Dither
In the digital generator, a noise component with adjustable amplitude can be superim-
posed on the signal. The checkbox enables or disables this function.
The parameter fields for Dither do not appear in the analog generator.
Remote command:
SOURce:SINusoid:DITHer:STATe

Sweep Ctrl
Used to activate the sweep system. The center frequency (in the IEC 118 mode) or the
upper frequency (in the IEC 268 mode) or the total level (Total Voltage) of the signal
can be varied from the start to the stop value. If frequency or level is selected as the x-
axis, the measured values can be displayed as a curve in the Sweep Graph graphical
window.
Sweep points: Linear or logarithmic between Start and Stop or read out of the file.
Forwarding: Automatic in a defined timeframe or synchronized to the measurement
time of the analyzer. All setting parameters of the sweep system are described in detail
in
Chapter 5.9, "Sweeps" , on page 285.

Mean Freq
Used to set the center frequency (in the IEC 268 mode).
Remote command:
SOURce:FREQuency:MEAN
on page 707
Upper Freq
Used to set the upper frequency (in the IEC 118 mode).
Remote command:
SOURce:FREQuency<n2>
on page 697
Diff Freq
Used to set the frequency difference of the two sine waves.
Remote command:
SOURce:FREQuency:DIFFerence
on page 706
Total Voltage
Used to set the level of the overall signal. The maximum value depends on the config-
ured DC offset. In the analog generator, the maximum total voltage also depends on
the settings
"Output Type " on page 197 and "Max Voltage" on page 199 in the Gener-
ator Config panel.
