Note: If the nanoBTS has not been powered up for 24 hours, a warning message
will be displayed. The warning messages re-iterate the importance of waiting
24 hours before performing the final calibration. To continue with the
calibration, click OK to display the Frequency Control dialog.
Note: The frequency of a nanoBTS can only be adjusted manually if Internal
OCXO is the active clock source. If the Internal OCXO is not the active clock
source and the nanoBTS being adjusted is a master, remove its 10 MHz
input.
4. If required, click Enabled in the TIB Output section.
5. Use the Frequency Control spin buttons to adjust the internal OCXO frequency
while observing the effects in real-time using the external measuring equipment.
The frequency can be adjusted in steps of x1, x10 or x100.
Note: The ideal tolerance range for Freq Qual is 50...63, for Freq Error -50...0...50.
6. When the nanoBTS is set to the required frequency (26 MHz for nanoBTS models
that are not multi-TRX capable, 1.625 MHz for nanoBTS models that are multi-
TRX capable) and within the required tolerance, stop.
7. Click Close. If any settings have been changed in the Frequency Control dialog, a
warning message is displayed that enables these settings to be returned to their
earlier values.
