Touch gestures in diagrams change measurement settings
When you change the display using touch gestures, the corresponding
measurement settings are adapted. This is different to selecting an area on
the screen in zoom mode, where merely the resolution of the displayed
trace points is changed temporarily (graphical zoom).
For example:
●
Dragging horizontally in a spectrum display changes the center fre-
quency.
●
Dragging vertically in a power vs frequency (spectrum) or power vs. time
display changes the reference level (for absolute scaling) or the min and
max power values (for relative scaling).
●
Dragging horizontally in a time domain display changes the trigger offset
value (if available, not in free run).
●
Spreading or pinching a spectrum display changes the center frequency
and span (horizontal) or reference level and range (vertical), or a combi-
nation of these settings (diagonal).
●
Spreading or pinching a time domain display changes the sweep time
and trigger offset (horizontal) or reference level position and range (ver-
tical), or a combination of these settings (diagonal).
You can prevent the firmware from changing specific settings using the
options in the context menu for the measurement zoom icon. By default, the
reference level is locked and thus not changed automatically due to touch
gestures.

ual).
