Basic Operation 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. 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.
