Hysteresis transparency
Defines the transparency of the hysteresis area above or below the trigger level. The
hysteresis is only visible if "Show trigger lines permanently" is enabled.
3.3.6 Control
The settings and functions of trigger control define when the instrument triggers. They
affect all kinds of trigger events and all triggers in a trigger sequence.
In addition to the settings in the dialog box, you need the RUN keys on the front panel to
start and stop the triggering and thus the acquisition.
The R&S RTO can provide an external trigger signal to synchronize the measurements
of other instruments. The trigger out signal is also adjusted and enabled in the "Con-
trol" tab.
Trigger mode
Sets the trigger mode which determines the behavior of the instrument if no trigger occurs.
The current setting is shown on the trigger label on top of the signal bar.
To toggle quickly between "Auto" and "Normal" mode, use the MODE key on the front
panel (in "Trigger" section).
"Auto"
The instrument triggers repeatedly after a time interval if the trigger
conditions are not fulfilled. If a real trigger occurs, it takes precedence.
This mode helps to see the waveform even before the trigger conditions
are set correctly. The waveform on the screen is not synchronized, and
successive waveforms are not triggered at the same point of the wave-
form. The time interval depends on the time base settings.
