Modulation Measurements

MS278XB OM

5-59

Below is the Summary table showing the key modulation quality measurements and the bit stream for
one of the codes. In this case, it is code #11 at spreading factor 128. The modulation quality
measurements are again very similar to the Composite & QPSK measurements with minor differences.
For example, PCDE and Rho don’t make sense for a single code.
Note that the bit stream can be very long in some cases. If you have captured the full 8 frames and have
a high speed (HSDPA) signal, there can be many pages of the bit stream. The scroll buttons at the right
facilitate viewing all of this information.
