WP2‐005.030.000‐SRS‐002Revision : BIdent Requirement Applicability Parent VerificationSYS_REQ_5340Wind velocities. SKA1 equipmentshall be able to survive windvelocities up to 160 km/hr (TBC),and shall operate within normalspecification ranges for windvelocities up to 40 km/hr (TBC).TBD5.1.5 Radio Frequency InterferenceProtection and measures against interfering signals from outside the instrumentIdent Requirement Applicability Parent VerificationSYS_REQ_5410Damaging interference levels.SKA1 shall not be damaged by RFIsignals less than TBD V/m.TBDIdent Requirement Applicability Parent VerificationSYS_REQ_5420EM immunity. SKA1 shall not besusceptible to RFI signals, in‐bandor out‐band, other than via thereceptors.TBDIdent Requirement Applicability Parent VerificationSYS_REQ_5430ADC clipping. The dynamic rangeof the ADC’s in the SKA1 shall besuch that no clipping will occur.Clipping occurs when the range ofthe input signal voltages to theADC is larger than the ADCvoltage range. The number ofADC bits shall therefore besufficient to prevent clipping dueto strong interfering signals suchas aircraft Distance MeasuringEquipment (DME) and satellitesignals.TBD5.1.6 Electro Magnetic CompatibilityDuring each phase of the SKA1 life, from equipment integration until its end of life, the instrumentshall neither cause disturbance to other systems, nor suffer loss of performance due to othersystems or to the RFI environment.2011‐02‐14 Page 41 of 58
