[Auto Scale] When you press the [AutoScale] key, the oscilloscope will quickly
key determine which channels have activity, and it will turn these channels
on and scale them to display the input signals. See
page 26.
Additional The additional waveform controls consist of:
waveform • [Math] key — provides access to math (add, subtract, etc.) waveform
controls functions. See
• [Ref] key — provides access to reference waveform functions.
Reference waveforms are saved waveforms that can be displayed and
compared against other analog channel or math waveforms. See
Chapter
• [Digital] key — Press this key to turn the digital channels on or off
(the arrow to the left will illuminate).
When the arrow to the left of the [Digital] key is illuminated, the
upper multiplexed knob selects (and highlights in red) individual
digital channels, and the lower multiplexed knob positions the
selected digital channel.
If a trace is repositioned over an existing trace the indicator at the left
edge of the trace will change from Dn designation (where n is a one
digit channel number from 0 to 7) to D*. The "*" indicates that two
channels are overlaid.
You can rotate the upper knob to select an overlaid channel, then
rotate the lower knob to position it just as you would any other
channel.
For more information on digital channels see
Channels," starting on page 81.
• [Serial] key — This key is not currently used with the 2000 X-Series
oscilloscopes.
• Multiplexed scale knob — This scale knob is used with Math, Ref, or
Digital waveforms, whichever has the illuminated arrow to the left.
For math and reference waveforms, the scale knob acts like an analog
channel vertical scale knob.
• Multiplexed position knob — This position knob is used with Math,
Ref, or Digital waveforms, whichever has the illuminated arrow to the
left. For math and reference waveforms, the position knob acts like an
analog channel vertical position knob.
