:MEASure:GPRS[:CONTinuous]:MULTislot:RFTX:ALL
Syntax
:MEASure:GPRS[:CONTinuous]:MULTislot:RFTX:ALL
Parameters
There are no parameters.
Description
Measures repetitively all RF TX parameters for the number of time slots set by the :CONFigure:GPRS:MSTAtion:MSLot
command. The number of time slots measured is the first parameter in the result string. To read out the latest
measurement results, use the :FETCh:GPRS:MULTislot:RFTX:ALL command.
The RF TX tests performed by this command are:
PPEAk, the peak phase error measurement,
PRMS, the root-mean square valued phase error measurement,
FREQuency means the frequency error of the mobile under test,
LENGth is the length of the burst in microseconds,
UTIMe stands for the timing error of the mobile under test in microseconds (taking the ordered timing advance into
account),
POWer is the mobile RF output power level in dBm,
TEMPlate indicates by returning 1 and 0 that the power/time template has and has not been violated by a burst
respectively,
CORNer gives the RF power level in dBm at eight predefined positions of a burst,
FLATness indicates whether the mobile RF output power is constant during the active part of the burst.
Notes:
Please keep in mind that the start of a new RF TX test always terminates the preceding one instantly.
For more information on the single measurements, see description of the related commands below.
Query
The query form of this command starts the measurements and - after all measurements have been completed and
all measurement results have been obtained for all time slots - delivers a string, containing an integer number
indicating the number of time slots measured followed by 19 measured values for each time slot, separated with
commas. The order and type of the measurement results delivered back are as follows:
1. The number of time slots measured, an integer number,
2. PPEAk, floating point real number,
3. PRMS, floating point real number,
4. FREQuency, floating point real number,
5. LENGth, floating point real number,
6. UTIMe, floating point real number,
7. POWer, floating point real number,
8. TEMPlate, a boolean number,
9...16. CORNer, eight floating point real numbers,
17...20. FLATness, four floating point real numbers.
The items 2... 20 are repeated in the same order and format for each time slot measured.
Example
:MEAS:GPRS:CONT:MULT:RFTX:ALL?
For the number of measured time slots set to 1, 19 relevant RF TX measurements are performed in a sequence. As
soon as all measurements have been completed and all measurement results obtained, a string is delivered back
containing the number of time slots measured and the measurement results. Example:
"1,5.13,1.94,-2.22,557.0,0.1,11.22,0,-72.18, -61.91,-20.91,-0.05,-0.04,-17.97,-56.60, -73.95,-0.05,-0.01,0.02,-0.05".
