DETECTOR FUNCTIONS
Address 24: QUAL_FIX_POS and Address 25: QUAL_FIX_NEG
QUAL_FIX_POS and QUAL_FIX_NEG contain the positive and negative fixed threshold (8-bit signed) values.
Address 26: Variable gain factors
Table 9
Gain factors: QUAL_VAR_GAIN; note 1
Note
1.
GP and GN set the factors of the measured amplitude that are to be used as variable qualifier thresholds: GP for the
positive peaks and GN for the negative peaks.
