Trigger mode
Determines how the trigger is evaluated.
"Norm" Each time a trigger event occurs, a measurement is performed.
"Auto" Each time a trigger event occurs, a measurement is performed.
If no trigger event occurs during a predefined waiting period, a mea-
surement is performed without a trigger. This helps you determine the
required trigger level.
"Single" When the trigger event occurs, a single measurement is performed.
Trigger Source
Determines how often and when a new sweep is performed.
"Ext." A measurement is performed each time a trigger signal from a con-
nected external trigger device is received. The trigger device must be
connected to the "Trigger In" connector on the rear panel of the
R&S
EVSF1000.
"Level" A measurement is performed when the input signal reaches the
defined trigger level.
Trigger Edge
For external triggering, this setting defines whether a measurement is performed when
the positive (rising) or negative (falling) edge of the trigger signal is received. Select the
key repeatedly to toggle between the two settings.
