AC coupling
A type of signal transmission that blocks the DC component of a signal but
uses the dynamic (AC) component. Useful for observing an AC signal that is
normally riding on a DC signal.
Accuracy
The closeness of the indicated value to the true value.
Acquisition
The process of sampling signals from input channels, digitizing the samples
into data points, and assembling the data points into a waveform record. The
waveform record is stored in memory. The trigger marks time zero in that
process.
Acquisition interval
The time duration of the waveform record divided by the record length.
Except in equivalent time, the oscilloscope acquires one data point for every
acquisition interval.
Aliasing
A false representation of a signal due to insufficient sampling of high
frequencies or fast transitions. A condition that occurs when a 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.
Amplitude
The High waveform value less the Low waveform value.
AND
A logic (Boolean) function in which the output is true only when all the
inputs are true. On the oscilloscope, that is a trigger logic pattern and state
function.
Area
Measurement of the waveform area taken over the entire waveform or the
gated region. Expressed in mixed amplitude and time units, such as
volt-seconds. Area above ground is positive; area below ground is negative.
Attenuation
The degree the amplitude of a signal is reduced when it passes through an
attenuating device such as a probe or attenuator. That is, the ratio of the input
measure to the output measure. For example, a 10X probe will attenuate, or
reduce, the input voltage of a signal by a factor of 10.
