b) upon receipt of any single pulse which has no amplitude variations approximating a normal interrogation condition. 3.1.1.7.3 Dead time. After recognition of a proper interrogation, the transponder shall not reply to any other interrogation, at least for the duration of the reply pulse train. This dead time shall end no later than 125 microseconds after the transmission of the last reply pulse of the group. 3.1.1.7.4 SUPPRESSION Note.— This characteristic is used to prevent replies to interrogations received via the side lobes of the interrogator antenna, and to prevent Mode A/C transponders from replying to Mode S interrogations. 3.1.1.7.4.1 The transponder shall be suppressed when the received amplitude of P2 is equal to, or in excess of, the received amplitude of P1 and spaced 2.0 plus or minus 0.15 microseconds. The detection of P3 is not required as a prerequisite for initiation of suppression action. 3.1.1.7.4.2 The transponder suppression shall be for a period of 35 plus or minus 10 microseconds. 3.1.1.7.4.2.1 The suppression shall be capable of being reinitiated for the full duration within 2 microseconds after the end of any suppression period. Chapter 3 Annex 10 — Aeronautical Telecommunications 3-5 22/11/07 3.1.1.7.5 RECEIVER SENSITIVITY AND DYNAMIC RANGE 3.1.1.7.5.1 The minimum triggering level of the transponder shall be such that replies are generated to at least 90 per cent of the interrogation signals when:
