ports
6.1 General requirements
The PLC port of the EUT shall comply with the following requirements:
In any operating condition, the unsymmetrical disturbances from the PLC port shall not exceed the
disturbance limits given in Table 1 between 150 kHz and 1,606 5 MHz using the methods and procedures
given in 9.1.
When user data is being transmitted by the PLC port the disturbances from the PLC port may exceed the
disturbance limits of Table 1 at frequencies between 1,606 5 MHz and 30 MHz provided that within
— all the excluded frequency ranges given in Table A.1, the level of the transmitted signals shall comply
with the disturbance limits given in Table 1 using the methods and procedures given in 9.1,
— all the excluded frequency ranges given in Table A.2, the level of the transmitted signals shall comply
o either with the disturbance limits given in Table 1 using the methods and procedures given in 9.1,
o or with the dynamic frequency exclusion requirements given in 6.2.
Without user data transmission, the unsymmetrical disturbances from the PLC port shall comply with the
disturbance limits given in Table 1 between 150 kHz and 30 MHz using the methods and procedures given
in 9.1.
The maximum transmitted signal from the PLC port shall not exceed the maximum values given in Table 2
measured using the methods and procedures given in 9.2.

NOTE The transmit power management function of an AE should operate in the same way as the EUT
otherwise the signal of the AE may dominate and cause erroneous results during measurement.
6.2 Specific requirements for dynamic frequency exclusion
Within 15 s of a ‘valid’ HF radio broadcast service being present within the excluded frequency band given in
Table A.2, the transmitted PLC signal level shall not exceed a symmetrical voltage level of 56 dB(µV) (AV) in
a 9 kHz resolution bandwidth.
NOTE 1 This level of the symmetrical voltage is derived from the EN 55022 Mains Conducted Class B disturbance
limit (5 MHz to 30 MHz), which is U = 50 dB(µV) (Resolution Bandwidth 9 kHz, AV).
AMN
The transmitted PLC signal shall avoid using the frequency of an identified radio broadcast service. The
minimum width of the excluded frequency band shall be 10 kHz (± 5 kHz centred on the carrier frequency of
the broadcast signal). The excluded frequency band shall also comply with the requirements of Figure 1 in
order to avoid adjacent channel interference, with respect to AM / DRM protection ratios as defined in ITU-R
Recommendations BS.560-3, BS.1615 and BS.703, from transmissions outside the notch.
If several neighbouring radio broadcast services are identified or a digital (DRM) service occupying more
than a single conventional channel, the width of the excluded frequency range shall be increased, scaled to
integer multiples of 5 kHz.
NOTE 2 Usually, the channels of radio broadcast services are allocated with a minimum spacing of 5 kHz. Also, the
centre frequency is a multiple of 5 kHz.
The excluded frequency band shall remain excluded continuously for the entire duration that the ‘valid’ radio
broadcast service is present. After the detection of a ‘valid’ radio broadcast service has ceased, the excluded
frequency band shall remain excluded for at least 3 additional minutes.

7 Requirement for radiated disturbances
The EUT shall comply with the Class B limits, using the measurement conditions and the methodology
defined in EN 55022 for radiated disturbances.
8 Measurement conditions for PLC ports
The measurement of PLC ports shall be performed in conformance with EN 55022:2010, Clause 8.
The tests requiring the PLC modem function to be active shall be performed with the condition of PLC
utilisation in excess of 10 % and with the transmit signal set at its maximum level maintained for a minimum
of 250 ms. As an example, the transmission of a large data file could be used to exercise the port. Where
this is not possible an appropriate configuration should be used that ensures the PLC transmission is active
for a period of time long enough to allow for repeatable measurements in this state.
No connection shall be made to any AC mains output port.
9 Measurement methods and procedures for PLC ports
9.1 Conducted unsymmetrical disturbances
The PLC port of the EUT shall be assessed using an AMN in accordance with EN 55016-1-2:2004, 4.3, the
measurement method given in EN 55022:2010, Clause 9, for the mains ports and the arrangement shown in
Figure 2 below for frequencies between 150 kHz and 30 MHz.
---------------------- Page: 13 ----------------------
SIST EN 50561-1:2014
EN 50561-1:2013 - 12 -
The coupling system (see Figure 3) shall
a) allow the EUT to be exercised by the AE,
b) have a sufficient loss to ensure signals from the AE do not influence the measurement result,
c) ensure that the EUT can transmit at its maximum power level.
The coupling system is required for
— providing a defined (symmetric) insertion loss between the EUT and AE,
— stabilisation of the differential mode impedance,
— attenuation of the differential mode signal of the AE,
— isolation of the common mode signal of the AE,
— filtering of the differential- and common mode signal from the mains.
Figure 3 shows an example of a coupling unit with a nominal insertion loss of 40 dB.
Measurements in the following operating conditions and configurations shall be performed:
1) with the PLC modem function of the EUT active and communicating to an associated PLC apparatus
(AE) exercised in accordance with Clause 8, using its maximum transmit power the disturbance levels
shall be measured in the frequency range from 150 kHz to 30 MHz. Above 1,606 5 MHz only the
disturbances within the appropriate excluded frequency ranges need to be compared with the limits;
2) after completion of step 1, the exchange of user data exercising the EUT shall be terminated. Without
user data transmission, the disturbance levels shall be measured between 150 kHz – 30 MHz.
NOTE 1 Distance from AE to the reference ground plane (vertical or horizontal) is not critical.
NOTE 2 Cable length between EUT and CS is 0,8 m (± 0,05 m).

