:MEASure:GPRS:ARRay:RFTX:ALL
Syntax
:MEASure:GPRS:ARRay:RFTX:ALL <int1>
Parameters
int1 is an integer.
The minimum value for int1 is 0, the maximum value is 100. The default value for int1 is 0.
Description
Measures multiple times (set with the int1 parameter) all RF TX parameters. To read out the entire measurement
results array, use the :FETCh:GPRS: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 returns a string, containing int1 times 19 measured values separated with commas.
The order and type of the measurement results delivered back are as follows:
1. PPEAk, floating point real number,
2. PRMS, floating point real number,
3. FREQuency, floating point real number,
4. LENGth, floating point real number,
5. UTIMe, floating point real number,
6. POWer, floating point real number,
7. TEMPlate, a boolean number,
8...15. CORNer, eight floating point real numbers,
16...19. FLATness, four floating point real numbers.
The items 1... 19 are repeated in the same order and format int1 times for all measurements.
Example
:MEAS:GPRS:ARR:RFTX:ALL 2
:FETCH:GPRS:RFTX:ALL?
In this example, the sequence of the RX TX measurements is performed twice. All 38 measured values are kept in an
internal memory until they are read out with the :FETCh command. After the internal memory has been read out, it
is cleared.
Note: Consequently, a subsequent :FETCh command (without any previous start of a measurement) tries to read
non-existent measurement data and result in a timeout error.
