The Autoset function examines all channels for signals and displays corresponding
waveforms. Autoset determines the trigger source according to the following
conditions.
 If multiply channels get signals, the oscilloscope will use the channel with
the lowest frequency signal as the trigger source.
 If no signals are found, the oscilloscope will use the lowest-numbered
channel displayed in Autoset as the trigger source.
 If no signals are found and no channels are displayed, the oscilloscope will
display and use Channel 1 as the trigger source.
Sine Wave:
When you use the Autoset function and the oscilloscope determines that the signal is
similar to a sine wave, the oscilloscope displays the following options.
Sine Wave Options
Details
Multi-cycle Sine
Display multiple cycles that have appropriate vertical and
horizontal scales.
Single-cycle Sine
Set the horizontal scale to display about one cycle of the
waveform.
FFT
Convert the input time-domain signal to its frequency
components and display the result as a graph of
frequency versus amplitude (spectrum). Since it is a math
calculation, see Section 5.3.1 Math FFT for more
information.
Undo Setup
Let the oscilloscope recall the previous setup.
