d) minus 79 dBW/m2 at 2.5 m (8 ft) above the runway surface, at the MLS datum point, or at the farthest point on the runway centre line which is in line of sight of the DME transponder antenna. Note uidance material relating to the ERP may be found in Attachment C and 3.5.4.1.5.4 The peak power of the constituent pulses of any pair of pulses shall not differ by more than 1 dB. 3.5.4.1.5.5 Recommendation The reply capability of the transmitter should be such that the transponder should be capable of continuous operation at a transmission rate of plus or minus pulse pairs per second (if aircraft are to be served) Note uidance on the relationship between number of aircraft and transmission rate is given in Attachment C 3.5.4.1.5.6 The transmitter shall operate at a transmission rate, including randomly distributed pulse pairs and distance reply pulse pairs, of not less than 700 pulse pairs per second except during identity. The minimum transmission rate shall be as close as practicable to 700 pulse pairs per second. For DME/P, in no case shall it exceed 1 200 pulse pairs per second. 3.5.4.1.6 Spurious radiation During intervals between transmission of individual pulses, the spurious power received and measured in a receiver having the same characteristics as a transponder receiver, but tuned to any DME interrogation or reply frequency, shall be more than 50 dB below the peak pulse power received and measured in the same receiver tuned to the reply frequency in use during the transmission of the required pulses. This provision refers to all spurious transmissions, including modulator and electrical interference. 3.5.4.1.6.1 DME N The spurious power level specified in 3.5.4.1.6 shall be more than 80 dB below the peak pulse power level. 3.5.4.1.6.2 DME P The spurious power level specified in 3.5.4.1.6 shall be more than 80 dB below the peak pulse power level. 3.5.4.1.6.3 ut of band spurious radiation At all frequencies from 10 to 1 800 MHz, but excluding the band of frequencies from 960 to 1 215 MHz, the spurious output of the DME transponder transmitter shall not exceed minus 40 dBm in any one kHz of receiver bandwidth. 3.5.4.1.6.4 The equivalent isotropically radiated power of any CW harmonic of the carrier frequency on any DME operating channel shall not exceed minus 10 dBm. 3.5.4.2 Receiver 3.5.4.2.1 Fre uency of operation The receiver centre frequency shall be the interrogation frequency appropriate to the assigned DME operating channel (see 3.5.3.3.3). 3.5.4.2.2 Fre uency stability The centre frequency of the receiver shall not vary more than plus or minus 0.002 per cent from the assigned frequency. 3.5.4.2.3 Transponder sensitivity 3.5.4.2.3.1 In the absence of all interrogation pulse pairs, with the exception of those necessary to perform the sensitivity measurement, interrogation pulse pairs with the correct spacing and nominal frequency shall trigger the transponder if the peak power density at the transponder antenna is at least: 2007/70/II. szám C a ter Annex 10 — Aeronautical Communications 23/11/06
