5.2 General Trigger Settings
The keys in the Trigger section provide all functions to set up the trigger.
AUTO/NORM trigger modes
Sets the trigger mode. The Trigg'd LED lights up if the instrument found a trigger event.
"AUTO"
In "AUTO" mode, the screen always displays a signal. If a signal ful-
fills the trigger conditions, the oscilloscope synchronizes with this
event and triggers when the condition is met. If a signal that does not
fulfill the trigger condition, the oscilloscope generates a trigger event.
With auto mode, you can see the input signals at any time, regardless
of the trigger condition.
"NORMAL"
In "NORMAL" mode, the signal is displayed if the trigger condition is
met. The instrument shows the signal that was triggered last. If no
trigger occurs, no waveform is acquired and the last triggered wave-
form is displayed. If no waveform was captured before, nothing is dis-
played.
SINGLE
To ensure that only a signal that meets the trigger condition is detected and displayed,
press the SINGLE key. The key is highlighted in white when the SINGLE mode is
active. In normal trigger mode, the trigger system is now activated, and the RUN/STOP
key is blinking. If the trigger condition is fulfilled, the instrument triggers, data is stored
and displayed, and the oscilloscope switches to "STOP" mode (red RUN/STOP key.
TYPE
Opens a menu to select the trigger type, and to set the hold-off time.
The following trigger types are available:

Serial trigger if at least one of the protocol options R&S RTC-K1, R&S RTC-K2, or
R&S RTC-K3 is installed.
HOLD OFF
The trigger hold-off time indicates how long the oscilloscope waits after a trigger event
until the trigger system is ready again. The next trigger occurs only after the hold-off
time has passed. Hold-off helps to obtain stable triggering when the oscilloscope is
triggering on unwanted events. Changing the time base does not impact the selected
hold-off time.
The hold-off time is set in the "Trigger Type" menu.
SOURCE
Opens a menu to set the trigger source. You can trigger on:
