A zoom box lets you quickly draw a box around an area of interest in the Waveform or Zoom Overview. Drawing a box immediately
puts the oscilloscope into zoom mode. To draw a zoom box, tap the DRAW-A-BOX button (while in Zoom mode), then touch and drag
on the waveform to draw a box waveform. You can continue to draw zoom boxes until you single tap anywhere on the screen or open a
menu.
To toggle between Zoom mode, Visual Trigger mode, and Mask mode, double-tap the DRAW-A-BOX button and select one of the
three options. Search for the Visual Trigger and Mask Testing topics in the oscilloscope Help for more information.
5. The Zoom View shows the zoomed waveforms, as marked by the Zoom Box, in the Zoom Waveform Record View. Use pinch and/or
drag options in the zoom view to change the zoomed area of interest. Pinch, expand, and drag gestures in the Zoom View only change
zoom magnification settings and Zoom Box position.
6. Use the Zoom Title Bar controls to adjust the vertical and horizontal size of the zoom area. Click or tap the + or - buttons or use the A
and B multipurpose knobs.
In a waveform view, if both Cursor and Zoom are turned on, use the Zoom Box and Cursors button to change the multipurpose knob
functionality. Tap the Zoom Title Bar to assign the knobs to adjust the zoom or tap the Cursors button to assign knobs to adjust the
cursors.
Double tap the Horizontal Zoom Position or Horizontal Zoom Scale fields to enter a value using a numerical keypad.
To exit the zoom display mode, tap the Zoom icon in the corner of display or tap the X in the Zoom Title Bar.
Using the touch screen interface for common tasks
Use standard touch screen actions, similar to those found on smart phones and tablets, to interact with most screen objects. You can also
use a mouse to interact with the UI. The equivalent mouse operation is shown for each touch operation.
The oscilloscope has a user interface tutorial. Tap Help > User Interface Tutorial to quickly learn the fundamental touch operations.
