Automatically Displaying a Waveform
The oscilloscope has an Autoscale feature that automatically sets up the
oscilloscope to best display the input waveform. Using Autoscale requires
waveforms with a frequency greater than or equal to 50 Hz and a duty cycle
greater than 1%.
When you press the Autoscale button, the oscilloscope turns on and scales all
channels that have waveforms applied, and selects a time base range based on
the trigger source. The trigger source selected is the lowest numbered channel
that has a waveform applied. The 3000 Series Oscilloscopes are two channel
oscilloscopes with an external trigger input.
