4.2.6.2.13.7 Spectrum Analysis Information Display - Continuous
The Spectrum Analysis Information Display - Continuous option is available only
when the analysis process is active. It enables viewing the continuously updated
results of the current analysis process. The displayed information includes the
same details available for a regular Spectrum Analysis Information Display
option.
4.2.6.2.13.8 Show Spectrum analysis Parameters & Data
The Show Spectrum analysis Parameters & Data option enables viewing the
Spectrum analysis test parameters and the last test results.
4.2.6.2.14 Lost Beacons Transmission Watchdog Threshold (BU only)
When it is unable to send beacon frames for a predetermined period of time, such
as in the case of interferences, the BU resets itself. The Lost Beacons
Transmission Threshold parameter represents the number of consecutive lost
beacons after which the unit will reset itself.
The range for this parameter is 100 - 1000, its default value being 218. When the
parameter is set to 0, this feature is disabled, i.e. internal refresh will never be
performed.
4.2.6.2.15 Noise Immunity Control
Noise Immunity Control parameters are available only in units with HW Revision
C and higher, except to the Pulse Detection Sensitivity parameter that is available
also in units with HW Revision B.
The Adaptive Noise Immunity (ANI) mechanism is designed to reduce the wireless
physical layer errors and by that enhance the processing power of the unit,
delivering higher packet processing efficiency.
This ANI mechanism is triggered by the rate of detected Physical Errors and it is
modifying different thresholds affecting the immunity to specific interference
types.
This feature, active by default, exists in all units with HW revision C and higher
running SW version 3.0 and higher. Starting in SW version 4.0, the processing
power of the system has been increased dramatically. When using version 4.0 the
