• Alternating edges — Useful when you want to trigger on both edges of a clock
(for example, DDR signals).
• Either edge — Useful when you want to trigger on any activity of a selected
source.
Rising and Falling edge modes operate up to the bandwidth of the
oscilloscope. Other modes operate up to the bandwidth of the oscilloscope or
1 GHz, whichever is smaller.
The selected slope is displayed in the upper-right corner of the display.
Using Autoscale to
Set Up Edge
Triggers
The easiest way to set up an Edge trigger on a waveform is to use Autoscale.
Simply press the [Auto Scale] key and the oscilloscope will attempt to trigger on the
waveform using a simple Edge trigger type. See “Use Autoscale" on page 34.
NOTE
MegaZoom Technology Simplifies Triggering
With the built-in MegaZoom technology, you can simply Autoscale the waveforms, then stop
the oscilloscope to capture a waveform. You can then pan and zoom through the data using
the Horizontal and Vertical knobs to find a stable trigger point. Autoscale often produces a
triggered display.
