The STOP key opens a menu which displays the various
options for setting the stop frequency of the sweep.
The STOP MANUAL softkey is automatically active and opens
the entry window for manual input of the stop frequency. At the
same time, parameter coupling is set to START FIXED.
The START FIXED, CENTER FIXED and SPAN FIXED
softkeys are mutually exclusive selection switches. Only one
switch can be active at any one time. The softkeys are used to
select the frequency coupling. The frequency coupling defines
which of the dependent parameters start frequency, center
frequency or span is to remain constant when the stop
frequency is changed.

STOP
MANUAL
The STOP MANUAL softkey activates the manual entry window for the stop
frequency.
The allowed range of values for the stop frequency is:
minspan ≤ f stop ≤ f max f stop stop frequency
minspan smallest selectable span (10Hz)
f max max. frequency

FIXED
If the START FIXED softkey is active, the start frequency remains constant
when the stop frequency is changed. The center frequency is adjusted to the
new frequency range. The START FIXED coupling is the default setting.

CENTER
FIXED
If the CENTER FIXED softkey is active, the center frequency remains
constant when the stop frequency is changed. The start frequency is adjusted
to the new frequency range.
IEC/IEEE-bus command :[SENSe:]FREQ:STOP:LINK CENTer
SPAN
FIXED
If the SPAN FIXED softkey is active, the span remains constant when the
stop frequency is changed. The start frequency is adjusted to the new
frequency range.

FREQ AXIS
LIN LOG
The FREQ AXIS LIN/LOG softkey switches between linear and logarithmic
scales on the frequency axis (see START key).
