Function Details
Measurement Time
Measurement Time
Measurement time depends on aperture time, measurement range, and other
measurement conditions, and can be expressed by the following formula:
Measurement time = Aperture time + Overhead time
Aperture time is the time required for measurement, and does not include such
factors as range change or data compensation, which would be the overhead time.
Aperture Time
Aperture time is the time required to acquire the measurement data. For accurate and
reliable measurement, the aperture time should be increased.
The aperture time is set by using the Measure Speed parameter on the Single view.
See
“Speed” on page 4-11 .
Overhead Time
Overhead time is the time required for range change, etc. This time depends on the
measurement condition, and cannot be specified. Major elements of the overhead
time are:
• Range change time during measurement (when measurement ranging mode is
set to AUTO)
• Range change time at the start of a measurement (when the measurement range
is less than the compliance value)
To Control Source/Measure Timing
The source output and measurement timing can be controlled by the following
parameters. See
Figure 6-1 . This figure shows an example of sweep output. For a
bias output, focus the shape of a sweep step only.
1. Source delay
The source delay time is defined as the time from trigger to start of a source
output.
