Data sent from the HP 1652B/53B is raw data and must be scaled for
useful interpretation. The values used to interpret the data are the X and
Y references, X and Y origins, and X and Y increments. These values are
read from the waveform preamble or by the queries of these values.
The formula to convert a data value returned by the instrument to a
voltage is:
voltage = [(data value - yreference) x yincrement] + yorigin
The time value of a data point can be determined by the position of the
data point. As an example, the third data point sent with XORIGIN =
formula:
time = [(data point number - xreference)
time = [(3 - 0) x 2ns] + 16ns = 22ns.
The trigger data point can be determined by calculating the closest data
point to time 0.
