The Auto Scale function examines all channels for signals and displays corresponding waveform. Auto Scale 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 Auto Scale 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.
When you use the Auto Scale function and the oscilloscope determines that the signal is similar to a sine wave, the oscilloscope
displays the following options.
Wave Options
Details
Multi-Period
Display multiple periods that have appropriate vertical and horizontal scales.
Single-Period
Set the horizontal scale to display about one period of the waveform.
