calculated without a part of the thru measurement data. Therefore, the
following should be considered when measuring data for the simplified full
3-/4-port calibration.
The standard used for measurement must match its definition value.

Use a standard that provides good repeatability (stability).
•
Do not omit the length of the thru when defining the standard.
•
When using a user-created standard, verify the definition
•
value.
For the N connector, remember that it has two different types:
•
male and female.
Assure high reliability and repeatability for measurement.

Reduce the difference in external environment (such as
•
temperature difference) between the time when measuring
calibration data and when measuring actual data.
Set the power level of the stimulus signal sufficiently small so
•
that compression does not occur.
Narrow the IF bandwidth.
•
Increase the averaging factor.
•
Use a cable that has robust amplitude/phase characteristics
•
against bending.
Use high-precision connectors.
•
Simplified 3/4-port TRL calibration
This function is available with Firmware revision A.06.50 or
•
greater.
The simplified 3/4-port TRL calibration calculates the calibration
•
coefficient by skipping part of the thru/line measurement (or
line/match measurement) that is necessary for normal 3/4-port
TRL calibration.
You need to give consideration to the same conditions for the
•
simplified 3/4-port TRL calibration as those for the simplified full
3/4-port calibration listed above.
