To set AutoScale preferences

2 In the AutoScale Preferences Menu, you can:
• Press the Fast Debug softkey enable/disable this type of autoscale.
When fast debug is enabled, autoscale lets you make quick visual
comparisons to determine whether the signal being probed is a DC voltage,
ground, or an active AC signal.
Channel coupling is maintained to allow easy viewing of oscillating signals.
• Press the Channels softkey and turn the Entry knob to specify the channels to
be autoscaled:
• All Channels — The next time you press [AutoScale] , all channels that meet
the requirements of AutoScale will be displayed.
• Only Displayed Channels — The next time you press [AutoScale] , only the
channels that are turned on will be examined for signal activity. This is
useful if you only want to view specific active channels after pressing
[AutoScale] .
• Press the Acq Mode softkey and turn the Entry knob to select whether the
acquisition mode should be preserved during autoscale:
• Normal — to make the oscilloscope switch to Normal acquisition mode
whenever the [AutoScale] key is pressed. This is the default mode.
