7.5.10 Calibration Data Clear
Once the calibration operation is executed, the {CORRECT ON/OFF} which indicates the cali-
bration being executed is set to ON. For re-calibration, the calibration data must be cleared.
Note:
Re-calibration operations differ between the case of normalize and the case of normalize &
isolation calibration and full calibration.
(1)
For normalize
Whether calibrated or not, the data is re-calibrated by pressing the {NORMALIZE}.
Note:
The normalize calibration data is overwritten by the re-calibration operation so that
the function for clearing the calibration data is not provided.
(2)
The case of normalize & isolation calibration and full calibration
If the calibration data of the normalize & isolation calibration and full calibration has already
been existed, in either case the calibration ON or OFF, the re-calibration cannot be execut-
ed. To re-calibrate the data, the data must be cleared.
The calibration data cannot be cleared during the calibration operation in order to prevent
miss operation. But if the sweeping condition is changed during the calibration, the data
can be cleared forcefully because the sweeping condition of each acquired calibration data
is changed.
The Setting and the Explanation
Press the [CAL] to call the calibration menu (1 of 2). (Refer to section A.4.)
Sets the {CORRECT ON/OFF} to OFF.
Press the {CAL MENUS} to call the full-calibration selection menu.
Press the {CLEAR CAL DATA} to call the clearing menu.
Press the {YES} to clear the calibration data.
Select any one of 1-port/2-port full calibration and enter the calibration operation.
CAUTION!
If the {CORRECT ON/OFF} is set to OFF, unless the calibration data is not cleared, the cal-
ibration can be set to ON again.
