R&S FSL TRACe Subsystem (CDMA, K82)
1300.2519.12 6.625 E-11
Code Domain Power
The following values are transferred for each channel: <code class>, <code number>, <signal level>,
<power ID>, ...
Parameter Description Output value
code class code class of the channel, depending on the order
setting via the [SENSe<1|2>:]CDPower:ORDer
command
Hadamard order: corresponds to the class that
belongs to the base spreading factor
BitReverse order: 2 to 7
code number code number of the channel 0 to 127
signal level absolute or relative power, depending on the
reference setting via the
[SENSe<1|2>:]CDPower:PREFerence
command
Hadamard order: power values of the different
codes
BitReverse order: consolidated channel power
(see [SENSe<1|2>:]CDPower:ORDer
command)
power ID power detection
To avoid alias power set the base spreading factor
correctly (see [SENSe<1|2>:]CDPower:SFACtor
command).
0 – inactive channel
1 – power of own antenna
2 – alias power of own antenna
3 – alias power of other antenna
4 – alias power of own and other antenna
For sorting the channels and consolidation, the order is important (refer to the
[SENSe<1|2>:]CDPower:ORDer command):
• In Hadamard order, the different codes are output in ascending order together with their code
power. The number of output codes corresponds to the base spreading factor.
• In BitReverse order, codes belonging to a channel are next to one another and are therefore output
in the class of the channel together with the consolidated channel power. The maximum number of
output codes or channels cannot be higher than the base spreading factor, but decreases with
every concentrated channel.
Example
The example shows the results of the query for five channels having the following configuration:
channel type channel spreading code code class signal level
PICH 0.64 6 –7.0 dB
PCH 1.64 6 –7.3 dB
CHAN 8.32 5 –8.0 dB
CHAN 24.128 7 –9.0 dB (alias with 24.64)
SYNC 32.64 6 –13.3 dB
INST:SEL BC2K
Activates the CDMA2000 BTS Analyzer option.
INIT:CONT OFF
Selects single sweep.
CDP:ORD HAD
Sets order to Hadamard.
INIT;*WAI
Starts measurement with synchronization.
