of the calibration sweep and the result can be monitored in the diagram. In case of an error (e.g. if the
measurement result shows that the calibration standard was not connected properly),
Abort Sweep
immediately terminates the sweep.
After completing the sweep the analyzer generates a short sound and a green checkmark appears in
the checkbox. Measurements can be repeated as often as desired. Newer results overwrite older
measurement data.
The trigger settings are ignored for calibration sweeps. Each calibration sweep is started without
delay (Free Run measurement). This also holds for power calibration sweeps.
Checks for the calibration sweep
If the sweep range of the active channel exceeds the validity range of the standard model (defined by
Min. Freq. and Max. Freq. in the Add/Modify Standard dialog) the analyzer displays a notice box
(confirm with OK).
The Measure Standards dialog provides further controls:
•
Keep Measurement Data for >Repeat Cal< causes the raw measurement data of the
standards to be stored after the calibration is completed. This enables the Repeat Previous
Cal... command, which can be used to optimize a previous calibration without repeating the
measurement of all standards. If Keep Measurement Data... is not active, then the raw
measurement data of the standards is deleted and the analyzer only stores the system error
correction data. Deleting the raw data saves disk space.
•
Apply is enabled as soon as data have been acquired for all standards. The button starts the
calculation of the system error correction data and closes the calibration wizard. The current
instrument settings are stored with the correction data. To avoid incompatibilities, older system
error correction data is deleted unless it has been transferred into a
Cal Pool using the
Calibration Manager.
The Keep Measurement Data for >Repeat Cal< setting is valid for the current calibration only. To
activate this function in general, use the parameter in the User Interface tab of the Sytem Config. dialog
(menu System – System Config ).
Checks during the calculation of correction data
Incompatibilities between the selected calibration type, the standards and the channel settings may
cause the calibration to be inaccurate . The analyzer auto-detects potential sources of errors and
displays appropriate, self-explanatory notice boxes.

Repeat Previous Cal
Reopens the Measure Standards dialog of the calibration wizard to repeat and optimize the previous
calibration without necessarily repeating the measurement of all standards.
Repeat Previous Cal is active only if Keep Measurement Data for >Repeat Cal< in the Measure
Standards dialog was enabled when the last calibration for the active channel was successfully
completed.
