FREQ
OFFSET
allows the user to input a frequency offset value that is added to the
frequency readout, to account for frequency conversions external to the
spectrum analyzer. Offset entries are added to all frequency readouts including
marker, start frequency, and stop frequency. Entering an offset does not affect
the trace. Offsets are not added to the span. Frequency offsets are entered
using the numeric keypad.
When a frequency offset is entered, its value is displayed on the bottom of the
screen (as opposed to reference level offsets, which are displayed on the left
side of the screen). To eliminate an offset, press FREQ OFFSET and 0
CENTER].
Pressing
@iZY]
also sets the offset to zero.

activates the center-frequency or start-frequency function and accesses
the menu that has the frequency functions. The center frequency or start
frequency value appears below the graticule on the screen.
Although the spectrum analyzer allows entry of frequencies greater than the
specified frequency range, using frequencies greater than the frequency span
of the spectrum analyzer is not recommended.
Note
When changing both the center frequency and the span, change the frequency
first since the span can be limited by the frequency value.
FULL
SPAN
changes the spectrum analyzer span to full span.

accesses the menu of gate control functions and the entrance to the gate utility
menus. The gate can be controlled independently or from within the gate
utility. The gate utility makes it easier to set up and manipulate the gate.
When the gate control functions are accessed under the Gate Control menu,
outside of the gate utility, they do not interact with the gate utility. Values
that are changed using these keys will not affect the gate utility settings and
