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 28.
Pulse Width Trigger
Pulse Width (glitch) triggering sets the oscilloscope to trigger on a positive or
negative pulse of a specified width. If you want to trigger on a specific timeout
value, use Pattern trigger (see
"Pattern Trigger" on page 141).
1 Open the Trigger dialog box by selecting the trigger badge or by choosing
Trigger > Setup... from the main menu.
2 In the Trigger Type drop-down list, select Pulse Width.
3 Select the Source channel.
The channel you select is shown in the trigger badge next to the polarity
symbol.
The source can be any analog or digital channel available on your oscilloscope.
4 Adjust the trigger level:
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.
