(TBD)
hbGainStepLowRecovery Only applicable in fast recovery mode of peak
detect AGC. This sets the number of indices that the
gain index pointer should be increased in the event
of an HB Under Range Low Threshold Under Range
Event. 0 31 6
hbGainStepMidRecovery Only applicable in fast recovery mode of peak
detect AGC. This sets the number of indices that the
gain index pointer should be increased in the event
of an HB Under Range Mid Threshold Under Range
Event. 0 31 4
hbGainStepAttack The number of indices that the gain index pointer
should be decreased in the event of an HB High
Threshold Over Range event in AGC modes. The
step size in dB depends on the gain step resolution
of the gain table (default 0.5dB per index step).
0 31 2
hbOverloadPowerMode Sets the measurement mode of the HB detector. HB
uses I^2+Q^2 when set to 1. Otherwise the HB uses
max(I, Q) per sample.
0 1 0
hbUnderRangeMidThresh
ExceededCount Only applicable in fast recovery mode of peak
detect AGC. Sets number of individual overloads
above hbUnderRangeMidThresh (number of times
hbOverloadThreshCount was exceeded in
hbOverloadDurationCount) to cause an HB Under
Range Mid Threshold Overload Event. In Peak
Detect AGC mode, not having sufficient peaks to
cause the overload is flagged as an under-range
event and the gain is recovered by
hbGainStepMidRecovery.
0 255 3
hbUnderRangeLowThresh
ExceededCount Only applicable in fast recovery mode of peak
detect AGC. Sets number of individual overloads
above hbUnderRangeLowThresh (number of times
hbOverloadThreshCount was exceeded in
hbOverloadDurationCount) to cause an HB Under
Range Low Threshold Overload Event. In Peak
Detect AGC mode, not having sufficient peaks to
cause the overload is flagged as an under-range
event and the gain is recovered by
hbGainStepLowRecovery.