9.2 Dynamic power control
The transmitted symmetrical signal from the PLC port of the EUT shall be measured for frequencies between
1,606 5 MHz and 30 MHz in order to ensure that the maximum transmit signal levels are not exceeded and
to ensure the presence of a dynamic power control function. The PLC port shall be exercised in accordance
with the operating conditions given in Clause 8. The measurements shall be made using a peak and an
average detector; the detectors shall be in accordance with the requirements of EN 55016-1-1 including the
9 kHz requirement for the 6 dB bandwidth. An example test arrangement is given in Figure 4.
The transmit signal level shall be measured at all PLC transmission frequencies, with a symmetrical insertion
loss between EUT and AE of 10 dB, 20 dB, 40 dB and 50 dB.

Evropski predgovor
Ta dokument (EN 50561-1:2013) je pripravil tehnični odbor CLC/TC 210 "Elektromagnetna združljivost
(EMC)".
Določena sta bila naslednja datuma:
– zadnji datum, do katerega mora ta dokument dobiti (dop) 2014-10-09
status nacionalnega standarda bodisi z objavo
istovetnega besedila ali z razglasitvijo
– zadnji datum, ko je treba razveljaviti nacionalne (dow) 2016-10-09
standarde, ki so s tem dokumentom v nasprotju
Ta dokument je bil pripravljen v okviru mandata, ki sta ga Evropska komisija in Evropsko združenje za
prosto trgovino dala CENELEC in podpira bistvene zahteve evropskih direktiv.
Povezava z evropskimi direktivami je navedena v dodatku ZZ, ki je sestavni del tega dokumenta.
Področje uporabe je razširjeno na celotno radiofrekvenčno območje od 9 kHz do 400 GHz, vendar so
meje opredeljene samo v omejenih frekvenčnih pasovih, ki se štejejo za zadostne za doseganje
ustreznih nivojev emisij za zaščito radijskih oddaj in telekomunikacijskih storitev ter za omogočanje
namenskega delovanja drugim aparatom na primerni razdalji.

