Pulse Modulation (Option DSG800-PUM)
During pulse modulation, the RF carrier waveform is modulated by the pulse signal.
Press MOD Pulse Mod to enter the pulse modulation parameter setting menu.
To Turn on Pulse Modulation
Press Switch to select "On" or "Off".
On: turn on the pulse modulation function. The PUL label in the function status
area in the user interface is illuminated.
Off: turn off the pulse modulation function and this is the default state.
Note: If a sweep manner is selected and the step sweep time is lower than 50 ms,
"You can turn on the Pulse Modulation when sweep time is greater than 50ms" will
be displayed in the user interface when pulse modulation is turned on.
To Select the Modulation Source
Press Source to select "Ext" or "Int" modulation source.
1. Internal Source
When "Int" is selected, the internal modulation source is turned on. At this point,
the internal pulse generator of 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
When "Ext" is selected, 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.
