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 8 , “Labels,” starting on page 107.
For more information, see Chapter 3 , “Vertical Controls,” starting on
page 55.
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 60.
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 27. 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.
