GSM frame clock. Use this simple synchronization method for
frames that start with a series of active slots and end with
inactive slots.
Pattern
The R&S CMW 500 searches for a definite burst pattern, defined
via "Acquisition > Pattern".The trigger events are generated at
the beginning of the pattern and repeated according to the
GSM frame clock, even though the true burst pattern may have
changed. Use this synchronization method for arbitrary multislot
configurations.
GPIB command: CONFigure:GSM:MEASurement<i>:MEValuation:AMODe
Acquisition > Gap Length
Number of consecutive inactive slots preceding the frame boundary (and therefore the
acquisition trigger event).
GPIB command: CONFigure:GSM:MEASurement<i>:MEValuation:GLENgth
Acquisition > Pattern
Burst pattern in the UL frame. Each of the 8 timeslots can be inactive ("Off") or carry a
GMSK-modulated or an EDGE burst.
GPIB command: CONFigure:GSM:MEASurement<i>:MEValuation:APATtern
8.2.1.5 GSM Multi Evaluation Configuration: Limits
The "Limits" in the "Multi Evaluation Configuration" dialog define upper limits for the
modulation and spectrum results. See also Conformance Requirements and Limit
Settings.
Multi evaluation configuration: Limit settings
The limits for GMSK and 8PSK-modulated (EDGE) bursts are defined separately.
