To make a single acquisition

When you press the [Single] key it illuminates in yellow and the oscilloscope starts the
acquisition system, searching for the trigger condition. When the trigger condition is met,
the captured waveform is displayed, the [Single] key is extinguished and the [Run/Stop]
key illuminates in red.
• Use the [Single] key to view single-shot events without subsequent waveform data
overwriting the display.
Use [Single] when you want the maximum sample rate and the maximum memory depth
for pan and zoom. (See
1 Set the trigger mode to Normal (see
for instructions).
This keeps the oscilloscope from automatically triggering immediately.
2 If you are triggering on analog channel events, turn the Trigger Level knob to the
trigger threshold to a level that your waveform will cross.
3 To begin a single acquisition, press the [Single] key.
When you press [Single], the display is cleared, the trigger circuitry is armed, the
[Single] key is illuminated yellow, and the oscilloscope will wait until a trigger
condition occurs before it displays a waveform.
When the oscilloscope triggers, the single acquisition is displayed and the
oscilloscope is stopped (the [Run/Stop] key is illuminated in red).
4 To acquire another waveform, press [Single] again.
Auto Single
Auto-trigger will generate a trigger for you if one is not found in the predetermined time
(about 40 ms) after you press [Single]. If you want to make a single acquisition and you
are not particularly interested in triggering the acquisition (for example, if you are probing
a DC level), set the trigger mode to Auto (see
trigger condition occurs, it will be used; if a trigger doesn't happen, an untriggered
acquisition will be taken.
