Description of command
This command changes the main timeslot, the levels in all active or inactive timeslots slots of the BS signal and
the channel-specific power control parameters
Γ
CH
that the MS uses in test mode (current values, see
Slot
Configuration Editor
in manual control). This command overwrites the main timeslot defined via
CONFigure:BSSignal:PDATa[:TCH]:MSLot:MTIMeslot
(see p. 6.217) .
For the DL signal all GSM timeslots are available if the control channel mode is set to BOTC (see command
CONFigure:BSSignal:CCH[:TX]:MODE
on p. 6.186 ). Their levels are set individually relative to the
Reference
Level
set via
[SENSe:]BSSignal:PDATa[:TCH]:MSLot:RLEVel
(see p. 6.217 ). The DL 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 DL timeslot levels can
be set in the range –52 dB to +75 dB, corresponding to an absolute level of –137 dBm to –10 dBm.
The UL signal settings must be compatible with the capabilities of the MS under test (multislot class, power
class).
