Enhanced Functions For Digital Standard 3GPP W-CDMA (FDD) SMIQ
1125.5555.03 2.256 E-9
DPCCH POWER
Sets the channel power (-60 dB to 0 dB) of the DPCCH. If the EXTERNAL
POWER CONTROL STATE switch is set to ON, this power is also the start
power for power control.
Note : Starting the ADJUST TOTAL POWER menu parameter at the top
menu level of 3GPP W-CDMA adapts all the channel powers
(POWER DB parameter) of the mobile stations (and, thus, also the
POWER START values of the set enhanced channel) so that the
average overall power of all the activated channels is 0 dB with
reference to the LEVEL indicated in the SMIQ display.

SYMBOL RATE
Display parameter indicating the symbol rates of the individual uplink
enhanced channels.
2.15.3.3 Display of External Power Control Mode of Four Enhanced Channels
The current External Power Control mode of the four enhanced channels is displayed here. The
deviation of the channel power (= ∆POW) of the set POWER START caused by the external power
control mechanism is displayed in graphical form.
The window is shown in the SMIQ display after calculating the 3GPP W-CDMA signal triggered by
STATE = ON or MOD ON. The window is blanked out after pressing the RETURN key to be able to
operate the SMIQ during the signal output.
Since a realtime update of the window in the timeslot (= 0.667 ms) is not possible for reasons of speed,
an update can be performed in a more coarse time interval. Fast channel power changes are not
displayed but the settled state of the control loop can be recognized very easily by the user.
