able for the I-branch and the Q-branch of the signal. If the limits are set, they are indi-
cated by the red dashed lines.

The number of displayed bars is determined by the selected spreading factor (SF).
Channels with a spreading factor smaller than the displayed SF occupy bars at several
adjacent codes. The figure above shows three channels:
●
Reverse Rate Indicator Channel (R-RRI), W
0
32
, I-Signal, code 0
●
Reverse Fundamental Channel (R-FCH), W
4

, Q-Signal, 2 bars
●
Reverse Supplemental Channel (R-SCH0), W

2
, Q-Signal, 16 bars
Bars for active code channels are colored. Bars for inactive code channels are gray.
The "Table View" provides scalar results of I- and Q- signals and statistical information.
The code channels can be sorted in two ways, as hadamard matrix or according to the
OVSF code tree (see

Multi Evaluation Detailed Views: Spectrum
The spectrum view displays power spectrum, Adjacent Channel Power (ACP) and
Occupied Bandwidth (OBW) results in a single diagram. It is visible if either the ACP or
OBW view is assigned.
