To display a signal automatically
The oscilloscope has an Autoscale feature that automatically sets up the
oscilloscope to best display the input signal. Using Autoscale requires signals
with a frequency greater than or equal to 50 Hz and a duty cycle greater than
1%.
When you press the Autoscale key, the oscilloscope turns on and scales all
channels that have signals applied, and it selects a time base range based on
the trigger source. The trigger source selected is the highest numbered input
that has a signal applied. (If a signal is connected to the external trigger
input on the HP 54600B and HP 54603B, then it is selected as the trigger
source.)
