Values between 1 and 10 can beselected.IEC/IEEE-bus command :SOUR:W3GP:MST2:PCPC:PREP 3Power of the preamble components of the PCPCHs. The value range of thepower is from –60 dB to 0 dB.IEC/IEEE-bus command :SOUR:W3GP:MST2: PCPC:PPOW –5The power by which the preamble is increased from repetition to repetition canbe set. The value range is 0 dB to 10 dB.Note: The preamble power that can be entered at the top of the panel is thedestination power used in the last repetition of the preamble. If, forexample, a preamble power of 0 dB, a repetition of 3 and a powerstep of 3 dB are set, the following power sequence will be generated:IEC/IEEE-bus command :SOUR:W3GP:MST2:PCPC:PPOW:STEP 3DATA PART POWERCONTROL PARTPOWERSHARED RESOURCEMODEMESSAGE PARTLENGTHPower of the data components of the PCPCH.
