When generator settings have been changed or a measurement has been started, the
burst starts with the positive sinusoidal half-wave of the burst duration ("On Time"). The
"Burst On Delay" parameter is used to set a defined delay time.
Function
Selects the sine burst signal.
Remote command:
SOURce:FUNCtion

BURSt
Sweep Ctrl
Used to activate the sweep system. The frequency and level of the burst signal can be
varied within a selectable range from the start to the stop value. If one of these param-
eters is selected as the x-axis, the measured values can be displayed as a curve in the
Sweep Graph graphical window.
The individual sweep points are calculated linear or logarithmic between start and stop
values or read out of a file.
The individual sweep points are automatically forwarded in a defined time grid 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.
Frequency
Used to set the frequency of the sine wave. The value range depends on the analog
bandwidth set in the Generator Config panel or the digital clock rate.
Remote command:
SOURce:FREQuency<n2>
on page 697
Voltage
Used to set the level of the sine wave during the burst duration. The maximum value
depends on the configured DC offset. In the analog generator, the maximum total volt-
age also depends on the settings for Output Type and Max Voltage in the Generator
Config panel.
Remote command:
SOURce:VOLTage<n2>
on page 699
On Time
Used to set the burst duration. Entered as a fixed time or as a number of periods
(cycles) of the sine-wave frequency.
Minimum value: 1 Sample
Maximum value: 60 s – 1 Sample
With SINGLE, the burst signal is output once, with START the burst signal is output
again with every completed measurement. In this operating mode, the set measure-
ment time determines the repetition rate of the burst signal.
