3.1.6 Frequency
Opens a menu that enables you to control the Frequency parameters of the
instrument.
3.1.6.1 Settings
Contains controls that pertain to the X-Axis parameters of the measurement. These
parameters control how data on the vertical (Y) axis is displayed and control
instrument settings that affect the horizontal axis.
Center Frequency
Sets the frequency that corresponds to the horizontal center of the graticule (when
frequency Scale Type is set to linear). While adjusting Center Frequency, Span is
held constant, which means that both Start Freq and Stop Freq will change.
In measurements that also have Start Freq and Stop Freq controls, pressing Center
Frequency sets the frequency entry mode to Center/Span. In Center/Span mode,
the center frequency and span values are displayed below the graticule, and the
default active function in the Frequency menu is Center Frequency. In the
