Chapter 4 - Operation
In an RB, only if the RB is associated

If the calibration has started the unit will reset itself, will perform the calibration
and after that it will reset again and return to normal mode of operation.
The calibration process may take several minutes: 6 seconds for each of the
channels available in the tested sub-band, plus two resets.
If the calibration is running the user will not be able to start a spectrum analysis
or a TFTP/FTP session.
If the calibration failed the results of the previous successful calibration will be
kept. If the calibration passed, the new results will be used for Noise Floor
Indication.
4.2.6.2.17.2 Select Calibration Option to Use
This option enables selection of the calibration option to be used by the device.
The available options are None, Field and Factory.
If Factory option is available, indicating that the unit was calibrated in the factory
(in the current version Factory calibration is not available), this is the option that
should be used.
If Factory option is not available, a Field calibration should be performed (using
the Run Calibration option), and the Field option should be selected.
The None option should be used only if the Field Calibration is repeatedly failing
(see Show Noise Floor Calibration below), or if the RSSI displayed when using the
Field option (following a "successful" Field calibration) is clearly inaccurate,
indicating erroneous results.
The default is None.
4.2.6.2.17.3 Show Noise Floor Calibration
Select this option to view the current status and parameters of Calibration of
Noise Floor Indication. The displayed parameters are:
Field Calibration Status: Indicating the result of the last Field calibration

process (Passed, Failed or None if no Field calibration has been done).
Last Field Calibration Result: Indicating the result of the last Field

Calibration process (Success or Failed).
Bandwidth Used for Last Field Calibration: The bandwidth used by the

device during the last Field Calibration. A new Field Calibration should be
performed after changing the bandwidth (sub-band) used by the device.
