Glossary
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. The
logic scope displays one data point for every acquisition interval.
Active cursor
The cursor that moves when you turn the general purpose knob. It is
represented in the display by a solid line. The @ readout on the display
shows the absolute value of the active cursor.
Aliasing
A false representation of a signal due to insufficient sampling of high
frequencies or fast transitions. A condition that occurs when a logic scope
digitizes at an effective sampling rate that is too slow to reproduce the input
signal. The waveform displayed on the logic scope may have a lower
frequency than the actual input signal.
Amplitude
The High waveform value less the Low waveform value.
Analog Mode
A logic scope display mode that presents each waveform in a waveform
group as the analog of its input signal. Use Analog mode to measure the
actual response of a group of waveforms. Analog mode is the only group
display mode that can switched between a display of all the channels in a
group (Analog All) and display of a single channel in a group (Analog
Selected). (Also see BusForm Mode, Timing Diagram Mode, and OFF
Mode.)
AND
A logic (Boolean) function in which the output is true when and only when
all the inputs are true. On the logic scope, that is a trigger logic pattern and
state function.
Area
Measurement of the waveform area taken over the entire waveform or the
