3 0x02 1 Absolute/Relative
time crossings for
band detector in
decay mode.
0: Absolute
1: Relative
If time crossings are specified as Absolute Number
4 0x03 3 Number of samples
at F
BAND
(Band
Detector Clock
Rate) for Band
detector 1 to
declare decay for
Band 1
5 0x06 3 Number of samples
at F
BAND
(Band
Detector Clock
Rate) for Band
detector 2 to
declare decay for
Band 2
If time crossings are specified as Relative Number
4 0x03 2 Fraction of samples
crossing signal
threshold in given
time constant for
Band detector 1 to
declare decay for
Band 1.
5 0x03 2 Fraction of samples
crossing signal
threshold in given
time constant for
Band detector 2 to
declare decay for
Band 2.
If Band Detector Bandwidth Selection is set to output bandwidth then F
BAND
= Output Rate.
If Band Detector Bandwidth Selection is set to higher bandwidth then use the table below.
