CTS55 List of Commands/Annex C
1094.0006.55 C.39 E-8
1.8 Remarks
1.8.1 (N1)
-) The transmitter power is adapted, if necessary (see also (N3)).
-) The input may be overdriven if an external amplifier is connected.
-) The settings have only influence on the <default mobile>. It should be selected previously.
1.8.2 (N2)
During signalling, RXLEV, RXQUAL and POWER LEVEL are automatically polled by the mobile at
regular intervals and thus updated.
The measurement for SENSe:POWer:MS? also runs automatically as soon as the connection is set up.
1.8.3 (N3)
-) The value is valid irrespective of the output and is automatically adapted to the output on transition to
the MIDL state, which may cause the value range to be shifted.
-) The value applies to the currently set timeslot of the TCH.
-) For the value range see Manual Operation, section 2.
1.8.4 (N4)
Using a READ command, a new measurement is started and the desired value(s) returned. The result
of this measurement can be repeatedly read by using a FETCh query without performing a new
measurement. The FETCh command should only be used after a read has been executed otherwise
initialisation values will be returned.
1.8.5 (N5)
After calling of a READ command, all scalar measurement results (average power, RMS and peak
phase error and frequency error) are calculated and the desired value is returned; the remaining
measurement results can be fetched using FETCh or CALCulate. However, if the measurement is
made via READ:ARRay, the scalar values are available in addition to the selected field values. The
measurement of the field values of the power (READ:ARRay:BURSt:POWer?) and phase error
(READ:ARRay:BURSt:PHASe:ERRor?) are mutually exclusive, i.e. after READ:ARRay:BURSt:POWer?
it is
not possible to fetch the phase errors by means of FETCh:ARRay:BURSt:PHASe:ERRor?. The
timing is measured when the power field values are measured, but not when the phase error is
measured.
1.8.6 (N6)
The results of the tolerance query have the following meaning:
MATC: The measurement result observes the configured limit values
NMAT: The measurement result does not observe the configured limit values
INV: No measurement result is available
1.8.7 (N7)
If a READ measurement command cannot be performed, the CTS will return NAN (Not A Number), to
indicate a non-valid result. A FETCh command will also return NAN either after a non-valid
measurement or if no measurement has been performed previously.
