• Automatic set
Auto set is one of the advantages digital oscilloscopes have. When you push the Auto
button, the oscilloscope will identify the type of waveform (sine or square wave) and
adjust controls according to input signals so that it can accurately display the wave-
form of the input signal.
The Auto function examines all
channels for signals and displays
corresponding waveforms.
Auto determines the trigger
source according to the following
conditions :
If multiply channels get signals,
the oscilloscope will use the
channel with the lowest frequen-
cy signal as the trigger source.
If no signals are found, the oscil-
loscope 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.
