Page 22: Channel Tuning
PROPOWER-5 tunes it at its central frequency. Digital channels power measurement is carried out by means of an integration method. The PROPOWER-5 divides the bandwidth of the channel (CHANNEL BW) in sections of 230 kHz (4 by each MHz approximately) and measures the contribution of each one to the total power of the channel. - Page 23 2.5 MHz, in the relative mode of measurement the PROPOWER-5 will take as value for NOISE FREQ. = 1.25 MHz. Note that this method can cause erroneous measures in the measurement of the channels.
-
Page 24: Frequency Tuning
Remark: When switching from frequency to channel, if the tuned frequency does not correspond to any channel, the PROPOWER-5 will search for the channel nearest to this frequency and will stay tuned to this channel. This operation may take a few moments. -
Page 25: Spectrum Analyser Operating Mode
Finally, ∆FCH parameter allows to set the frequency offset for the channel tuning (PROPOWER-5 admits values from 2.00 to —2.00 to MHz), i.e. the displacement of the channel tuning frequency for those channels that present a central frequency displaced respect to the one of the corresponding standard system. -

Since on this operation mode the PROPOWER-5 holds on the screen the maximum measured value (through a dotted line), after making several measurements over the band, it will be possible to detect impulsive type interferences. It is advised to previously define a reference line which actuates as a maximum noise threshold (-10 dBm on previous figure). -

USER’S MANUAL. PROPOWER-5 APPENDIXES APPENDIX A.- FREQUENCY OFFSET ADJUSTMENT TUNING ANALOGUE AND DIGITAL CHANNELS. It is possible to introduce an offset of the tuning central frequency for the channels defined in each channel plan using the ∆FCH parameter (± 2 MHz). Therefore, it is possible to adapt the measures to irregular tunings, due to small displacements on channel central frequencies that are defined by the standard channel plan. -

USER’S MANUAL. PROPOWER-5 APPENDIX B.- EVALUATION OF THE FREQUENCY RESPONSE OF MAINS VOLTAGE NETWORKS (LT) FOR PLC TRANSMISSION The Power Line Communication technology (PLC) uses the electrical distribution lines for the transmission of information in broadband. From the distribution centers up to each subscriber the energy is distributed as low frequency alternate current (50 or 60 Hertz) by means of a Low Voltage between 220 and 440 V. - Page 38 Measurement procedure Connect the PROPOWER-1 generator in the point of measurement and to activate Connect the PROPOWER-5 analyser in the different points of connection. Verify if the measured spectrum presents acceptable insertion losses, according to the preset tolerance levels for each section that allow their use in the transmission of PLC signals.
