StartCycle β is the starting time for cycle measurements. It is a floating-point
number with values between 0.0 and (ξξξξξξξξξξξξ β 1.0), inclusive.
ξξξξξξξξξξ = ξξξξξξξ
EndCycle β is the ending time for cycle measurements. It is a floating-point
number with values between 0.0 and (ξξξξξξξξξξξξ β 1.0), inclusive.
ξ
ξξξξξξξ = ξξξξξξξ
Waveform[<0.0 ... RecordLengthβ1.0>] β holds the acquired data.
TPOS β is the location of the sample just before the trigger point (the time
reference zero sample). In other terms, it contains the domain reference location.
This location is where time = 0.
TSOFF β is the offset between ξξξξ and the actual trigger point. In other
words, it is the trigger sample offset. Values range between 0.0 and 1.0 samples.
This value is determined by the instrument when it receives a trigger. The actual
zero reference (trigger) location in the measurement record is at
(ξξξξ+ξξξξξ).
