Glossary
AC Coupling
A mode that blocks the DC component of a signal but passes the
dynamic (AC) component of the signal. Useful for observing an
AC signal that is normally riding on a DC signal.
Acquisition
The process of sampling signals from input channels, digitizing
the samples, processing the results into data points, and
assembling the data points into a waveform record. The
waveform record is stored in memory.
Aliasing
A false representation of a signal due to insufficient sampling of
high frequencies or fast transitions. A condition that occurs
when an oscilloscope digitizes at an effective sampling rate that
is too slow to reproduce the input signal. The waveform
displayed on the oscilloscope may have a lower frequency than
the actual input signal.
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 trigger event.
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.
