Description of command
If used as a setting command with the parameter
ON

default values (the setting
OFF
causes an error message).
If used as a query the command returns whether all parameters are set to their default values
(ON)
or not
(OFF)

Subsystem MSSignal (Signal of Mobile Station)
The subsystem
MSSignal
configures the operating mode and the RF traffic channel signal of the MS
under test. It corresponds to the tab

Description of command Sig. State
This command defines the maximum MS transmitter output power allowed in the cell. The value
corresponds to the output power at which the mobile station synchronizes to the network. It is valid
both for circuit-switched and for packet data mode. An overview of power control levels (PCL) in GSM
is given in chapter 4 (see table or index).

Q: all
The output power during a call can be set by means of the following commands:
CONFigure:MSSignal[:CSWitched][:TCH][:SSLot]:MS:PCL
(circuit switched, single slot)
CONFigure:MSSignal[:CSWitched][:TCH]:MSLot:SCONfig
(circuit switched, multislot)
CONFigure:MSSignal:PDATa[:TCH]:MSLot:SCONfig
(packet data, single slot)

Description of command Sig. State
This command permits the mobile to make use of the DTX mode
(discontinuous transmission mode)
.
The status assumed by the mobile is to be determined using the command
[SENSe:]RREPorts:DTX?
.
Only useful data are transferred in DTX mode; if nothing is spoken, the mobile will transmit nothing in
the traffic frames.

Q: all
1 In firmware versions <V3.05, this command is replaced by
CONFigure:NETWork[:MS]POWer
. This command sets the maximum MS transmitter power and the MS
transmitter power during a call to the same value. It is still available for compatibility reasons.
