BER Test Setups
The
BER
table section
defines up to 10 user-specific configuration files for single
shot
Receiver Quality
measurements (application
BER).
The test setups are
numbered from 1 to 10 and can be called up via the
Test Setup
hotkey associated
to the
BER
softkey. They differ from each other in the default settings for the signal
power of the CMU and the criteria for analysis.
Remote control
The application number is denoted by a numeric suffix in the RXQuality commands
(...RXQuality:BER<nr>:...).
Test Name
The
Test Name
option assigns a name to each of the 10 test setups. In the
Test
Setup
hotkey, the individual test setups are referenced with their
Test Names
.
Remote control
A numeric suffix in the RXQuality commands
(...RXQuality:BER<nr>:...)
denotes the application number
.
Stop Condition
The
Stop Condition
parameter defines a stop condition for the measurement:
NONE
Continue measurement even in case of error
1
st
Limit exceeded
Stop measurement on first error (tolerance exceeded)
All Limits exceeded
Stop measurement if all tolerances are exceeded
Confidence Level
Stop measurement as soon as the BER confidence level
exceeds the values set in the
Confidence Settings
section
described on p.
4.138
.

Frames
The parameter
Frames
defines the statistic count (= the number of speech or data
frames to be sent in a
BER
measurement). A low value permits to limit the scope
and accelerate the measurement.
The meaning of a frame and its bit content depends on the service, the frame type
and the channel coding; see section
Frame Structure for Speech and Data
Channels
