Active and inactive channels are defined via the Channel Table Settings dialog box (Settings
softkey menu, Channel Table Settings softkey). The power values of the active and
unassigned channels are shown in different colors. In addition, codes with alias power can
occur. These codes obtain power components originating either from a spreading factor higher
than the base spreading factor or from the own and/or another antenna as a result of transmit
diversity.
The following colors are defined:
– Red: selected channel (Channel (Code) Number)
– Yellow: active channel
– Cyan: inactive channel
– Light blue: alias power of higher spreading factor
– Magenta: alias power as a result of transmit diversity
Note: If codes with alias power are displayed, set the highest base spreading factor using the Base
SF.
It is not recommended to select more detailed result displays (such as Channel Constell) for
unassigned codes, since the results are not valid.

Remote: CALC1:FEED "XPOW:CDP" (absolute code power)
Channel Table
Selects the Channel Table result display.
The Channel Table result display may contain up to 128 entries, corresponding to the highest
base spreading factor of 128. The total signal is taken into account over a single power control
group. You can set the number of PCGs by the Capture Length.
In the Channel Table result display, the channels are sorted according to channel type, i.e.
special channels like F-PICH, F-SYNC etc. first, then data channels (CHAN) and last inactive
channels (always shown as '---').
Within a group, channels are sorted according to the spreading factor and then according to
code number, also in ascending order. Within the code number, first active, then inactive
channels are listed. The selected channel (Channel (Code) Number) is marked in red. Active
and inactive data channels are defined via the Channel Table Settings dialog box (Settings
softkey menu, Channel Table Settings softkey).
