Channel Table
With the TRACE1 | TRACE2 parameter, the following values are transferred for each channel: <channel
type>, <code class>, <code number>, <radio configuration>, <absolute level>, <relative level>, <timing
offset>, <phase offset>, ...
Parameter Description Output value
channel type channel type , coded with numbers 0 – PICH
1 – SYNC
2 – PCH
3 – TDPICH
4 – APICH
5 – ATDPICH
6 – BCH
7 – CPCCH
8 – CACH
9 – CCCH
10 – CHAN
11 – INACTIVE
12 – PDCCH

code class code class of the channel, specifies the
spreading factor
2 to 7
2 corresponds to the lowest allowed spreading factor
(4, symbol rate 307.2 ksps)
7 corresponds to the highest spreading factor (128,
symbol rate 9.6 ksps)
code number code number of the channel 0 to 127
