Line: The instrument generates the trigger from the AC power input and synchroni-
zes the signal to the AC power frequency. Use this source if you want to analyze
signals related to the power line frequency, such as lighting equipment and power
supply devices. For the line trigger source, the edge trigger type is available.
●
Digital channels D0 to D15, serial bus
If options with trigger functionality are installed, the variety of trigger sources is
enhanced with specific trigger sources. These specific trigger sources are only
available for triggering on single event.
For the state trigger, this source is the "Clock source", the clock signal.
For the setup & hold trigger, this source is the "Data source", the data signal.
Remote command:
TRIGger:EVENt<ev>:SOURce on page 542
Type
Selects the trigger type. In a trigger sequence the trigger type is set for each condition.
The current trigger type is shown on the button and in the trigger label above the dia-
gram.

Remote command:
TRIGger:EVENt<ev>:TYPE on page 541
Level
Sets the voltage level or threshold for the trigger.
You can also drag the trigger level marker on the display, or turn the [Level] knob. To
set the trigger level to 50% of the signal amplitude, press the [Level] knob.
For the setup & hold trigger, this level sets the voltage level for the data signal. At this
level, the setup and hold time are measured.
For the timeout trigger, the trigger level is the threshold for the high and low signal
states.
Runt, window and slew rate triggers require two trigger levels (upper and lower), which
are defined as specific settings.
