A special pattern editor is displayed.IEC/IEEE-bus commands::SOUR:W3GP:MST2:DPCC:FBI:DATA PATT:SOUR:W3GP:MST2:DPCC:FBI:PATT #H3F, 8MISUSE TPC FOROUTPUT POWERCONTROLTPC bits are used for W-CDMA to inform the called station if the transmitpower is being increased or decreased. If this option is activated, the givenpattern is being misused to vary one’s own transmit power over time. For eachslot, one bit of this pattern is taken to increase (bit = 1) or decrease (bit = 0)the channel power by the stated power step (POWER STEP TPC). The upperlimit is 0 dB and the lower –60 dB.The following envelope occurs at a channel power of 0 dB, a power step of1.0 dB, the pattern "001110100000011" and TPC Pattern ReadOut ModeContinuous:Fig. 2-123Dynamic change of channel power (continuous)Note: Observe that the power change (as specified in the standard) isalways performed at the beginning of the slot pilot field.IEC/IEEE-bus command :SOUR:W3GP:MST1:DPCC:TPC:MIS ONTPC POWER STEPSize of power step in dB, if option MISUSE TPC FOR OUTPUT POWER CONTROLis activated.The range is –10.0 dB to +10.0 dB.IEC/IEEE-bus command :SOUR:W3GP:MST1:DPCC:TPC:PST 1.01125.5555.03 2.206E-9
