Source = Line.
The spectrum analyzer triggers off of the AC line supply.
Source = RF Input and Type = Frequency Mask.
Setting Description
Violation These selections de fi ne the state or transitions of the signal used to de fi ne a trigger event.
Mask Editor Displays the Mask Editor so that you can create and edit Frequency Masks.
Load from fi le Invokes the Open dialog for selecting a previously saved frequency mask fi le.
RBW Sets the Resolution Bandwidth value to be used in the spectrum view. The value is
italicized when Auto is selected.
Actual This is a displayed value, not a setting. It is the RBW being used by the spectrum
analyzer; this value may not match the RBW requested (in manual mode).

Violation. Violations are state changes (or a sequence of state changes) de fi ned by the whether a point on
the signal falls within the frequency mask or outside the frequency mask. A True violation occurs if even a
single point on the trace falls inside the mask (above the mask’s lower edge). Conversely, a False violation
occurs if no points on a signal fall inside the mask (all trace points are below the mask’s lower edge).
