V1.2.1 (2009-07)
• HF multi-band equipment or VHF/UHF multi-band equipment: test at the centre of the lowest, the centre of
the middle, and the centre of the highest band;
• HF/VHF, HF/UHF or HF/VHF/UHF combined equipment: test at the centre of the lowest HF band, the centre
of the middle HF band, the centre of the highest HF band, the centre of the lowest VHF/UHF band, the centre
of the middle VHF/UHF band, and the centre of the highest VHF/UHF band.
4.3 Test power source
During testing the power source of the equipment shall be replaced by a test power source capable of producing the
nominal supply voltage for the equipment as declared by the manufacturer. The internal impedance of the test power
source shall be low enough for its effect on the test results to be negligible. For the purpose of tests, the voltage of the
power source shall be measured at the input terminals of the equipment.
For battery operated equipment the battery shall be removed and the test power source shall be applied as close to the
battery terminals as practicable.
During tests of DC powered equipment the power source voltages shall be maintained within a tolerance of < ±1 %
relative to the voltage at the beginning of each test. The value of this tolerance is critical for power measurements, using
a smaller tolerance will provide better measurement uncertainty values.
4.3.1 Mains voltage
The normal test voltage for equipment to be connected to the mains shall be the nominal mains voltage. For the purpose
of the present document, the nominal voltage shall be the declared voltage or any of the declared voltages for which the
equipment was designed.
The frequency of the test power source corresponding to the ac mains shall be between 49 Hz and 51 Hz.
4.3.2 Regulated lead-acid battery power sources used on vehicles
When the radio equipment is intended for operation from the usual types of regulated lead-acid battery power source
used on vehicles the normal test voltage shall be 1,1 times the nominal voltage of the battery (for nominal voltages of
6 V and 12 V, these are 6,6 V and 13,2 V respectively).
4.3.3 Other power sources
For operation from other power sources or types of battery (primary or secondary), the normal test voltage shall be that
declared by the equipment manufacturer.
4.4 Testing of equipment that does not have an external 50 Ω
RF connector (integral antenna equipment)
Where equipment has an internal 50 Ω connector it shall be permitted to perform the tests at this connector.
Equipment may also have a temporary internal 50 Ω connector installed for the purposes of testing.
No connection shall be made to any internal permanent or temporary antenna connector during the performance of
radiated emissions measurements, unless such action forms an essential part of the normal intended operation of the
equipment, as declared by the manufacturer.
4.5 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 Ω to the antenna connector and capable of dissipating the
transmitter output power.

4.6 PEP
The PEP is the average power supplied to the artificial antenna by a transmitter during one RF cycle at the highest crest
of the modulation envelope. For practical purposes the methods of measurements in clause 5.1 should be used.
4.7 Transmitter automatic shut-off facility
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.
4.8 Arrangement for analogue test signals at the input of the
transmitter
For the purpose of the present document, in the case of analogue equipment, the transmitter audio frequency modulation
signal shall be applied to the terminals of the audio input connector with any microphone disconnected, unless
otherwise stated.
4.9 Arrangement for test signals at the input of the receiver
RF test signal sources which are applied to the receiver shall present an impedance of 50 Ω to the receiver input. This
requirement shall be met irrespective of whether one or more signals using a combining network are applied to the
receiver simultaneously.
The levels of the test signals shall be expressed in terms of the emf at the receiver input connector.
The effects of any intermodulation products and noise produced in the test signal sources shall be negligible.
4.10 Characteristics of test signals at the input of the receiver
Wanted RF test signals applied to the receiver shall have the modulation characteristics as specified in table 1.
Table 1: Wanted test signal
Mode Units Modulation
AM 60 % AM (1 kHz)
FM 60 % of the maximum
permissible frequency
deviation (1 kHz)
SSB 1 kHz offset None
Other modes as declared by the as declared by the manufacturer
manufacturer
4.11 Characteristics of test signals at the input of the transmitter
The manufacturer shall declare details of the modulation scheme used and identify how the percentage modulation can
be measured or specified.
Equipment capable of transmission of digital information shall be tested with modulation as specified in clause 4.11.2.
Equipment using analogue transmission shall be tested with modulation as specified in clause 4.11.1. Equipment
capable of both analogue and digital transmission shall be tested separately in each mode.

4.11.1 Analogue signals
For tests on analogue equipment via the audio input socket terminals, the test signal shall consist of two equal amplitude
non harmonically related sinusoidal input signals selected to be in the range 500 Hz to 3 kHz with at least 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.
For tests via any facilities sockets this test signal shall be of the nature described by the manufacturer for the purpose of
the socket , at a level which produces the largest value of output power (PEP) possible with analogue modulation.
4.11.2 Digital signals
For tests on digital equipment (including digital speech), the test signal be as declared by the manufacturer, at the
appropriate data rate.
If the transmission of a continuous bit stream is not possible, the test signal shall be trains of correctly coded bits or
messages.
For the purpose of testing PX in clause 5.1 the test signal shall produce the largest value of output power (PEP) possible
with digital modulation. If this is not the case then a test signal that does produce the largest possible value of output
power (PEP) with digital modulation should be used in the testing in clause 5.1.
For digital equipments that support adaptive rates, testing is only required at one bit rate. For transmitter tests in this
clause this would normally be the highest bit-rate supported by the equipment.
4.12 Reference bandwidths for spurious measurements
The reference bandwidths applicable for all spurious measurement are given in table 2.
Table 2: Reference bandwidths to be used for the measurement of spurious emissions
Frequency range RBW
9 to 150 kHz 1 kHz
150 kHz to 30 MHz 10 kHz
30 MHz to 1 GHz 100 kHz
Above 1 GHz 1 MHz
4.13 Transmit exclusion bandwidths for spurious measurements
When measuring transmit spurious emissions, an exclusion band centred on the wanted carrier is defined as 250 % of
the CSP. The minimum values of necessary bandwidth (Bn) applicable depend on the operating frequency of the
equipment as defined in CEPT/ERC/Recommendation 74-01 [i.2]. The combination of 250 % of the CSP and these
necessary bandwidths result in the following transmit exclusion bands for spurious me
