Signalling: POWer:PCL CMU-K20/21/22/23/24
1115.6088.12 6.144 E-12
Description of command
This command defines the GSM channel numbers for the P/PCL measurement. The total number n of channels
measured is either 3 or 7, depending on the
CONFigure:POWer:PCL:CCOunt
setting.
If 7 channels are measured, the following default values apply:
GSM400 259, 265, 270, 276, 282, 287, 293
GSM850 128, 149, 169, 190, 210, 230, 251
GSM900 1, 22, 42, 63, 83, 104, 124
GSM1800 512, 574, 636, 669, 761, 823, 885
GSM1900 512, 562, 611, 661, 711, 760, 810
Subsystem POWer:PCL
The subsystem POWer:PCL contains the commands for measurement and output of the power versus
PCL application for three or seven selected channels. The subsystem corresponds to the measurement
menu
P/PCL.

Description of command
These commands are always queries. They start a measurement and return all measurement results. The
returned list contains all possible PCLs of the mobile phone together with the measured MS output powers in the
three selected channels. The output values are:
- PCL1 to PCLn PCLs of the mobile
- PxChy Average burst power for PCL = x and channel = y
The PCL range depends on the GSM phase and the power class of the mobile. For a list of possible PCLs and
nominal maximum output power of the mobiles refer to chapter 4.
