Measurement Time
Overhead Time
The overhead time is the time required for range changing and so on. This time
depends on the measurement condition, and cannot be specified. Major elements of
the overhead time are:
• Range changing time during measurement (when measurement ranging mode is
set to auto or limited auto)
• Range changing time at measurement start (when the measurement range is less
than the compliance value)
To Specify Source Output Time
As shown in the discussion of the overhead time, you cannot specify the
measurement time. However, in sweep measurement mode, you can specify a
source output time that includes the measurement time. To specify the source output
time, set the delay time and the step delay time. The step delay time is defined as the
time from the measurement trigger up to the trigger for changing the source output
value. See the figure below.
The step delay time must cover the measurement time to keep the source output time
constant.
These values can be set by the WT command.
