Sampling Measurement Data
Measurement parameters of sampling measurement are set to the NAME column of
the DISPLAY: DISPLAY SETUP screen. Available parameters and example
parameters for the NAME field are listed in the table below:
Measurement start time can be expressed by the following fomula. This formula is
available for the measurement points before starting the discarding operation for the
linear sampling or thinned-out sampling. For logarithmic sampling, this is available
for the measurement points in the first decade.
@TIME = Thold + Tinterval ´ [(@INDEX - 1) + N]
where,
@TIME : Measurement start time.
Thold : Hold time.
Tinterval : Sampling interval.
@INDEX : Data index.
N : Number of triggers between two nearest measurement points. This
value is 0 if the sampling interval is enough longer than the
measurement time.

Name
Meanings of Parameter
@TIME Measurement start time. This is the time the measurement unit
starts one point measurement. This is different from timing of the
measurement trigger sent every sampling interval.
@INDEX Data index. Integer. This is the index numbered to measurement
data stored in memory.
V1 for example, SMU1 voltage output value or measured value.
I1 for example, SMU1 current output value or measured value.
