Receiver Reports and Power Measurements
Besides the signalling parameters discussed above the receiver reports of the mobile station are
transmitted to the CMU. Power and modulation measurements can be performed as in the
Non Signal-
ling mode.
Step 1
The Overview menu indicates the most
important settings in the function group
GSM900-MS Signalling and the main re-
sults of the Power and Modulation meas-
urements (output fields Ext. Phase Err.
GMSK). Moreover the receiver reports of
the mobile station are displayed.
"
Power and Modulation measurements can
be performed in close analogy to the
measurement of GSM signals in the
Non
Signalling mode. The differences between
the two modes are related to the settings
which can be made at the mobile station.
