4.4.7 Terminating Entries with Confirmation
The instrument bahaves different by the termination of entries deppending on the param-
eter type and the way this parameter is set.
Confirming settings

chapter 4.4.5, "Working with Units ", on page 102) .
Note: Variations by means of the rotary knob are immediately set.
Confirming multiple values
In some case, like for instanse when configuring the carriers for a multicarrier CW signal
in a carrier 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 this settings, select the "Accept" button.
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.
If time-consuming calculations are required, signal generation is automatically switched
off and calculation is interrupted to allow the user to make further settings. Calculation is
restarted with the RECALCULATE key and the modulation is switched on again when
the calculation is completed.
Preventing recalculation
If an instrument function requires several parameter settings, switch the function off to
prevent a recalculation.
Enable the function after the entire configuration of the settings have been compleated.
The signal is recalculated only once.
