4.4.7 Terminating Entries with Confirmation
The instrument behaves different by the termination of entries deppending on the param-
eter type and the way this parameter is set.
Confirming settings
►
To confirm the settings, press the rotary knob or one of the UNIT keys (see also
chapter 4.4.5, "Working with Units ", on page 65) .
Note: Variations by means of the rotary knob are immediately set.
Confirming multiple values
In some cases, like for instance when editing data in a user correction table, it is useful
first to enter few values and to confirm them together. Such settings require additional
confirmation. Not yet confirmed settings are displayed on a yellow background as an
indication that the currently displayed values do not represent the target signal.
► To confirm these settings, select the "Save" or "Accept" button, respectively.
Confirming parameters with On/Off state
Most of the instrument functions with enabled and disabled states are calculated and
effective only after this functions have been enabled. However, there are functions like
the frequency variation of the reference oscillator for instance, that are immediately set
after confirmation.
► To confirm a parameter with On/Off state, enable the parameter.
4.4.8 Restoring the Previous Value
Parameter variations with the rotary knob are immediately set and therefore not reversi-
ble.
Normally, values cannot be restored in the case of mouse control because no explicit
confirmation is required in this case and entries are automatically confirmed when the
entry or selection field is exited.
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.
► 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.
