Creating Zooms
Any type of trace can be zoomed by creating a new zoom trace (Zn) following the procedures here. Zoom
traces open in the same grid, with the zoomed portion of the source trace highlighted.
Area around zoomed section shaded.
Quick Zoom
Use the front panel Zoom button to quickly create one zoom trace for each displayed channel trace. Quick
zooms are created at the same vertical scale as the source trace and 10:1 horizontal magnification.
To turn off the quick zooms, press the Zoom button again.
Manually Create Zoom
To manually create a zoom, touch-and-drag diagonally to draw a selection box
around any part of the source trace.
The zoom will resize the selected area to fit the full width of the grid. The degree
of vertical and horizontal magnification, therefore, depends on the size of the
rectangle that you draw.
Finally, you can create a Zoom math function. This method creates a new Fn
trace, rather than a new Zn trace, but it can be rescaled in the same manner. It is
a way to create more zooms than you have Zn slots available on your instrument.
Adjust Zoom Scale
The zoom's Horizontal units will differ from the signal timebase because the zoom is showing a calculated
scale, not a measured level. This allows you to adjust the zoom factor using the front panel knobs or the
zoom factor controls however you like without affecting the timebase (a characteristic shared with math
and memory traces).
Close Zoom
New zooms are turned on and visible by default. If the display becomes too crowded, you can close a
particular zoom and the zoom settings are saved in its Zn slot, ready to be turned on again when desired.
