READ[:SCALar]:POWer:SLOT:SPOWer<nr>? Single Result
Start single shot measurement and return results
FETCh[:SCALar]:POWer:SLOT:SPOWer<nr>? Read out measurement results (unsynchronized)
SAMPle[:SCALar]:POWer:SLOT:SPOWer<nr>?
Read out measurement results (synchronized)
Returned Values Description of parameters Def. value Def. unit FW vers.
–100 dBm to 100 dBm Avg. power in slot <nr> NAN dBm V2.15
Description of command
These commands are always queries. They start a measurement and return the average power in a particular
timeslot (numbered by <nr>=1 to 8, corresponding to timeslots 0 to 7).

Description of command
These commands are always queries. They start a measurement and return all measurement results. The
returned list contains the average burst power of the mobile phone in eight consecutive timeslots.

dB V2.15
Description of command
These commands are always queries. They return the burst power versus time in a fixed ¼- bit pattern and in the
subranges defined by means of the
CONFigure:SUBarrays:POWer[:NORMal][:GMSK]:MPR
command. In
the default setting of the configuration command the
READ:SUBarrays..., FETCh:SUBarrays..., and
SAMPle:SUBarrays...
command group is equivalent to the
READ:ARRay..., FETCh:ARRay..., and
SAMPle:ARRay...
command group described above.
The
CONFigure:SUBarrays:POWer[:NORMal][:GMSK]:MPR
command defines a maximum of 32
subranges. If one of the statistical modes
(ARIThmetical, MINimum, MAXimum)
is set, only one value is
returned per subrange.
The calculation of current, average, minimum, and maximum results is explained in chapter 3 (cf. display mode ).
