Pulse Modulation
During pulse modulation, the RF carrier waveform is modulated by the pulse signal.
To Enable Pulse Modulation
Press Pulse  Switch to select “On” or “Off”.
 On: enable the pulse modulation function. The backlight of Pulse goes on and
the Pulse label is displayed in the function status area in the user interface.
 Off: disable the pulse modulation function and this is the default state.
To Select the Modulation Source
Press Pulse  Source to select “Ext” or “Int” modulation source.
1. Internal Source
After selecting “Int”, the internal modulation source is turned on. At this point,
the instrument provides the modulating signal and you can set the pulse mode,
pulse period and pulse width of the modulating signal.
2. External Source
After selecting “Ext”, Mode, Period, Width Trig Mode and Pulse Out are
grayed out and disabled. The RF signal generator receives the external pulse
signal input from the [PULSE IN/OUT] connector (as shown in the figure
below) at the rear panel as the modulating signal.
