Getting Started
16. Vertical
controls
The Vertical controls consist of:
• Analog channel on/off keys — Use these keys to switch a channel on or
off, or to access a channel's menu in the softkeys. There is one channel
on/off key for each analog channel.
• Vertical scale knob — There are knobs marked for each
channel. Use these knobs to change the vertical sensitivity (gain) of
each analog channel.
• Vertical position knobs — Use these knobs to change a channel's
vertical position on the display. There is one Vertical Position control for
each analog channel.
• [Label] key — Press this key to access the Label Menu, which lets you
enter labels to identify each trace on the oscilloscope display. See
Chapter 9 , “Labels,” starting on page 119.
For more information, see Chapter 3 , “Vertical Controls,” starting on page
63.
17. Analog channel
inputs
Attach oscilloscope probes or BNC cables to these BNC connectors.
In the InfiniiVision 2000 X-Series oscilloscopes, the analog channel inputs
have 1 M
Ω
impedance.
Also, there is no automatic probe detection, so you must properly set the
probe attenuation for accurate measurement results. See “To specify the
probe attenuation" on page 68.
18. Demo 2,
Ground, and
Demo 1
terminals
• Demo 2 terminal — This terminal outputs the Probe Comp signal which
helps you match a probe's input capacitance to the oscilloscope
channel to which it is connected. See “Compensate Passive
Probes" on page 32. With certain licensed features, the oscilloscope
can also output demo or training signals on this terminal.
• Ground terminal — Use the ground terminal for oscilloscope probes
connected to the Demo 1 or Demo 2 terminals.
• Demo 1 terminal — With certain licensed features, the oscilloscope can
output demo or training signals on this terminal.
