Touch gestures in diagrams change measurement settings
When you change the display using touch gestures, the corresponding mea-
surement 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 frequency.
●
Dragging vertically in a power vs frequency (spectrum) or power vs. time dis-
play 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 combination 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 (vertical), 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.
