SMIQ Enhanced Functions For Digital Standard 3GPP W-CDMA (FDD)

POWER UP RANGE
Dynamic range (0 to 30 dB) by which – with external power control mechanism
switched on – the channel powers of all activated enhanced channels can be
increased. The value POWER UP RANGE can be changed by POWER STEP.
If the dynamic range is exceeded, the warning MAX. POWER UP REACHED is
displayed.
The resulting external power control dynamic range (= POWER UP RANGE –
POWER DOWN RANGE) may be 30 dB at max. which is why the POWER UP
RANGE is limited as a function of the POWER DOWN RANGE.
IEC/IEEE-bus command :SOUR:W3GP:BST:ENH:EPOW:RANG:UP 10.0
POWER DOWN
RANGE
Dynamic range (0 to 30 dB) by which – with external power control mechanism
switched on – the channel powers of all activated enhanced channels can be
decreased. The value POWER UP RANGE can be changed by POWER STEP.
If the dynamic range is underranged, the warning MAX. POWER UP REACHED
is displayed.
The resulting external power control dynamic range (= POWER UP RANGE –
POWER DOWN RANGE) may be 30 dB at max. which is why the POWER
DOWN RANGE is limited as a function of the POWER UP RANGE.

POWER CONTROL
GRAPH ►
With this menu parameter selected, the display window is opened again and -
with external power control mechanism switched on - the "current" deviation of
the channel power from the set power start value of the corresponding
enhanced channels is displayed graphically(see section 2.15.3.3).
The display window is only shown if the EXTERNAL POWER CONTROL
switch is set to ON and if the specific POWER CONTROL switch is positioned
to UP or DOWN in the downlink for at least one enhanced channel.
Note : This window is opened automatically after calculation of the signals
triggered by STATE = ON or MOD ON but can be closed again
manually by the user. This menu parameter allows the insertion of
the window again without recalculating the signal.
Note: With Enhanced P-CCPCH/BCH State On in the downlink, only the DPCH is power-
controlled. The P-CCPCH always has the power set in the enhanced channel table.
