Key Descriptions
Turns off all frequency annotation. This includes the
FREQ DSP OFF
start and stop frequencies, center frequency, frequency
span, marker readouts, center-frequency step size, and
signal identification to center frequency. Once this key
is pressed, there is no way to display the frequency
data. To reactivate the annotation, press
Front-panel key access:
Adds an offset to the displayed frequency values,
FREQ OFFSET
including marker frequency values. It does not affect
the frequency range of the sweep. Enter the value using
the data keys, the step keys, or the knob. When this
function is active (that is, when the frequency offset is
not equal to 0 Hz), an F appears on the left edge of the
display.

center-frequency span mode. If the analyzer is in
start-frequency stop-frequency mode, the start
frequency is activated.
Front-panel key access:
Allows you to select a commonly used external mixing
FULL BAND
frequency band above 18 GHz. These bands are shown
in <Undefined Cross-Reference>. Use the step keys or
the knob to select a desired frequency band. The
selected band appears in the active function block.
Activating FULL BAND also activates the
harmonic-lock function. See the LOCK HARMONIC
softkey for more information.
Front-panel key access:
Executes a complete adjustment of the IF system. Once
FULL IF ADJ
activated, the softkey changes to STOP ADJUST
which, if pressed, stops the IF adjustment and returns
the analyzer to its previous state. During this
adjustment, the message IF ADJUST STATUS: <text>
appears in the active function area. Depending on
which portion of the IF system is being adjusted, either
AMPLITUDE or the specific resolution bandwidth (for
example, 300 Hz) is displayed in the message.
