3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
Adjacent Channel Leakage power Ratio (ACLR): ratio of the on-channel transmit power to the power measured in
one of the adjacent channels with no active channel in the adjacent channel
NOTE: In the present document this definition also applies to an unwanted signal at a specified frequency offset
in a non-adjacent channel.
Adjacent Channel Selectivity (ACS): measure of the capability of the receiver to receive a wanted modulated signal
without exceeding a given degradation due to the presence of an unwanted signal which differs in frequency from the
wanted signal by an amount equal to the adjacent channel separation for which the equipment is intended
NOTE 1: In the present document adjacent channel selectivity is determined by the onset of picture degradation.
NOTE 2: The interference power I is equal to the licensed power of the interferer. This definition does not have the
same meaning as the term "Adjacent Channel Selectivity" (ACS) used in other organizations such as ITU,
CEPT, and in co-existence studies. The adjacent channel selectivity in the present document is equivalent
to the measured I/C ratio.
NOTE 3: In the present document this definition also applies to an unwanted signal at a specified frequency offset
in a non-adjacent channel.

SIST EN 303 340 V1.2.1:2020

blocking or desensitization: measure of the capability of the receiver to receive a wanted modulated signal without
exceeding a given degradation due to the presence of an unwanted signal at any frequency other than those of the
spurious responses or of the adjacent channels
NOTE 1: In the present document receiver blocking is determined by the onset of picture degradation.
NOTE 2: The wanted signal level in the blocking tests of the present document is set at the specified receiver
sensitivity level plus 6 dB.
broadcast receiver: digital terrestrial television broadcast receiver comprising of at least a tuner and demodulator
broadcast receiver tuner port: DTT receiver tuner RF input connector
licensed power: highest rms power of the active portions of the signal measured over a specific time period
NOTE: In the case of interference power measurements, this is the reference power used for I/C calculations in
the present document. Typically for cases of LTE interference, this power is measured with a spectrum
analyser in zero span with a gated power measurement function and rms detector over a period equal to
an LTE symbol time. Alternatively it can be calculated by measuring the long term rms power and adding
the appropriate LAPR from table 5.
long term rms power: rms power of the signal measured over a period long enough to smooth out any fluctuations in
the signal power over time such as those due to transmission bursts
NOTE: This can be measured on an average power meter with an input filter time constant set high enough to
average out fluctuations in the measured signal power or alternatively using a spectrum analyser with
settings shown in table D.1.
onset of picture degradation: minimum time between successive errors in the displayed video is 15 seconds
radio equipment: product or relevant component thereof capable of communication by means of the emission and/or
reception of radio waves utilizing the spectrum allocated to terrestrial/space radio communication
NOTE: For the purposes of the present document the radio equipment is a digital terrestrial television broadcast
receiver comprising of at least a tuner and demodulator.
receiver overloading: interfering signal level expressed in dBm, above which the receiver begins to lose its ability to
discriminate against interfering signals at frequencies differing from that of the wanted signal due to the onset of strong
non-linear behaviour
NOTE 1: In the present document the overload level is determined by the onset of picture degradation.
NOTE 2: Above the overloading level the receiver will behave in a non-linear way, but does not necessarily fail
immediately depending on the receiver and interference characteristics.
sensitivity: maximum usable sensitivity is defined as the minimum receiver Radio Frequency (RF) input signal level or
field strength able to produce a specified analogue SINAD ratio or Bit Error Ratio (BER), or other specified output
performance which depends on this input signal level
NOTE: In the present document receiver sensitivity is determined by the onset of picture degradation.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
Adjacent Channel Leakage power Ratio (ACLR): ratio of the on-channel transmit power to the power measured in
one of the adjacent channels with no active channel in the adjacent channel
NOTE: In the present document this definition also applies to an unwanted signal at a specified frequency offset
in a non-adjacent channel.
Adjacent Channel Selectivity (ACS): measure of the capability of the receiver to receive a wanted modulated signal
without exceeding a given degradation due to the presence of an unwanted signal which differs in frequency from the
wanted signal by an amount equal to the adjacent channel separation for which the equipment is intended
NOTE 1: In the present document adjacent channel selectivity is determined by the onset of picture degradation.
NOTE 2: The interference power I is equal to the licensed power of the interferer. This definition does not have the
same meaning as the term "Adjacent Channel Selectivity" (ACS) used in other organizations such as ITU,
CEPT, and in co-existence studies. The adjacent channel selectivity in the present document is equivalent
to the measured I/C ratio.
NOTE 3: In the present document this definition also applies to an unwanted signal at a specified frequency offset
in a non-adjacent channel.
ETSI
---------------------- Page: 8 ----------------------
9 ETSI EN 303 340 V1.2.1 (2020-09)
blocking or desensitization: measure of the capability of the receiver to receive a wanted modulated signal without
exceeding a given degradation due to the presence of an unwanted signal at any frequency other than those of the
spurious responses or of the adjacent channels
NOTE 1: In the present document receiver blocking is determined by the onset of picture degradation.
NOTE 2: The wanted signal level in the blocking tests of the present document is set at the specified receiver
sensitivity level plus 6 dB.
broadcast receiver: digital terrestrial television broadcast receiver comprising of at least a tuner and demodulator
broadcast receiver tuner port: DTT receiver tuner RF input connector
licensed power: highest rms power of the active portions of the signal measured over a specific time period
NOTE: In the case of interference power measurements, this is the reference power used for I/C calculations in
the present document. Typically for cases of LTE interference, this power is measured with a spectrum
analyser in zero span with a gated power measurement function and rms detector over a period equal to
an LTE symbol time. Alternatively it can be calculated by measuring the long term rms power and adding
the appropriate LAPR from table 5.
long term rms power: rms power of the signal measured over a period long enough to smooth out any fluctuations in
the signal power over time such as those due to transmission bursts
NOTE: This can be measured on an average power meter with an input filter time constant set high enough to
average out fluctuations in the measured signal power or alternatively using a spectrum analyser with
settings shown in table D.1.
onset of picture degradation: minimum time between successive errors in the displayed video is 15 seconds
radio equipment: product or relevant component thereof capable of communication by means of the emission and/or
reception of radio waves utilizing the spectrum allocated to terrestrial/space radio communication
NOTE: For the purposes of the present document the radio equipment is a digital terrestrial television broadcast
receiver comprising of at least a tuner and demodulator.
receiver overloading: interfering signal level expressed in dBm, above which the receiver begins to lose its ability to
discriminate against interfering signals at frequencies differing from that of the wanted signal due to the onset of strong
non-linear behaviour
NOTE 1: In the present document the overload level is determined by the onset of picture degradation.
NOTE 2: Above the overloading level the receiver will behave in a non-linear way, but does not necessarily fail
immediately depending on the receiver and interference characteristics.
sensitivity: maximum usable sensitivity is defined as the minimum receiver Radio Frequency (RF) input signal level or
field strength able to produce a specified analogue SINAD ratio or Bit Error Ratio (BER), or other specified output
performance which depends on this input signal level
NOTE: In the present document receiver sensitivity is determined by the onset of picture degradation.

