Note the following correlations:
●
The number of received data values matches the number of samples indicated in the
header.
●
The time of the first sample (XORigin) matches the start time Xstart indicated in the
header.
●
The Y-increment adjusts to the data length defined in the data format (8 or 16 bit).
Data conversion
Definition: the sample numbers start with 0 and end with record length - 1.
Sample time

n
= n * xIncrement + xOrigin
First sample: t

= -4.998000058E-7 (= Xstart)
Last sample: t
