The level of a video signal usually corresponds to the brightness, or luminance, of the part of the image being drawn onto a regular video screen at the same point in time. A waveform monitor can be used to display the overall brightness of a television picture, or it can zoom in to show one or two individual lines of the video signal.
A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronic stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that correspond to two logic states ("low state" and "high state", "0" and "1").
The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
The Software Communications Architecture (SCA) is an open architecture framework that defines a standard way for radios to instantiate, configure, and manage waveform applications running on their platform. The SCA separates waveform software from the underlying hardware platform, facilitating waveform software portability and re-use to avoid ...
A multiburst waveform is a useful test pattern used to quickly ascertain the frequency response of a video system. The name derives from the multiple bursts of sine wave in the active video section of the waveform which are generated with (usually) increasing frequency, but identical in amplitude.
A video vectorscope displaying color bars. The diagonal direction of the colorburst vector is indicative of a PAL signal. The graticule of an NTSC vectorscope. A PAL vectorscope displaying color bars. A vectorscope is a special type of oscilloscope used in both audio and video applications. [1]
A waveform viewer is a software tool for viewing the signal levels of either a digital or analog circuit design. [1] Waveform viewers comes in two varieties: simulation waveform viewers for displaying signal levels of simulated design models, and
PV-WAVE (Precision Visuals - Workstation Analysis and Visualization Environment) is an array oriented fourth-generation programming language used by engineers, scientists, researchers, business analysts and software developers to build and deploy visual data analysis applications.
