The normal process for manual frequency adjustment is for the user to:
• connect external frequency measuring equipment to the nanoBTS TIB out port
using the correct type of cable
• use the Frequency Control command to change the Frequency Control
attribute whilst observing the effects using the external measuring equipment
• stop when the nanoBTS is set to the required frequency (26MHz for nanoBTS
models that are not multi-TRX capable, 1.625 MHz for nanoBTS models that
are multi-TRX capable) within the required tolerance.
Selection, connection, calibration and use of external frequency measuring equipment
is beyond the scope of this User Guide. The external Frequency Counter should,
however, be referenced to an accurate and stable source such as a Rubidium or GPS
reference.
PRIOR TO CALIBRATION THE nanoBTS SHOULD BE POWERED UP
FOR A MINIMUM OF 10 MINUTES TO ALLOW IT TO STABILISE
When the Frequency Control button is clicked, BTS Installer first checks the unit’s Up
Time.
If the unit’s Up Time cannot be determined (for example if the BTS is running pre-
SR2.0 software), BTS Installer displays a warning message, “The nanoBTS’s Up Time
could not be determined. The nanoBTS’s internal oscillator may not have settled
sufficiently for frequency adjustment to be sufficiently accurate. It is recommended that
frequency adjustment be carried out only after the nanoBTS has been running for at
least 24 hours. Do you wish to continue?” with an OK button and a Cancel button.
If the unit’s Up Time is less than 10 minutes, BTS Installer displays a warning
message, “Up Time is less than 10 minutes. The nanoBTS’s internal oscillator is very
unlikely to have settled sufficiently for frequency adjustment to be sufficiently accurate.
It is recommended that frequency adjustment be carried out only after the nanoBTS
has been running for at least 24 hours. Do you wish to continue?” with an OK button
and a Cancel button.
If the unit’s Up Time is equal to or greater than 10 minutes but less than 24 hours, BTS
Installer displays a warning message, “Up Time is less than 24 hours. The nanoBTS’s
internal oscillator may not have settled sufficiently for frequency adjustment to be
sufficiently accurate. It is recommended that frequency adjustment be carried out only
after the nanoBTS has been running for at least 24 hours. Do you wish to continue?”
with an OK button and a Cancel button.
