Table 1 provides a cross reference between these two essential parameters and the corresponding three technical requirements for equipment within the scope of the present document. To fulfil an essential parameter the compliance with all the corresponding technical requirements in Table 4.1 must be verified. Table 4.1: Cross references Essential parameter Corresponding technical requirements Conducted emissions from antenna port 4.2.2 Spurious emissions 4.2.3 Out-of-band emissions Radiated emissions from enclosure port 4.2.4 Cabinet radiation
4.2.2 Spurious emissions 4.2.2.1 Definition Emissions on a frequency or frequencies which are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission of information. These include harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products but exclude out of band emissions. For the purposes of the present document spurious emissions are emissions at frequencies outside the frequency range
f0 ± 14 MHz for 7 MHz channels, f0 ± 12 MHz for 8 MHz channels, where f0 is the centre frequency of the channel, irrespective of the number of carriers employed. 4.2.2.2 Limits Spurious emissions shall not exceed the values set out in Table 4.2 additionally shown in Figures 4.1 and 4.2, for the frequency range 9 kHz to 4,5 GHz. In the case of a DVB-T transmitter supplied without an internal bandpass output filter, the manufacturer shall specify the characteristics of the filter necessary to fulfil the spurious emission limits defined in Table 4.2. The manufacturer shall include this information in their test report.

Emissions on a frequency or frequencies immediately outside the necessary bandwidth but exclude spurious emissions. For the purposes of the present document out-of-band emissions are emissions at frequencies outside the necessary bandwidth and within the frequency ranges f0 ± 14 MHz for 7 MHz channels, f0 ± 12 MHz for 8 MHz channels, where f0 is the centre frequency of the channel, irrespective of the number of carriers employed. 4.2.3.2 Limits Out-of-band emissions shall not exceed the limits specified in Tables 4.3 and 4.4, additionally shown in Figures 4.3 and 4.4. Out-of-band emissions limits are given as mean power level measured in a 4 kHz bandwidth, where 0 dB corresponds to the mean output power. Unless otherwise declared by the manufacturer it shall be assumed that the EUT conforms to the non-critical case. For critical cases such as television channels adjacent to other services (low power or receive only) a spectrum mask with higher of out-of-channel attenuation may be needed. In the case of a DVB-T transmitter supplied without an internal bandpass output filter, the manufacturer shall specify the characteristics of the filter necessary to fulfil the out-of-band emission masks defined in Tables 4.3 and 4.4. The manufacturer shall include this information in their test report. Table 4.3: Out-of-band emission limits for DVB-T transmitter with output power ≥ 25 W Classification accordingly
