Restoring values
In the case of front-panel control or operation from the keyboard, previous values can
be restored as long as the new value is not confirmed, i.e. the entry is not completed.
â–º To restore the values, press the ESC key.
Restoring values that require confirmation
All settings that are not confirmed with the "Accept" button but require this additional
confirmation can be restored.
1. Press the ESC key.
A confirmation query is displayed.
2. Confirm with "OK" to abort the changes.
Select "Cancel" to return to the dialog. The previous selected settings are dis-
played.
Restoring values after an extended calculation has been started
Calculation and setting might require different period of time. Many settings are made
without noticeable calculation times; such operations are indicated by a "BUSY" mes-
sage displayed in the status field of the header section.
A window with a progress indicates that the instrument performs an extended calcula-
tion that requires longer calculation time. The termination of such a calculation restores
the previous values.
â–º Press the ABORT button to terminate the calculation.
All previous values are restored.
4.5 Editors
The R&S SMB provides user-friendly editors for defining lists. Lists containing fre-
quency and level value pairs are used for the list mode and the user-defined level cor-
rection.
The lists are saved to files and may thus have any length. The file name of the lists and
the directory to which the files are saved are user-selectable. The file prefix is different
for each list type and is permanently assigned by the system.
For information about file handling and overview of the automatically assigned file pre-
fixes, refer to Chapter 4.7, "File Management", on page 82.
