2 If you want to return to the oscilloscope settings that existed before, press Undo 
Autoscale.
3 If you want to enable "fast debug" autoscaling, change the channels

These are the same softkeys that appear in the Autoscale Preferences menu. 
See Chapter 22, “Utility Settings,” starting on page 231.
If you see the waveform, but the square wave is not shaped correctly as shown 
above, perform the procedure "Compensate Passive Probes" on page 25.
If you do not see the waveform, make sure the probe is connected securely to the 
front panel channel input BNC and to the Demo/Probe Comp terminal.
Compensate Passive Probes
Each oscilloscope passive probe must be compensated to match the input 
characteristics of the oscilloscope channel to which it is connected. A poorly 
compensated probe can introduce significant measurement errors.