sensitivity level plus 6 dB.
broadcast receiver: digital terrestrial television broadcast receiver comprising of at least a tuner and demodulator
broadcast receiver tuner port: DTT receiver tuner RF input connector
licensed power: highest rms power of the active portions of the signal measured over a specific time period
NOTE: In the case of interference power measurements, this is the reference power used for I/C calculations in
the present document. Typically for cases of LTE interference, this power is measured with a spectrum
analyser in zero span with a gated power measurement function and rms detector over a period equal to
an LTE symbol time. Alternatively it can be calculated by measuring the long term rms power and adding
the appropriate LAPR from table 5.
long term rms power: rms power of the signal measured over a period long enough to smooth out any fluctuations in
the signal power over time such as those due to transmission bursts
NOTE: This can be measured on an average power meter with an input filter time constant set high enough to
average out fluctuations in the measured signal power or alternatively using a spectrum analyser with
settings shown in table D.1.
onset of picture degradation: minimum time between successive errors in the displayed video is 15 seconds
radio equipment: product or relevant component thereof capable of communication by means of the emission and/or
reception of radio waves utilizing the spectrum allocated to terrestrial/space radio communication
NOTE: For the purposes of the present document the radio equipment is a digital terrestrial television broadcast
receiver comprising of at least a tuner and demodulator.
receiver overloading: interfering signal level expressed in dBm, above which the receiver begins to lose its ability to
discriminate against interfering signals at frequencies differing from that of the wanted signal due to the onset of strong
non-linear behaviour
NOTE 1: In the present document the overload level is determined by the onset of picture degradation.
NOTE 2: Above the overloading level the receiver will behave in a non-linear way, but does not necessarily fail
immediately depending on the receiver and interference characteristics.
sensitivity: maximum usable sensitivity is defined as the minimum receiver Radio Frequency (RF) input signal level or
field strength able to produce a specified analogue SINAD ratio or Bit Error Ratio (BER), or other specified output
performance which depends on this input signal level
NOTE: In the present document receiver sensitivity is determined by the onset of picture degradation.

1 Scope
The present document specifies technical characteristics and methods of measurements for digital terrestrial television
broadcast receivers fitted with an external antenna input (tuner port) capable of receiving DVB-T and/or DVB-T2
signals.
Receivers without external antenna connectors, receivers with diversity, and receivers intended for mobile or
automotive reception are not covered by the present document.
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.3] is given in annex A.
The present document includes considerations of interference from LTE transmissions in the 700 MHz and 800 MHz
bands and DTT transmissions in UHF band IV. The requirements of the installation system (antenna, feeder cable,
amplifiers, etc.) are not addressed.
Table 1: Broadcast frequency bands
Broadcast frequency bands
VHF III
UHF IV and V
There are country specific variations of frequency usage for digital terrestrial television reception and other users such
as mobile broadband.
The tests in the present document only apply if the DTT broadcast receiver supports the wanted signal configuration
used by the test in question. The applicable tests are summarized in annex E, table E.1.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
Adjacent Channel Leakage power Ratio (ACLR): ratio of the on-channel transmit power to the power measured in
one of the adjacent channels with no active channel in the adjacent channel
NOTE: In the present document this definition also applies to an unwanted signal at a specified frequency offset
in a non-adjacent channel.
Adjacent Channel Selectivity (ACS): measure of the capability of the receiver to receive a wanted modulated signal
without exceeding a given degradation due to the presence of an unwanted signal which differs in frequency from the
wanted signal by an amount equal to the adjacent channel separation for which the equipment is intended
NOTE 1: In the present document adjacent channel selectivity is determined by the onset of picture degradation.
NOTE 2: The interference power I is equal to the licensed power of the interferer. This definition does not have the
same meaning as the term "Adjacent Channel Selectivity" (ACS) used in other organizations such as ITU,
CEPT, and in co-existence studies. The adjacent channel selectivity in the present document is equivalent
to the measured I/C ratio.
NOTE 3: In the present document this definition also applies to an unwanted signal at a specified frequency offset
in a non-adjacent channel.
