Initial Frequency Calibration
NOTE:
The FlexWave™ nano must be powered on for a minimum of 24 hours prior
to final frequency calibration. It is recommended that during installation an initial,
local calibration is made following a powered on time of > 10 minutes followed by a
final operational calibration after 24 hours power on time.
NOTE:
If the FlexWave™ nano is used in a Multi-TRX configuration, then the TIB
OUT must be disconnected from each FlexWave™ nano in the chain prior to
calibration and reconnected afterwards. Only the Master TRX should be calibrated.
•
Using BTSInstaller, select the FlexWave™ nano that is to be calibrated and
then click on the “Listen” button in the “BTS Status” pane.
•
Select the frequency band to match that of the FlexWave™ nano to be
installed.
•
Click on the “Connect” button, this will cause the FlexWave™ nano TRX to
power up. The status LED will flash green when completed.
•
Click on the “Channel Usage” tab and then click on the “Start Test” button.

When completed click on the “BCCH Channel Usage” tab and then click on the
“Start Test” button.

•
Select the “Freq Sync Options” tab and then click on the “Apply Frequency
Synch Options” and change the Option to “Adjust The Clock To Correct The

Once the test completes then the calibration is completed and the procedure should
be repeated for all installed FlexWave™ nano before reconnecting the TIB cables.
Following the 24-hour period, the Frequency Calibration procedure should be
