Measurement Results
The results displayed in the
Analyzer/Generator
menu depend on the selected application:
The results for the
P/t Norm. GMSK
and
Ext. Phase Error
GMSK
applications are displayed simultaneously because
both applications can be run in parallel. The results
appear in two output fields, each containing three entries.
A header line indicates the name of the application and its
measurement status. The current application is
underscored.
All results refer to the current burst. No comparison is
made between different bursts, so the result does not
depend on the statistical settings (e.g. single shot or
continuous measurement).
P/t Norm. GMSK
The
P/t Norm. GMSK
output field indicates the average and peak burst power as
well as the result of the limit check:
Avg. Burst Power (Current)
Average power of the current burst in dBm.
Peak Burst Power (Current)
Peak power of the current burst in dBm.
Power Ramp
Matching of the tolerances by the current burst. The
messages that may appear in the list field are self-
explanatory.
The
P/t Norm. GMSK
results are also indicated in the info box in the graphical
measurement menu
Power
(see section
P/t Normal GMSK

4.20

Ext. Phase Error
GMSK
The
Ext. Phase Error GMSK
output field indicates the average (RMS) and peak
phase error and the frequency error:
Frequency Error
Frequency error of the current burst
in Hz.
Peak Phase Error (Current)
Extreme value of the phase error (minimum or
maximum, whichever has the larger absolute value) of
the current burst in degrees. The result can be positive
or negative.
RMS Phase Error (Current)
RMS phase error of the current burst in degrees.
The
Ext. Phase Err. GMSK
results are also indicated in the graphical measurement
menu
Modulation
(see section
Measurement Results
on p.
4.41
ff.). For a detailed
explanation of the quantities characterizing the GMSK modulation accuracy see
