HDO6000 High Definition Oscilloscope
New zooms are turned on and visible by default. However, you can turn off a particular zoom if the display
becomes too crowded, and the zoom settings are saved in its location, ready to be turned on again when
desired.
The zoom's Vertical and Horizontal units will differ from the source trace, as seen from a comparison of
the trace descriptor boxes, because the zoom is showing a scale, not a measured level.
Channel descriptor box and its Zoom descriptor box.
You can further adjust these settings using the Front Panel knobs, or by changing the settings on the
Zoom dialog. Touch the zoom descriptor box to activate it, then touch it again to display the Zx tab.
Because it is a calculated and not a sampled trace, you can adjust the zoom's Horizontal Scale without
changing the oscilloscope's Timebase (a characteristic shared with math and memory traces).
Turn off Zoom
Turn off a zoom trace the same as you would any other trace:
l Deselect the Trace On checkbox on the Zoom dialog.
l Touch-and-hold (right-click) the descriptor box until the pop-up menu opens, then choose Off.
Quick Zoom
Use the Front Panel Zoom button to quickly create one zoom trace for each displayed channel trace.
NOTE: Quick zooms are created at the same vertical scale as the source trace and 10x horizontal
magnification.
To turn off the quick zooms, press the Zoom button again.
Multi-Zoom
The Multi-Zoom feature creates time-locked zoom traces for only the waveforms that you choose to
include. The zooms are of the same X-axis section of each waveform. As you scroll through a waveform,
all included zooms scroll in unison.
Zoom Controls
Once the zoom trace has been created, adjust its Vertical and Horizontal Scale to further "zoom" in or out.
You can do this by activating the zoom trace and using the Front Panel Vertical and Horizontal knobs, or
by modifying settings on the Zoom dialog.
