Technical data

the Transmit option, the network operator will be able to select
these values for BERT test:
• The Output Power Level for transmitter: defined through the
dedicated control in the range from 13 to 33 dBm (to set the
required values, the LINK PWRB command must be used)
• Interval – defines in ms the interval in which the frames will
be transmitted. The Interval range is 125 to 1000 ms.
• The modulation type of transmitter – DBPSK, DQPSK, D8PSK,
D16QAM
In Transmit state, AWare first sets the outputted power level and
then periodically sends the test sequences in predefined intervals. By
receiving that sequence, the unit starts transmitting the received
frames to the receiver.
Figure 6-2: BERT Transmit Dialog Box
In Receive state, AWare BERT dialog box shows the received and
lost frames counters, total received bits, user data, rate of BER and
FLR (Frame Loss Rate). The BERT dialog also indicates the power
level of transmitter (TSTUFR REMOTEPWR command will be used),
the RSSI/RSL on receiver (it will be obtained through Statistics In-
terface), and Recommended Output Power Level for transmitter
which is calculated based on the transmitter’s power level, receiver’s
RSSI/RSL level, BER and frame loss rate tolerance on receive site.
