function
button to enter the Sweep mode.
(2)
Press

to set Sweep Time, the Time Span of the Sweep for which the Frequency
changes from the Start Frequency to Stop Frequency.
(4)
Press
F2
to select the Sweep Type. Linear means setting the Sweep with linear
spacing; Log means setting the Sweep with logarithmic spacing.
(5)
Use Start Freq and Stop Freq or Center Freq and Freq Span to set the range of the
frequency. Press
