Description
This sets the upper threshold of the HB detector.
This sets the lower threshold of the HB under range
threshold detectors. Used only when the fast recovery
option of the peak detect AGC mode is being utilized.
This sets the middle threshold of the HB under range
threshold detectors. Used only when the fast recovery
option of the peak detect AGC mode is being utilized.
Peak Detect Mode: Threshold used for gain recovery.
Peak Detect with Fast Recovery Mode: This sets the
highest threshold of the HB under range threshold
detectors.
Power Detect Mode: Threshold used to prevent
further gain increases if lowThreshPreventGainInc is
set.
Sets number of individual overloads above
hbHighThresh (number of times
hbOverloadThreshCount was exceeded in
hbOverloadDuractionCount) to cause an HB High
Over Range event. In AGC modes, this will result in a
gain decrement set by hbGainStepAttack.
Sets number of individual overloads above
hbUnderRangeHighThresh (number of times
hbOverloadThreshCount was exceeded in
hbOverloadDurationCount) to cause an HB Under
Range High 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 hbGainStepHighRecovery.
The number of indices that the gain index pointer
should be increased in the event of an HB Under
Range High Threshold Under Range Event.
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.
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.
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).
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.
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.
Only applicable in fast recovery mode of peak detect
AGC. Sets number of individual overloads above
hbUnderRangeLowThresh (number of times
