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.
Square Wave or Pulse:
When you use the Autoset function and the oscilloscope determines that the signal is similar to a
square wave or pulse, the oscilloscope displays the following options.
Square Wave Options Details
Multi-cycle Square
Display multiple cycles that have appropriate vertical and
horizontal scales.
Single-cycle Square Set the horizontal scale to display about one cycle of the waveform.
