5. Tx In-band (L-band) Performance
A. Modulation Characteristics
(1) For purposes of the following sections the following definition of Tx carriers apply:
(a) Reference signal generator will be set for the following setup conditions:
(b) Data Source: PN
(c) Repeat: Continuous
(d) Phase Polarity: Normal
(e) Differential Data Encoding: Off
(2) The modulation characteristics for the applicable bearer type are shown in Table 2-2
where Channel Bandwidth is the Necessary Bandwidth.
