Trigger Slope –
The slope that a trigger source signal must reach before
the trigger circuit initiates a sweep.
Vertical Resolution (Analog-to-Digital Converter) –
An indication of
how precisely an analog-to-digital converter (ADC) in a digital oscilloscope
can convert input voltages into digital values, measured in bits.
Calculation techniques, such as hi res acquisition mode, can improve
the effective resolution.
Vertical Sensitivity –
An indication of how much the vertical amplifier can
amplify a weak signal – usually measured in millivolts (mV) per division.
Volt –
The unit of electric potential difference.
Voltage –
The difference in electric potential, expressed in volts, between
two points.
Wave –
The generic term for a pattern that repeats over time. Common
types include: sine, square, rectangular, saw-tooth, triangle, step, pulse,
periodic, non-periodic, synchronous, asynchronous.
Waveform –
A graphic representation of a voltage varying over time.
Waveform Capture Rate –
Refers to how quickly an oscilloscope acquires
waveforms, expressed as waveforms per second (wfms/s).
Waveform Point –
A digital value that represents the voltage of a signal
at a specific point in time. Waveform points are calculated from sample
points and stored in memory.
Writing Speed –
The ability of an analog oscilloscope to provide a visible
trace of the movement of a signal from one point to another. This ability is
restrictive for low-repetition signals that have fast-moving details, such as
digital logic signals.
Z Axis –
The display attribute on an oscilloscope that shows brightness
variations as the trace is formed.
