Single / Extern Single mode (Sweep/List)

Figure 5-4: Single / Extern Single mode (sweep / list )

In single mode, you can specify, that the signal returns to the start value when a sweep
cycle has been completed.
See

"The Retrace function"

on page 117 for details.

●

The instrument generates a single sweep cycle.

●

Trigger mode "Manual". A trigger event initiates one sweep from the start value to
the end value.

●

"State = On" sets the signal to the start value: the sweep start frequency, the
sweep start power or the frequency-power value pair of the selected index in the
list.

●

Starts signal generation with a trigger event.
