WP2‐005.030.000‐SRS‐002Revision : B3.3 Spectral CharacteristicsThis section refers to the part of the spectrum to be observed with SKA 1 . It has an impact on theantenna and receiver specifications, but also on the dimensions of all digital processing.3.3.1 Operating FrequencyIdent Requirement Applicability Parent VerificationSYS_REQ_1110Electromagnetic frequencyrange. SKA1 shall be able tomeasure electromagneticradiation in a frequency rangefrom 70 MHz to 3 GHz.3.3.2 Instantaneous BandwidthMandatory [1] Table 8.1 TestIdent Requirement Applicability Parent VerificationSYS_REQ_1120Instantaneous bandwidth. SKA1shall have an instantaneousbandwidth, of:Fractional instantaneousbandwidth: 1 The SKA Phase 1shall be designed so that thefractional instantaneousbandwidth is comparable to theobserving frequency.Mandatory[1]Paragraph1.4.3 andTable 2.2TestIdent Requirement Applicability Parent VerificationSYS_REQ_1130Frequency band positioning. Itshall be possible to position thisband anywhere within theoperating frequency band, with apositioning accuracy as specifiedin SYS_REQ_1970 andSYS_REQ_1980. Theinstantaneous observablefrequency band is a contiguous(TBC) band selected from thetotal frequency range.MandatoryTestIdent Requirement Applicability Parent VerificationSYS_REQ_1140Band selection resolution. Theresolution with which the 500MHz and 1 GHz bands can beselected shall be TBD or less.MandatoryTest2011‐02‐14 Page 13 of 58
