 Technical requirements of Digital Terrestrial Transmission System (DVB -T/T2) 
Receivers  
1- Scope  
This standard  specifies technical characteristics and methods of measurements for digital 
terrestrial television broadcast receivers fitted with an external antenn a 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 includes considerations of interference from LTE transmissions in 
the 700 MHz and 800 MHz bands and DTT transmissions in UHF band IV  (according to 
the Saudi National Frequency Plan ). The requirements of the installation system (antenna, 
feeder ca ble, amplifiers, etc.) are not addressed.

2- Normative References  
The following referenced documents are indispensable for the application of this docu ment.  
For dated references, only the edition cited applies. For undated references, the latest 
edition  of the referenced document (including any amendments) applies.  
 ETSI EN 303 340 V1.2.1  
 SASO -CITC -RI121  
 
3- Terms , Symbols,  and Abbreviations : 
3.1 Terms  
For the purposes of the present document, the following terms apply:  
3.1.1  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 channe l. 
 
NOTE : In the present document this definition also applies to an unwanted signal at a specified 
frequency offset in a non -adjacent channel.  
3.1.2  Adjacent Channel Selectivity (ACS) : a measure of the capability of the receiver to 
receive a wanted modul ated 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.  SASO STANDERD   SASO  XXXX:2024  
5 
  
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 Selec tivity" (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.  
3.1.3  blocking  or desensitization : a measure of the capability of th e 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 recei ver 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.  
3.1.4  Broadcast receiver : digital terrestrial tele vision broadcast receiver comprising of 
at least a tuner and demodulator broadcast receiver.  
3.1.5  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 spans 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 4.  
3.1.6 Long -term  RMS  power : RMS  power of the signal mea sured 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.  
3.1.7  Onset of picture degradation : minimum time between successive errors in the 
displayed video is 15 seconds.  
 
3.1.8  Radio equipment : product or releva nt 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 digit al terrestrial television 
broadcast receiver comprising of at least a tuner and demodulator.  
3.1.9  receiver overloading : interfering signal level expressed in dBm, above which the 
receiver begins to lose its ability to discriminate against interfering sig nals at frequencies 
differing from that of the wanted signal due to the onset of strong non -linear behaviour.  SASO STANDERD   SASO  XXXX:2024  
6 
 NOTE 1:  In the present document the overload level is determined by the onset of picture degradation.  
NOTE 2:  Above the overloading level the rec eiver will behave in a non -linear way but does not necessarily 
fail immediately depending on the receiver and interference characteristics.  
3.1.10  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 on set of picture degradation.

 4.4 Adjacent Channel Selectivity  
4.4.1 Definition  
In the p resent document, adjacent channel selectivity (I/C) is defined as the 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. In the present document , adjacent channel selectivity is determined 
by the onset of picture degradation.  
NOTE 1: The interference power I is e qual 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 th e present document is 
equivalent to the measured I/C ratio.  
NOTE 2: In the present document this definition also applies to an unwanted signal at a specified frequency 
offset in a non -adjacent channel.  SASO STANDERD   SASO  XXXX:2024

 Annex B (informative): Justification of omitted receiver parameters  
B.1 Receiver parameters omitted   
B.1.1 Co -channel rejection  
Receiver co -channel rejection is a measure of the capability of a receiver to receive a 
wanted sign al, without exceeding a given degradation, due to the presence of an unwanted 
signal, both signals being at the nominal frequency of the receiver.   
A specific test for co -channel rejection is not included because, in the TV bands, co -channel 
interference is other DTT signals, possibly from neighbouring countries or distant MFN 
transmitters (at a low level). Since DTT signals are Gaussian in nature, the co -channel 
performance is strongly correlated to AWGN performance. See measured data in table G.1. 
Theref ore, weaknesses in receiver co -channel rejection will result in degraded sensitivity 
test results (table 4 of the present document).
