Key Sequence:
Measurements > Demodulator
CDP MAC: The first press of this submenu key begins a CDP MAC
measurement and also displays an arrow on the soft key (to indicate that a
sub menu is available). The Code Domain Power (CDP) MAC view
displays all of the Pilot and MAC codes in a color coded graphical format.
MAC channels are Walsh despread into 64 sub-channels (physical layer
Subtype 0 or Subtype 1) or 128 sub-channels (physical layer Subtype 2).
The bottom half of the CDP graph area shows a zoomed-in view of the
code powers. A blue mask behind the zoomed-in area is duplicated in the
upper graph to indicate which signals are in the zoom view.
The numerical results displayed in this view are:
Pilot and MAC Power (dBm)
Freq Error (Hz)
Rho Pilot
Data Modulation
Channel Power (dBm)
Freq Error PPM
Rho Overall1
Noise Floor (dB)
The codes are color coded according to the following list:
Reserved Channels in White
Inactive channels in Gray
Reverse Activity (RA) in Red
Active channels alternate between Orange and Yellow
An additional press of the CDP submenu key opens the “CDP MAC Menu”
on page 3-30 .
CDP Data: Lists the CDP Data menu. The Code Domain Power (CDP)
Data view displays only the data code powers. The display is split into the
I (In phase) data and Q (Quadrature phase) data components. Each
contains 16 sub-channels.
The numerical results that are displayed in this view are:
Active Data Power (dBm)
Rho Pilot
Max Data CDP
Data Modulation Type
Rho Overall1
Min Data CDP
