See Chapter 5.8, "Timeout Trigger", on page 66.
"Line"
The line trigger uses the waveform of the power supply's alternating
line voltage (typically 50 Hz or 60 Hz AC) as the trigger signal source.
Use this trigger to detect issues related to the frequency of the power
grid.
The line trigger does not have any settings.
"Serial Bus"
Triggers on a serial bus. Requires that at least one protocol option
R&S RTB-K1, -K2, or -K3 is installed, a serial bus is configured, and
a decoded signal is available.
See Chapter 12.1.1, "Protocol - Common Settings", on page 165.

R&S RTB-B1 is installed.
"Extern"
Sets the external trigger input on the front panel as trigger source.
"B1 or B2"

the trigger type "Serial Bus" is selected.
Remote command:
TRIGger:A:SOURce on page 266
Hold Off, Hold Off Time
Enables the hold off and defines the "Hold Off Time". The next trigger occurs only after
the hold off time has passed.
The trigger hold off defines when the next trigger event is recognized after the current
trigger event. Thus, it affects the next trigger to occur after the current one. Hold off
helps to obtain stable triggering when the oscilloscope is triggering on undesired
events.
Remote command:
TRIGger:A:HOLDoff:MODE on page 267
TRIGger:A:HOLDoff:TIME on page 268
