The "Clock Settings" section is where the clock source is selected and - in the case of
an external source - the clock type.
The "Global Trigger/Clock Settings" button leads to a submenu for general trigger,
clock and external input settings.
Trigger In
The "Trigger In" section is used to configure the trigger signal for the digital modulation.
The current status of signal generation is indicated for all trigger modes.
Trigger Mode
Selects trigger mode.
"Auto" The digital modulation signal is generated continuously.
"Retrigger" The digital modulation signal is generated continuously. A trigger
event (internal with "Execute
Trigger" or external) causes a restart.
"Armed_Auto" The digital modulation signal is generated only when a trigger event
occurs. Then the digital modulation signal is generated continuously.
Button "Arm" stops signal generation. A subsequent trigger event
(internal with "Execute
Trigger" or external) causes a restart.
"Armed_Ret-
rigger" The digital modulation signal is generated only when a trigger event
occurs. Then the signal is generated continuously. Every subsequent
trigger event (internal with "Execute
Trigger" or external) causes a
restart.
The button "Arm" stops signal generation. A subsequent trigger event
(internal with "Execute
Trigger" or external) causes a restart.
"Single" The digital modulation signal is generated only when a trigger event
occurs. Then the signal is generated once to the length specified at
"Signal Duration". Every subsequent trigger event (internal with "Exe-
cute
Trigger" or external) causes a restart.
