Description of command Sig. State
This command changes the slot configuration and the RF levels that the CMU uses in test mode
(default parameters). All levels are relative to the reference level queried via
[SENSe:]BSSignal:PDATa[:TCH]:MSLot:RLEVel ?
. 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 –90 dBm, the individual timeslot
levels can be set in the range –47 dB to +80 dB, corresponding to an absolute level of
–137 dBm to –10 dBm.
In the default setting, only slot 3 is enabled, the level is 0 dB. By default, slot no. 3 is also the main
timeslot; see
CONFigure:BSSignal:PDATa[:TCH]:MSLot:MTIMeslot
command on p. 6.217 .
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.
