select Autocale...). See
"To set Autoscale preferences" on page 280.
If you see the waveform, but the square wave is not shaped correctly as shown

"Compensate Passive Probes" on page 29.
If you do not see the waveform, make sure the probe is connected securely to the
front panel channel input BNC and to the Probe Comp terminal.
How Autoscale Works
Autoscale analyzes any waveforms present at each channel and at the external
trigger input. This includes the digital channels, if connected.
