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 [AutoScale] key and the oscilloscope will attempt to trigger on the
waveform using a simple Edge trigger type. See “Use Auto Scale" on page 30.
NOTE
Alternating edge mode is useful when you want to trigger on both edges of a clock (for
example, DDR signals).
Either edge mode is useful when you want to trigger on any activity of a selected source.
All modes operate up to the bandwidth of the oscilloscope except Either edge mode, which
has a limitation. Either edge mode will trigger on Constant Wave signals up to 100 MHz, but
can trigger on isolated pulses down to 1/(2*oscilloscope's bandwidth).
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.
