The ANALYZER softkey selects the ANALYZER mode.
The functions provided are those of a conventional
spectrum analyzer. The analyzer measures the frequency
spectrum over the selected frequency range with the
selected resolution and sweep time, or, for a fixed
frequency, displays the waveform of the video signal.

Frequency and Span Selection – FREQUENCY Key Group
The FREQUENCY key group is used to specify the frequency axis of the active measurement window.
The frequency axis can be defined either by the start and stop frequency or by the center frequency and
span. For the case when two measurement windows (SPLIT-SCREEN) are displayed simultaneously,
data entered are always related to the window selected in the SYSTEM-DISPLAY menu.
When one of the keys CENTER, SPAN, START or STOP is pressed, its value can be specified in an
entry window. At the same time, a softkey menu appears, which allows selecting the optional
parameters.

The START key opens a menu which displays the various
options for setting the start frequency of the sweep.
The START MANUAL softkey is automatically active and
opens the entry window for manual input of the start
frequency. At the same time, the coupling of the parameters is
set to STOP FIXED
The STOP FIXED, SPAN FIXED and CENTER FIXED
softkeys are mutually exclusive selection switches. Only one
of these switches may be active at any one time. The
frequency coupling selected by the softkeys defines which of
the dependent parameters stop frequency, center frequency
and span is to remain constant when a change in the start
frequency is made.
The FREQ AXIS LIN/LOG softkey switches between linear
and logarithmic scaling of the frequency axis.
