codes). A light blue section link is the bottom bar of the upper graph to the
whole of the lower graph (described below). The red line across the graph
represents the active channel threshold. The traffic channel displays in orange
color, the rest are in the color shown in the control view.
• In Full View, the lower-left graph shows the upper 256 of the 512 channels
(OVSFs or spread codes).
In Zoom View, the lower-left graph shows the power in the section highlighted
in light blue in the top-left graph. This is a selection of either 32, 64, or 128
codes.
• The top-right graph (Control View) shows the power in the control channels (see
Table below). The PICH and the S-CCPCH channels are only displayed if you
have enabled them using the Setup menu. For further details, see “Enabling
PICH and S-CCPCH” on page 564.
The bottom portion (Metrics View) displays the current measurement metrics.
NOTE In W-CDMA or W-CDMA (with HSDPA), the P-SCH and S-SCH are not assigned
spread codes and therefore do not appear in the code domain power display (Full
View). The E7495A/B features a control channel graph view (Control View) for
these two Sync channels to measure power only, since there is no spread code
associated with these channels. They have special non-orthogonal scrambling codes
and are only actually On 10% of the time
