A noise component with adjustable amplitude can be superimposed on the overall
signal. This setting reduced the maximum level of the other signal components that
can be entered.
The checkbox enables or disables this function.

All Chan Sine
"Deactivated:" The higher-level sine wave is not being generated or being provided.
All concerning parameter fields disappear.
"Activated:" The higher-level sine wave is being generated and provided and
added channel-based to the overall signal with a percentage via the
"Gain" parameter field if the checkmark is set in the "All Chan Sine"
parameter field.

Arbitrary Mode
Operating mode of the arbitrary signal components (ARB and WAV files) within the uni-
versal generator function.
"Total Cont" All active arbitrary signal components are played back with the same
fixed playback time. The fixed playback time is yielded by the longest
sum of active arbitrary files and the associated delay. The time is dis-
played in the "Arbitrary" section in the "Time" parameter field. After
this time expires, the playback of the arbitrary components starts over
from the beginning, if necessary after the delay of the individual chan-
nel expires.
Each time a generator setting is changed, the arbitrary signal is auto-
matically recalculated, loaded and restarted. The loading process is
time-consuming (approx. 1/3 of the total playback time at a sampling
rate of 48 kHz). Therefore, this mode is suitable only for short arbi-
trary files.
