is 2-3, 2-3 (Optional) is displayed. The display after the execution of the omittable thru/line
measurement is
2-3 Thru/Line.
For the softkey of an omittable line/match measurement, (Optional) is displayed as in the
case of the omittable thru/line measurement. For example, when the omittable line/match
measurement is 2-3,
2-3 (Optional) is displayed.The display after the execution of the
omittable line/match measurement is
2-3 Line/Match.
The softkeys (Fwd and Rvs) for forward measurement and reverse measurement for the
omittable line/match measurement do not change.
Table 4-5 Required measurements and omittable measurements for simplified 4-port
TRL calibration
Required measurements Omittable measurements
1-2, 1-3, 3-4 1-4, 2-3, 2-4
NOTE For the simplified 4-port TRL calibration, (Recommended) is displayed on the softkey of
the omittable thru/line measurement. For example, when the omittable thru/line
measurement is 2-3,
2-3 (Recommended) is displayed. The display after the execution of
the omittable thru/line measurement is
2-3 Thru/Line, and the display for the remaining
omittable thru/line measurement is
2-3 (Optional).
For the softkey of an omittable line/match measurement, (Recommended) is displayed as
in the case of the omittable thru/line measurement. For example, when the omittable
line/match measurement is 2-3,
2-3 (Recommended) is displayed.The display after the
execution of the omittable line/match measurement is
2-3 Line/Match, and the display for
the remaining omittable line/match measurement is
2-3 (Optional).
The softkeys (Fwd and Rvs) for forward measurement and reverse measurement for the
omittable line/match measurement do not change.
For the simplified 4-port TRL calibration, up to three thru/line measurements and
line/match measurements can be omitted, but omitting all of them results in poor accuracy.
