I/V-t Sampling Measurement
Time Data and Index
To obtain the time data, enter a variable name (e.g. Time) into the Time Stamp
Name field of the Channel Setup screen. The time data can be obtained after the
linear sampling measurement is executed, and can be expressed by the following
formula.
Time = Hold Time + Interval [(Index 1) + N] +
Time : Variable name set to the Time Stamp Name field of the Measurement
Setup screen. Time data is returned.
Index : Variable name set to the Index Name field of the Measurement Setup
screen. Data index is returned. Maximum value is 2147483647.
Interval : Sampling interval. Defined in the Measurement Setup screen.
Hold Time : Hold time. Defined in the Measurement Setup screen.
N : Number of samplings performed while one point measurement was
executed. This value is 0 if the sampling interval is longer than the
measurement time.
: Time from the start of one point measurement to the start of
integration by the A/D converter.
If the sampling interval is longer than the actual measurement time, measurement
channels repeat measurement with the specified sampling interval. However, if the
sampling interval is shorter than the measurement time, the measurement interval
will be integral multiples of the specified sampling interval. Example for Hold Time
=10 ms, Interval=5 ms, and the following Time values is shown in
Figure 4-10. In
this case, N=3.
• Time (for Index=1) = 10 ms = 10 + 5 [(1 1) + 0] ms
• Time (for Index=2) = 30 ms = 10 + 5 [(2 1) + 3] ms
