For the above example, the array variables sc[], md[], st[], and tm[] will contain the
following data.
sc[n]: Sweep source setup data (voltage).
md[n]: Measurement data (current).
st[n]: Status for the md[n] data.
tm[n]: Time stamp data (measurement start time) for the md[n] data.
where, n = 0 to 10 (integer).
