Parameters
PredefExpx is one of the following predefined expressions: PPEAk|PRMS|FREQuency|LENGth|UTIMe|POWer|
TEMPlate|CORNer|FLATness.
Default is PPEAK.
Description
This command allows to set a user-specific sequence of RF TX tests on the 2201R. The sequence has to be started
with the appropriate commands of the MEASure subsystem (:MEAS:GSM:CONT:RFTX:GROU or
:MEAS:GSM:ARR:RFTX:GROU).
The meaning of the parameters is as follows:
PPEAk is the peak phase error measurement,
PRMS the root-mean square value of the phase error measurement.
FREQuency means the frequency error of the mobile under test,
LENGth 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 RF output power level of the mobile in dBm.
TEMPlate indicates whether the power/time template has been violated by a burst or not.
CORNER gives the RF power level in dBm at eight predefined positions of a burst.
FLATness gives an indication whether the RF output power of the mobile is constant during the useful part of the
burst.
Notes
This command must be used with at least one parameter specified. All other parameters are optional.
Unless organized in this sequence, the start of a new RF TX test always terminates the preceding one instantly.
Therefore, this command is an efficient way to perform several RF TX measurements in a sequence.
Query
The query form of this command returns the current sequence of RF TX tests to be performed by the 2201R. The
string delivered back contains a maximum of nine short-form versions of the predefined expressions explained
above.
