RREPorts
The subsystem
RREPorts
contains the commands for requesting the receiver report of the mobile.
Together with
NETWork[:MS]
the subsystem corresponds to the softkey
MS Rcv. Reports
in the main
menu
GSMxxx-MS Overview.
The receiver characteristics do not really represent a measured value,
since the values are automatically transmitted during signalling.
[SENSe:]RREPorts:RXLevel?
RX Level
Return
Description of parameters Def. value Def. unit FW vers.
0 to 63
Receiver level on mobile phone NAN – V1.15
Description of command Sig. State
This command is always a query. It outputs the receiver level that the mobile reports to the CMU,
expressed in levels without dimension (see chapter 4). CEST
[SENSe:]RREPorts:RXQuality?
RX Quality
Return
Description of parameters Def. value Def. unit FW vers.
0 to 7
Received signal quality on mobile NAN – V1.15
Description of command Sig. State
This command is always a query. It outputs the received signal quality that the mobile reports to the
CMU, expressed in quality levels without dimension (see chapter 4). CEST
