Description of command Sig. State
This command determines the level of the control channel in absolute units.
Note: In firmware versions <V3.10 the BCCH level can not be changed in the CEST state.
After a handover the BCCH level of the origin network is maintained (indication
"from other network" in the BS Signal tab of the Connection Control menu),
however, the query
CONFigure:BSSignal:CCH[:TX]:LEVel[:ABSolute]?
will return the default value of the target network, which may differ from the actual
BCCH level.
Changing the BCCH level after a handover (i.e. in the CEST state of the target
network) is not allowed and will cause an error message –200, "Execution error".
