For the purposes of the present document either terms are assumed and are completely interchangeable. CHannel Separation (CHS): CHannel Separation (CHS) is taken as XS/2 for alternated frequency channel arrangements according to Recommendation ITU-R F.1191-1 [i.3] and XS for co-channel and interleaved frequency channel arrangements as defined by Recommendation ITU-R F.746-3 [i.4], XS is the radio-frequency separation between the centre frequencies of adjacent radio-frequency channels on the same polarization and in the same direction of transmission operating frequency range: range(s) of radio frequencies covered by the Equipment Under Test (EUT) without any change of units Repeater Station (RS): radio repeater outstations with or without subscriber interfaces Terminal Station (TS): outstations with subscriber interfaces SIST EN 301 489-4 V3.2.1:2019
