Global modific

24、ations to EN 14908-3:2006 Clause 5.2 “Data Channel“ Shall be modified as follows: The channel occupies the 125 kHz to 140 kHz 9 kHz to 95 kHz frequency band, as defined in EN 50065-1, as a Binary Phase Shift Keyed (BPSK) modulated carrier. This channel is used to send protocol messages containing co

25、ntrol, status, configuration and diagnostic information. The signalling characteristics of the channel are described in Clause 6 of EN 14908-3:2006. Clause 5.6 “Surge Protection and Related Devices“ Shall be modified as follows: Certain surge protection and related frequency selective protection dev

26、ices may be installed on the power network. These devices may attenuate the CNP channel waveform sufficiently to prevent operation in part or the entire network. Precautions should be taken such that the device chosen does not substantially attenuate the signals in the 125 kHz to 140 kHz 9 kHz to 95

27、 kHz range. Clause 6.4 “PL Packet Timing“ Shall be modified as follows: As described in EN 14908-1, the protocol uses an interpacket spacing defined as a Beta1 time and randomising slots defined as Beta2 times. Beta1 is measured from the end of a packet to the beginning of the first Beta2 slot. The

28、CNP protocol and PL transceiver in combination shall produce a Beta1 time of 3,4ms 5,19 ms +/-0,1 ms and B2 times of 2,0ms 3,05 ms +/-0,1 ms each. For optimum communication between nodes, there should be 8 0 priority Beta2 slots. In addition, the transceiver shall meet the timing parameters defined

29、below and specified in Table 1. Carrier Detect - The time from when the beginning of the packet is at the receivers input until the receiver has detected carrier and caused P_Channel_Active to be set to true. Transmit Start Delay - The time from when P_Data_request is activated to when the beginning

30、 of the packet is initiated onto the power line. Table 1 - Transceiver Timing Specifications Parameter Specification Carrier Detect 1,7 ms max 2,93 ms max. Transmit Start Delay 100 s max 153 s max. ETSI ETSI TS 103 908 V1.1.1 (2011-10)7Clause 6.5.1 “Carrier Modulation“ Shall be modified as follows:

31、The transmitter shall be a differential driver capable of driving the specified signal on the PL network. Each bitis sent as NRZ data BPSK modulated on to a carrier. The carrier frequency shall be 131,579 kHz 86,232 kHz with a tolerance of200 PPM. The symbol rate is 5482,45 symbols/sec 3592,98 symbo

32、ls/sec with a tolerance of 200 PPM. Note that appropriate shaping shall be performed on the modulated waveform to meet the requirements in EN 50065-1 for conducted emissions. Clause 6.5.2 “Waveform Amplitude“ Shall be modified as follows: The amplitude of the carrier output voltage during packet tra

33、nsmission should be measured at 23 C 3 C using the test circuit shown in Figure 4. The V-network is an artificial network of (50 /(50 H+5 ) conforming to 8.2.1 of CISPR 16. The amplitude is measured using the tuned receiver at a frequency of 131,5 kHz 86,2 kHz with a peak detector and a 30 kHz resol

34、ution bandwidth. The tuned receiver using its peak detector should read the rms value of a sinusoid. The amplitude limits shall be met both with switch closed and with the switch open. The transmit voltage will be calculated using the following formula Vpp=2,828xVmeasured and dBV=20log10(Vmeasured).

35、 The transmit voltage Vmeasured shall be greater than 0 dBV (2,828 Vpp) and less than 11 dBV (10,0 Vpp) when the switch is open and greater than -12 dBV (0,7 Vpp) when the switch is closed.

37、S 103 908 V1.1.1 (2011-10)8Clause 6.6.1 “Receive Mode Effective Input Impedance“ Shall be modified as follows: The receive-mode effective input impedance shall be measured using the test circuit shown in Figure 5 and at an ambient temperature of 23 C 3 C. The V-network is an artificial network of (5

38、0 /(50 H+5 ) conforming to sub clause 8.2.1 of CISPR Publication 16. The receiver impedance is measured as follows. Set the signal generator to a sine wave of amplitude 5 V peak-to-peak at a frequency of 131,5 kHz 86,2 kHz. All measurements are made with a tuned receiver using a peak detector and a

39、30 kHz resolution bandwidth. The tuned receiver using its peak detector should read the rms value of a sinusoid. With the transceiver unplugged, measure the voltage (Voc) on the V-network 50 resistor (the signal generator provides this resistor with its internal termination) with the tuned receiver.

40、 The voltage Vocshould be 5,5 dBV 1dB (5,3 volts peak to peak 10%) where dBV is defined as dBV=20*Log10(Vpp/2,828). Next, with the transceiver plugged in and powered up in receive mode measure the voltage (Vic) on the V-network 50 resistor. The effective receive input impedance is calculated with th

41、e following formula where Zeis the effective receiver input impedance, Znis a constant value of 2919,Vocand Vicare the two voltages measured as described above (they shall be corrected for the 1/10 divider).

44、measure the PL transceivers immunity to interference at various frequencies. There are four three frequency bands of interference identified. Figure 7 depicts the four three bands and the performance specification. Power line noise is present throughout the entire frequency spectrum and generally in

45、creases in amplitude with decreasing frequencies. Commercial broadcast signals can be at very high levels and for the purposes of the present document are defined to be between 150 kHz and 500 kHz 1 MHz. European and North American AM broadcast is present at high levels because power lines act as an

46、tennas for radio broadcasts. The broadcast noise region for this test is defined to be between 500 kHz 150 kHz and 1 MHz. The power line modem noise band is defined to be between 100 kHz 95 kHz and 150 kHz (EN 50065-1 sub-bands 95 kHz to 125 kHz, 125 kHz to 140 kHz and 140 kHz to 148,5 kHz). Key: A

Referring to Figure 6

48、1, switches SW1 and SW2 are open. The receive level is set to -47 dBV on the 50 resistor of the V-network by adjusting R1 when the transmitter is sending packets. The signal generator is set to frequency and amplitudes as shown in Table 2. The frequency spacing is every 5 kHz from 10 kHz to 150 kHz

49、and every 50 kHz from 150 kHz to 1 MHz. The interfering tone level (Itone) is then measured with the tuned receiver. Then for each frequency and amplitude of tone the received packet error rate (PER%) shall be less than 2 %.
