The ZOOM softkey activates the zoom mode and opens a
sub-menu to define the zoom span.
Two frequency lines, which show and define the frequency
range to be zoomed, appear in the active measurement
window when the zoom mode is switched on. The default
setting is a zoom span of 10% to the left and 10% to the right
of the center frequency. The zoomed display is shown in the
second measurement window.
The settings for the second measurement window are taken
from the original window. The second measurement window
thus becomes the active measurement window and its
settings can now be changed.
If only one window is active when the zoom function is
selected, SPLIT SCREEN mode is automatically switched on.
The zoom span can be edited by using the softkeys of the
sub-menu to change the position of the frequency lines.
The softkey ZOOM OFF switches off the zoom.
MOVE ZOOM
WINDOW
The MOVE ZOOM WINDOW softkey shifts the whole zoom window. The
window can shifted until the upper frequency line reaches the stop frequency
or the lower frequency line reaches the start frequency of the original window.

MOVE ZOOM
START
The MOVE ZOOM START softkey shifts the lower frequency line. The start
frequency of the zoomed display can then be modified. The frequency line
can be shifted to the start frequency of the original window or to the upper
frequency line (= zero span).

:DISPlay[:WINDow]:TRACe:X[:SCALe]:ZOOM ON
:DISPlay[:WINDow]:TRACe:X:ZOOM:STARt 100MHz
MOVE ZOOM
STOP
The MOVE ZOOM STOP softkey shifts the upper frequency line. Thus, the
stop frequency of the zoomed display can be modified. The frequency line
can be shifted to the stop frequency of the original window or to the lower
frequency line (= zero span).
IEC/IEEE-bus commands
:DISPlay[:WINDow]:TRACe:X[:SCALe]:ZOOM ON
:DISPlay[:WINDow]:TRACe:X:ZOOM:STOP 200MHz
ZOOM
OFF
The ZOOM OFF softkey switches the zoom function off and then returns
control to the main menu.
The frequency lines indicating the zoom range are deleted, SPLIT SCREEN
mode remains active, the settings of both measurement windows are
retained and the coupling of the two measurement windows is cancelled.