OPOMBA: Funkcija upravljanja oddajne moči pripadajoče opreme mora delovati na enak način kot
preskušanec, sicer signal pripadajoče opreme prevlada in povzroči napačne rezultate meritev.
6.2 Posebne zahteve za dinamično izločitev frekvence
V 15 sekundah "veljavne" visokofrekvenčne (VF) radiodifuzijske storitve, ki je znotraj izločenega
frekvenčnega pasu, navedenega v preglednici A.2, nivo signala PLC ne sme preseči nivoja simetrične
napetosti 56 dB(μV) (AV) pri 9 kHz-ni delitvi pasovne širine.
OPOMBA 1: Ta nivo simetrične napetosti izhaja iz EN 55022 kot mejna vrednost prevajane motnje po električnem omrežju
razreda B (5 MHz do 30 MHz), kjer je U = 50 dB(μV) (razdelba pasovne širine na 9 kHz, AV).
AMN
Oddani signal PLC se mora izogibati uporabi frekvence identificirane radiodifuzijske storitve. Najmanjša
širina izločenega frekvenčnega pasu mora biti 10 kHz (± 5 kHz okoli nosilne frekvence radiodifuzijskega
signala). Izločeni frekvenčni pas mora ustrezati zahtevam na sliki 1, da se glede na zaščitna razmerja
AM/DRM, definirana v priporočilih ITU-R BS.560-3 in BS.703, izogne motenju sosednjega kanala pri
oddajanjih/prenosih zunaj komutacijskih zarez.
Če je v bližini identificiranih več radiodifuzijskih ali digitalnih storitev (DRM), ki zasedajo več kot en
konvencionalni kanal, je treba povečati širino izločenega frekvenčnega območja na celoštevilčni
večkratnik 5 kHz.
OPOMBA 2: Navadno se kanali za radiodifuzijske storitve dodeljujejo z najmanjšim razmikom 5 kHz. Prav tako je srednja
frekvenca večkratnik 5 kHz.
Izločeni frekvenčni pas mora ostati izločen ves čas, dokler je prisotna "veljavna" radiodifuzijska storitev.
Po zaznavi prenehanja "veljavne" radiodifuzijske storitve mora izločeni frekvenčni pas ostati izločen še
vsaj 3 dodatne minute.

7 Zahteve za sevane motnje
Preskušanec mora ustrezati mejnim vrednostim razreda B za sevane motnje ob upoštevanju merilnih
pogojev in metodologije, določenih v EN 55022.
8 Merilni pogoji za porte PLC
Merjenje portov PLC se izvaja po EN 55022:2010, točka 8.
Preskuse, pri katerih se zahteva aktivnost modema PLC, je treba izvajati pod pogojem, da izkoristek
naprave PLC presega 10 %, pri čemer je prenosni signal nastavljen na najvišji nivo, kjer se vzdržuje
vsaj 250 ms. Kot primer se lahko za preskus porta uporabi prenos obsežne datoteke. Če to ni mogoče,
naj se uporabi ustrezna konfiguracija, s katero se zagotovi, da je prenos PLC aktiven dovolj dolgo, da
se meritve lahko v tem stanju ponovijo.
Na izhod za izmenično napajanje ni dovoljeno povezati nobenega priključka.
9 Merilne metode in postopki za porte PLC
9.1 Prevajane nesimetrične motnje
Port PLC na preskušancu je treba oceniti z uporabo umetnega omrežja (AMN) v skladu z EN 55016-1-
2:2004, točka 4.3, pri čemer se uporabita merilna metoda, navedena v EN 55022:2010, točka 9, za
omrežne porte in shema, prikazana na sliki 2 spodaj, za frekvence med 150 kHz in 30 MHz.

---------------------- Page: 15 ----------------------
SIST EN 50561-1 : 2014
Sklopni sistem (glej sliko 3) mora:
a) dovoliti preskušancu, da ga preskuša pripadajoča oprema,
b) imeti dovolj veliko slabljenje, da signali iz pripadajoče opreme ne vplivajo na merilni rezultat,
c) zagotoviti, da lahko preskušanec oddaja z največjim nivojem moči.
Sklopni sistem je potreben za:
– zagotovitev definiranega (simetričnega) vnesenega slabljenja med preskušancem in pripadajočo
opremo,
– stabilizacijo diferenčne impedance,
– slabljenje diferenčnega signala pripadajoče opreme,
– ločitev sofaznega (nesimetričnega) signala pripadajoče opreme,
– filtriranje protifaznega (diferenčnega) in sofaznega signala iz omrežja.
Slika 3 prikazuje primer sklopne enote z nazivnim vnesenim slabljenjem 40 dB.
Meritve je treba izvesti pri naslednjih obratovalnih pogojih in konfiguracija

42 1 Scope
43 This European standard specifies limits and methods of measurement of radio disturbance characteristics for
44 in-home communication apparatus that uses the low voltage power installation as the transmission medium.
45 The standard applies to equipment that transmits in the frequency range 1,7 MHz to 30 MHz.
46 Procedures are given for the measurement of signals generated by the equipment and limits are specified for
47 the frequency range 9 kHz to 400 GHz. No measurements need be performed at frequencies where no limits
48 are specified.
49 The intention of this publication is to establish uniform requirements for the radio disturbance level of the
50 equipment contained in the scope, to establish limits of disturbance, to describe methods of measurement
51 and to standardize operating conditions and interpretation of results.
