Retrace
For "Shape = Sawtooth" and "Mode = Single/External Single", enables changing the
signal to the start value while it is waiting for the next trigger event. It returns to the
start level or start frequency until the next trigger is applied.
See "The Retrace function" on page 500.

Shape
Selects the waveform shape of the sweep signal.
See also Chapter 8.7.2.2, "Sweep Signal Shapes", on page 503.
"Sawtooth"
The sweep runs from start to stop frequency. The subsequent sweep
starts at the start value, i.e. the shape of the sweep sequence resem-
bles a sawtooth.
"Triangle"
The sweep runs from start to stop value and back, i.e. the shape of
the sweep resembles a triangle. Each subsequent sweep starts at the
start frequency.

Spacing
In "RF and LF Frequency Sweep" mode, "Spacing " selects the mode for calculating
the frequency interval, which increases or decreases the current frequency at each
step.
To determine the step size, select the parameter Step Linear/Step Logarithmic.
In "RF Combined Sweep" mode, the parameter indicates that the step intervals are lin-
early (straight proportional) distributed, i.e. the intervals have the same size. The fre-
quency / level range and the Dwell Time time determine the calculated step size.
