The signal generator is now configured to output a 0 dBm, phase-modulated carrier at 3 GHz with a 0.25 p
radian deviation and 10 kHz rate. The shape of the waveform is a sine wave. (Notice that sine is the default
for the

.
The
FM
and
RF ON
annunciators are now displayed. This indicates that you have enabled phase modulation
and the signal is now being transmitted from the RF OUTPUT connector.
