Code Order (cdma2000/1xEV-DV)

Code Order sets the Code Domain Power display code order to Bit Reversed or Hadamard. This will determine how the code domain power trace data is displayed.

Bit Reversed: Reorders related code channels (Walsh Code Number) so that they are viewed adjacent to each other on the code domain power trace data display,
Hadamard (Default): Related code channels (Walsh Code Number) are viewed as dispersed along the X-axis as defined by the Hadamard code order on the code domain power trace data display,

Code Order effects how the Code Domain Power data is displayed and does not change the measurement results.

Using Code Order to make cdma2000 Code Domain Power measurements

For cdma2000/1xEV-DV modulation, the code domain power display shows related code channels (Walsh Code Number) dispersed along the X-axis as defined by the Hadamard code order. This makes visually identifying the related code channels difficult.

Another way to look at the same data is by reordering the code channels so related code channels are displayed adjacent to each other. The Bit-Reversed generation of Walsh channels provides us with the desired code number assignment.

To view related code channels (Walsh Code Number) grouped together for cdma2000/1xEV-DV modulated signals select the Bit-Reversed Code Order.
