BreezeNET B 127 System Manual
The range is from 0 to 4. In the current version only 0 and 4 should be used.
The default is 0.
4.2.6.2.15.3 Spur Immunity Level
The Spur Immunity Level parameter sets the threshold for immunity against
narrow band interfering signals such as spurious from signals at other
frequencies. A higher value may reduce the number of errors at the expense of
reduced sensitivity.
The range is from 0 to 7.
The default is 0.
4.2.6.2.15.4 OFDM Weak Signal
The OFDM Week Signal parameter sets the threshold for immunity against
interfering OFDM signals.
The available options are 0 or 1. A value of 1 means that the unit will immediately
reject OFDM packets with a relatively low SNR.
The default is 0.
4.2.6.2.15.5 Pulse Detection Sensitivity
The Pulse Detection Sensitivity parameter affects the Phy error count: If it is set to
Low, than all Phy errors will be reported as regular Phy errors, regardless of the
signal level. If it is set to High, all Phy errors with levels bellow a certain threshold
(not accessible to the user) will be reported as regular Phy errors, while those with
levels higher than the threshold will be reported as detected radar pulses.
When DFS (radar detection) is used or during a Spectrum Analysis test, the Pulse
Detection Sensitivity is set internally to High (regardless of the configured value).
The default is Low.
4.2.6.2.15.6 Show Noise Immunity
Select this option to view the current values of the Noise Immunity Control
parameters, and some additional parameters of the ANI mechanism.
4.2.6.2.16 Noise Floor Calculation Parameters
The Noise Floor calculation mechanism incorporated in the units is used for
estimating the level of the noise floor. This value is used for estimating SNR values
and for decisions on existence of signals in the channel. In some cases, especially
when a very strong signal exists in neighboring channels, the noise floor
calculated by the built-in mechanism may be significantly below the actual noise
floor level.
Typically, the expected noise floor level is:
