To set Autoscale preferences
1 Press [Utility] > Options > Preferences > Autoscale.
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 [Auto Scale], all channels that meet
the requirements of Autoscale will be displayed.
• Only Displayed Channels — The next time you press [Auto Scale], 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 [Auto
Scale].
• 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 [Auto Scale] key is pressed. This is the default mode.
• Preserve — to make the oscilloscope remain in the acquisition mode you
have chosen when the [Auto Scale] key is pressed.
Setting the Oscilloscope's Clock
The Clock Menu lets you set the current date and time of day (24-hour format).
This time/date stamp will appear on hardcopy prints and directory information on
the USB mass storage device.
