"Step / Extern Step"
Generates the sweep signal step-by-step, manually triggered.
"Extern Start/Stop"
Generates a continuously repeating sweep signal that is started,
stopped, and restarted by subsequent external trigger events.
The sweep steps are performed automatically, controlled by the dwell
time.

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.
