Single Code Measurement

The next class of modulation quality measurements focuses on a single WCDMA code. This is again very similar to the QPSK and Composite measurement selections, but with a few significant differences. Instead of an optional summary table with each measurement, there is an optional Code Domain Power graph; this helps the user visualize which code is being measured. The summary table is still available, but in this case it is a separate display (rather than an option to the other displays). One other difference is the Power vs. Time display; in this case, instead of focusing on the detail of 1 slot, the display shows the power level over a longer time frame—up to 8 frames (120 slots) total.
