Parameter for code domain power measurements
TRACE1 | PWCDp | CWCDp | CTABle
Transmitted values for code domain power measurements
The transmitted values depend on the parameter selection.
Value Description Range Unit
<code class> code class of the channel
–1 indicates that the channel does not have a code class
(e.g. for PSCH)
{–1, 2 ... 9}
<class> spreading factor of the channel
code class 9 corresponds to the highest spreading factor
(512, symbol rate 7.5 ksps), code class 2 to the lowest
admissible spreading factor (4, symbol rate 960 ksps)
–1 indicates that the channel does not have a valid
spreading factor (e.g. for PSCH)
<channel number> code number of the channel
–1 indicates that the channel does not have a regular
channel number (e.g. for PSCH)
<absolute level> absolute level of the code channel at the selected channel
slot

<relative level> relative level of the code channel at the selected channel
slot referenced to CPICH or total power

dB
<timing offset> timing offset of the code channel to the frame start
step width is 256 chips for code class 2 to 8,
512 chips for code class 9
{0 ... 38400} chips
<pilot length> pilot length of the code channel
According to the 3GPP standard, the pilot length range
depends on the code class.
