8 Conditions – operation of exterior paging system transmitters

Spurious emissions when operating in 0°C to 60°C (1) If: (a) a radiocommunications transmitter is part of an exterior paging system; and (b) the ambient temperature is between 0°C and 60°C (inclusive); a person must not operate the transmitter unless: (c) each discrete spurious emission of the transmitter is not greater than -30 dBm at: (i) the radiofrequency output connector of the transmitter; and (ii) the input connector of the antenna; (d) the broad band noise floor of the transmitter, in a bandwidth of 16 kHz at frequency offsets greater than 300 kHz from the frequency on which the transmitter is authorised to operate, is not greater than -47 dBm. Out-of-band emissions when operating in 0°C to 60°C (2) If: (a) a radiocommunications transmitter is part of an exterior paging system; and (b) the ambient temperature is between 0°C and 60°C (inclusive); a person must not operate the transmitter otherwise than in accordance with subsection (3) or subsection (4). (3) A person operates a radiocommunications transmitter in accordance with this subsection if: (a) the power of the transmitter does not exceed 500 W EIRP; and (b) the out-of-band emissions of the transmitter are attenuated below the unmodulated carrier power: (i) for frequencies (the offset frequencies) between 12.5 kHz and 14 kHz from the frequency on which the transmitter is authorised to operate (the operating frequency) – by at least: Start formula open bracket 18 times f minus 202 close bracket dB end formula where: “f” means the absolute value of the difference between the offset frequency and the operating frequency in kHz; and (ii) for frequencies between 14 kHz and 39 kHz from the operating frequency – by at least 50 dB; and (iii) for frequencies greater than 39 kHz from the operating frequency – by at least 60 dB.

Note: Example for subparagraph (i): For a radiocommunications transmitter that is authorised to operate on 1000 kHz, for the offset frequency 1013 kHz, the out-of-band emission of the transmitter must be attenuated below the unmodulated carrier power by at least:

Note: (18 x (1013-1000) – 202) dB

Note: = 32 dB

(4) A person operates a radiocommunications transmitter in accordance with this subsection if: (a) the power of the transmitter is between 500 W and 1000 W (inclusive) EIRP; and (b) the out-of-band emissions of the transmitter are attenuated below the unmodulated carrier power: (i) for frequencies between 12.5 kHz and 14 kHz (the offset frequencies) from the frequency on which the transmitter is authorised to operate (the operating frequency) – by at least: Start formula open bracket 20 times f minus 227 close bracket dB end formula where: “f” means the absolute value of the difference between the offset frequency and the operating frequency in kHz; and (ii) for frequencies between 14 kHz and 39 kHz from the operating frequency – by at least 53 dB; and (iii) for frequencies greater than 39 kHz from the operating frequency – by at least 63 dB.
