The initial paging channel is set to Walsh code 1.
This step scales the power levels of the active channel so
that they display the correct power levels being transmitted.
The ratios are kept the same. If your total power is equal to

After configuring the hardware, follow the steps in Table 2 below to configure the instrument appropriately. In this
example, Pilot, Sync, Traffic, and Paging channels are defined. For IS-95, the traffic channel may be defined as RC1
or RC2. This example is intended to illustrate a basic set-up from which the user can customize the instrument to
meet his needs. Values in brackets [ ] are for example purposes only and the actual value should be determined by
the user. Hard key selections are indicated by bold text.
