Alternatively, the R&S SMC provides the pulse generator parameters in the "Pulse
Modulation" dialog accessed via the "Modulation" block.
The dialog provides the settings for the pulse characteristics and trigger mode.
Depending on the selected modulation source and pulse mode the provided
parameters vary.
Note: Extended features as the generation of double pulse signals with selectable
pulse widths and periods, or selectable trigger mode require option R&S SMC-K23.
Video Sync Signal State - Pulse Generator
Switches on/off the output of the video/sync signal at the PULSE VIDEO connector.
The signal output and the pulse generator are automatically switched on with activation
of pulse modulation if pulse generator is selected as modulation source. The signal
output can be switched off subsequently.
Pulse modulation of the RF carrier is activated in the "Pulse modulation" menu of the
"Modulation" block.
Remote command:
[:SOURce<hw>]:PGENerator:STATe on page 308
Pulse Mode - Pulse Generator
Sets the mode of the pulse generator.
"Single"
A single pulse is generated in one pulse period.
"Double"
Two pulses are generated in one pulse period. Additional settings for
the double pulse are available in the menu.
Remote command:
[:SOURce<hw>]:PULM:MODE on page 326
Pulse Period - Pulse Generator
Sets the period of the generated pulse. The period determines the repetition frequency
of the internal signal.
Remote command:
[:SOURce<hw>]:PULM:PERiod on page 327
Pulse Width - Pulse Generator
Sets the width of the generated pulse. The width determines the pulse length. The
pulse width must be at least 20 ns less than the set pulse period.
