Digital Channels

Any digital channel with an active signal will be displayed. Any digital channels

without active signals will be turned off.
• To undo the effects of AutoScale, press the

Undo AutoScale

softkey before

pressing any other key.

This is useful if you have unintentionally pressed the

[AutoScale]

key or do not like

the settings AutoScale has selected. This will return the oscilloscope to its

previous settings. See also:

“How AutoScale Works"

on page 31.

To set the instrument to the factory-default configuration, press the

[Default Setup]

key.

Interpreting the digital waveform display

The following figure shows a typical display with digital channels.
