6.4.1 BER Sensitivity measurement
BER Sensitivity Menu
Config BER Sensitivity Menu
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 measure-
ment 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" configu-
ration menu is accessible via the
main configuration menu as well
as via the measurement menu
itself.
