Operating Manual 1407.0806.32 ─ 21
Alternatively, the R&S
SMB 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
SMB-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
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.
"Train"
Requires option R&S
SMB-K27.
A user-defined pulse train is generated. Additional settings for the
pulse train are available in the menu after selection of the pulse train
mode (see
Chapter 5.5.4.2, "Pulse Train Generation"
A pulse train is a sequence of pulses with user-defined on and off
times. The on-time/off-time value pairs are defined in a pulse train list.
The currently used pulse train file is displayed in the sub menu.
