Function
The RF output amplitude range is shown in the following table. When
making amplitude changes, the instrument does not turn off the RF
output. The period of any over- or under-ranging that may occur
during level transitions is typically less than 30 ms.

Press IFM) to set the peak deviation for frequency modulation. Then
use the data entry keys to enter the desired value of deviation. The
values allowed depend on the RF frequency selected. See Chapter 4,
“Specifications” for peak deviation specifications.
Press (AM) to set the amplitude modulation range. Then use the data
entry keys to set the desired value of range. Values from 0 through
100% are allowed.
Press Idrvl] to set the peak deviation for phase modulation. Then use
the data entry keys to enter the desired value of deviation. The
values allowed depend on the RF frequency selected. See Chapter 4,
“Specifications” for peak deviation specifications.
