To capture a single-shot event
1 Connect the signal to the oscilloscope.
2 Press the Channel key (located on the plug-in). Set the channel Display to
on. Then, select the Scale and Offset settings to display the signal
vertically.
3 Press the Time base key. Then, select the Scale and Position settings to
display the signal horizontally.
4 Press theTriggered key. Then, Set up the trigger menu to best capture the
signal. Set the Sweep to triggered.
5 Press Acquisition. Then, set the Sampling mode to real time.
6 Press the Stop/Single key.
This stops the oscilloscope from acquiring any additional data.
7 Press the Clear display key.
This erases any previously acquired data from the display and resets any
measurement results.
8 Press the Stop/Single key again.
This rearms the trigger circuit. The next event that meets the trigger
criteria specified in step 4 is captured by the oscilloscope. If the channel
and time base controls are set correctly, the signal is displayed on the
screen and any measurement results are recalculated.
To capture additional data, press the Stop/Single key again. Depending on
your application, you can press the Clear display key between acquisitions,
or you can allow the display to build a waveform.
To allow the waveform to build on the display, set the display persistence to
a long time (several seconds or more) and do not press the Clear display
key between acquisitions.
