The signal generator is now configured to output a 0 dBm, pulse-modulated carrier at 2 GHz with a
100-microsecond pulse period and 24-microsecond pulse width. The pulse source is set to Internal Free Run.
(Notice that Internal Free Run is the default for the
Pulse Source
softkey.)
To Activate Pulse Modulation
Follow these remaining steps to output the pulse-modulated signal.
1. Press
Pulse Off On
to On.
2. Press
RF On/Off
.
The
Pulse
and
RF ON
annunciators are now displayed. This indicates that you have enabled pulse
modulation and the signal is now being transmitted from the RF OUTPUT connector.
