Address Size Type Value Description Values
4541 2 Long SOS_SUB_ARRAYS SOS Sub Array Size
4543 2 Long
SOS_NORMALIZE_
FLAG
0 = NO normalization in the frequency domain. 1 =
norm
alization in the frequency domain.
4545 2 Long
SOS_DIFFERENCIN
G_FLAG
0 = NO differencing in the frequency domain. 1 = 1st
orde
r differencing in the frequency domain. 2 = 2nd
order differencing in the frequency domain.
4547 2 Long
SOS_OP_MODE_S
ETTINGS
Determines which ridge to use for SOS calculation. Also
determi
nes which SOS parameter to leave fixed or
calculate and whether or not to use Linear/Log KW diff.
0 = Use right and left ridge
averag
ed, 1 = Use right ridge only,
2 = Use left ridge only, 4 = Enable
SOS auto frequency calculation, 8
= Enable SOS power weighting to
auto-frequency calculation, 16 =
Linear KW diff enable, 32 = Log
KW diff enable.
4549 2 Long SOS_SELECT_NUM SOS Selection Threshold.
4551 2 Long
SOS_MIN_FREQ_P
TS
This value selects the minimum number of frequency
points that wil
l be used in the SOS calculation. If this
number is not met then the calculation is not performed
and an error is reported.
4553 2 Long
SOS_NUM_PTS_LE
FT
The number of frequency points used from the left ridge
of the k-w plo
t.
4555 2 Long
SOS_NUM_PTS_RI
GHT
The number of frequency points used from the right ridge
of the k-w plo
t.
4557 2 Long
AGC_THRESHOLD_
HIGH
Upper threshold limit for sensor readings. Used to detect
H
igh Threshold sensor readings during AGC mode
functions.
4559 2 Long
AGC_THRESHOLD_
LOW
Lower threshold limit for sensor readings. Used to detect
Low Th
reshold sensor readings during AGC mode
functions.
4561 2 Long
AGC_PERCENT_TH
R
ESHOLD_HIGH
Represents the percentage value of High Threshold
faults req
uired to be detected before asserting an
Excessive Gain condition during AGC functions.
