Function Details

SMU 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

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.

The EasyEXPERT does not support the step delay time. It is available only for the

GPIB remote mode.
