9.7.7 Phase Frequency Menu
In this menu, the phase error of the signal transmitted by the mobile is displayed as a function of the
time. In addition the peak phase error, the RMS phase error and the frequency error are indicated by
their measured values.
The display is divided into several fields:
The upper field indicates the phase error graphically during the burst. The graphics are continuously
updated, i.e. a quasi-real-time measurement is available for adjustment purposes.
Below the graph the measurement results for the frequency error, the phase error peak and the RMS
phase error are indicated. The values given are those of the current burst as well as an average and the
maximum over a predefined number of bursts. The tolerances can be defined in the configuration menu
for this measurement. The average power of the current burst is also displayed.
