Description of command Sig. State
This command defines the active timeslots slots of the BS signal (default values) and the levels for
the
Individual
level mode (see command
CONFigure:BSSignal[:CSWitched][:TCH]:MSLot:LMODe
on p. 6.190 ). All 8 timeslots can be enabled and their levels can be set individually. They are defined
relative to the
Reference Level
set via
CONFigure:BSSignal[:CSWitched][:TCH]:MSLot:RLEVel
(see
p. 6.189 ). The level range quoted above is restricted by the condition that the absolute level
(calculated from the reference level and the relative individual levels) must not exceed the level
ranges of the RF connectors.
Example:
With output connector RF2 and a reference level of –85 dBm, the individual timeslot
levels can be set in the range –52 dB to +75 dB, corresponding to an absolute level of
–137 dBm to –10 dBm.
In the default setting, slots 3 and 4 are enabled, both levels are 0 dB. By default, slot no. 3 is also the
main timeslot; see
CONFigure:BSSignal[:CSWitched][:TCH]:MSLot:MTIMeslot
command on p.
6.190 .
Note 1: The <Enable_n> parameters also apply in used/unused level mode; they overwrite the
parameters in the
CONFigure:BSSignal[:CSWitched][:TCH]:MSLot:SCONfig:UUNused
command.
Note 2: Reserved BCCH Slot
If the control channel mode is set to BATC (see command
CONFigure:BSSignal:CCH[:TX]:MODE
on p. 6.186 ),
slots 2 to 6 can be configured as
traffic channels. The settings for slots 0, 1 and 7 are ignored; a query returns BCCH for
slot no. 0.
