ETSI ETSI EN 303 340 V1.1.1 (2016-05) 6 1 Scope The present document applies to 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. The present document contains the requirements for digital terrestrial television broadcast receivers to meet the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. 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.

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. SIST EN 303 340 V1.1.1:2016
ETSI ETSI EN 303 340 V1.1.1 (2016-05) 8 NOTE 3: In the present document this definition also applies to an unwanted signal at a specified frequency offset in a non-adjacent channel. 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. 3.2 Symbols For the purposes of the present document, the following symbols apply: C Wanted signal GC Coupling Gain
