Preparation for Accurate Measurement (Executing Correction)
Obtaining Correction Data
The table below summarizes how data is set up, depending on the setup at
execution.
Measurement conditions during data measurement
The data for the SHORT correction is measured under the following
measurement conditions:
• Measurement range mode: auto range mode
• Measurement time mode: 8
• Output impedance of measurement signal source: 20 Ω
For other settings, such as averaging and trigger delay, the measurement
conditions set up at execution are used for measurement.
Measurement procedure
For more information about the measurement procedure for the data used in
the SHORT correction, refer to “Measuring data for SHORT correction” on
page 47.
