FREQUENCY

This 

 lets you set a value for the frequency span in the center

frequency/frequency span mode of swept frequency operation.

Press 

 and use the entry area to enter the desired value.

The synthesizer sweeps from the span below to above the center

frequency.

Certain center frequency and frequency span combinations cause the

synthesizer to limit the value entered. In general, any combination
that causes the synthesizer to exceed its minimum or maximum
specified frequency is limited.

 activates swept frequency mode and makes the start

frequency parameter the active function. Press

be separated by at least 2 Hz in order to remain in the frequency
sweep mode. If start=stop frequency then the zero span mode is
entered.
