G The [Mode 1] key provides the maximum FM deviation and
minimum RF output switching time. Noise level is highest in this
mode, as shown in the following table.
G The [Mode 2] key provides a median range of FM deviation and
RF output switching time, as shown in
Agilent 8643A defaults to Mode 2 operation.
