You can arbitrarily select a value within the range of the start and stop values by
setting the frequency, power or index using the corresponding remote control com-
mand. There is no ascending or descending order.

The Retrace function
Retrace is a function especially designed for "Single" sweep modes, when the sweep
signal follows a sawtooth shape. Working in this mode, the instrument performs a sin-
gle sweep cycle when a trigger event occurs. The signal generation stops at the set
end point (stop frequency or stop level), and waits for the next trigger event.
In this state, the upper value of the signal remains at the output until the next cycle
starts. In particular, if you generate a level sweep signal, the high amplitude of the sig-
nal is output for a certain time. To protect the DUT from overload, the retrace function
immediately resets the signal value to the start value at the end of a sweep cycle. It
shifts down the power, or frequency value during the waiting period.
