Address 27: Amplitude detector slope qualification delay
Table 10
Qualification delay: QUAL_SLOPE_DEL; notes 1 and 2
Notes
1.
DEL is the programmable compensation delay, in cycles of f
s
, between the qualifier and the analog zero crossing of
the read pulse circuit; DEL is a 2-bit unsigned value
SL selects the decay time of the amplitude detectors.
