9.7.9 BER Sensitivity measurement
This measurement is able to measure a mobile’s receive sensitivity which is defined as the lowest "BS
Signal" that allows the BER measurement results to be just within the configured tolerances.
This measurement can be started from the "Call Established" menu by activation of the BER
measurement. Either the "BER Sensitivity" menu is entered directly or it can be activated by pressing the
softkey labelled "BER Sens." in the "Ber Continuous" menu.
On entering the "BER Sensitivity" menu the measurement will be started automatically. The "BS Signal"
will be ramped down from a configured initial value until the sensitivity level is reached and then the
resulting "BS Signal" value is displayed in the "BER Sens." result field. The measurement can be made
again by pressing the "Restart" softkey. A measurement can be stopped while in process by pressing
the "Stop" softkey and then restarted by pressing the "Cont" softkey.
The "BER Sensitivity" configuration menu is accessible via the main configuration menu as well as via
the measurement menu itself.
The following value is indicated at the display:
BER Sens.
The speech channel level (TCH level), where the defined BER is reached.
Restart

BER Cont.
To change to continuously BER measurement.
