Multiple-View Display

Multiple-View Display
The W-CDMA and W-CDMA (w/ HSDPA) Tx analyzer multiple-view screens are divided into two sections in both the Zoom View (default and ) and in the Full View The upper portion contains three graphical views of your data, and the lower portion contains the measurement metrics.
The upper, graphical portion shows the following three views:

In Full View, the top-left graph shows the power in the lower 256 of the 512 channels (OVSFs or spread codes). The remaining 256 channels are shown in the lower left graph.
In Zoom View, the top-left graph shows all 512 channels (OVSFs or spread 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 (seeTable 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"
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
