Attenuation
The degree the amplitude of a signal is reduced when it passes
through an attenuating device such as a probe or attenuator (the
ratio of the input measure to the output measure). For example,
a 10X probe attenuates, or reduces, the input voltage of a signal
by a factor of 10.
Auto Trigger Mode
A trigger mode that causes the oscilloscope to automatically
acquire if it does not detect a triggerable event.
Autorange
A DMM feature that automatically sets the range to the
optimum setting to measure an input signal. Also, an oscillo-
scope feature that automatically produces a stable waveform of
usable size. In both cases, autorange continues to change the
instrument settings to track additional signal changes.
Average Acquisition Mode
A mode in which the oscilloscope acquires and displays a
waveform that is the averaged result of several acquisitions.
This reduces the apparent noise. The oscilloscope acquires data
as in the sample mode and then averages it according to a
specified number of averages.
Backlight
The illumination behind the liquid-crystal display.
Bezel Buttons
The row of buttons below the display that selects items in the
menus.
