parameter, the calculated value will be used. Otherwise, the Forced Value will
be used.
The default option is Fully Automatic.
4.2.6.2.15.2 Forced Value
The Forced Value parameter enables configuring the Noise Floor to be used if the
selected Calculation Mode is Forced. This is also the minimum value to be used if
the selected Calculation Mode is Automatic with Minimum Value.
If you decided to change the calculation mode to Automatic with Minimum Value
and you still experience problems in the link (long association time, exceptionally
low throughput), try to improve it by increasing the configured Forced Value.
The available range is from -107 to -55 (dBm)
The default value is -96 (dBm)
4.2.6.2.15.3 Show Noise Floor Calculation
Select this option to view the current values of the Noise Floor Calculation
parameters and the Noise Floor Current Value (the actual current value used by
the device).
4.2.6.2.16 Calibration of Noise Floor Indication
The Calibration of Noise Floor Indication feature has been introduced to overcome
possible inaccuracies in the Noise Floor Calculation mechanism. The calibrated
Noise Floor Indication is used for correcting the displayed Noise Floor values
versus the values that are calculated/used by the internal noise floor calculation
mechanism.
The Calibration of Noise Floor Indication submenu includes the following options:
4.2.6.2.16.1 Run Calibration
Select the Run Calibration option to perform a new calibration process. Typically
this should be performed for a new unit when Factory calibration is not available,
whenever the bandwidth (sub-band) is being changed (not applicable for current
release), or if the previous calibration process has failed.
Calibration can be performed only under the following conditions:
The Spectrum Analyzer is not in progress

There is no active TFTP or FTP session

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.
