Overshoot is the distortion that follows a major transition the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude. In clock recovery applications it is called timing jitter. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals.
drawBars (peaks: number Number < Array >, channelIndex: number, start: number, end: number) Draw a waveform with bars. destroy () This is called when wavesurfer is destroyed.
Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Create the wrapper element, style it and set up the events for interaction. Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. This is usually the bandwidth in which almost all of the power of a signal is contained. Tasks that are marked with start are in theory possible.Channel Bandwidth is the bandwidth over which power is measured.
Reduce amount of spelling mistakes in readme. Typings: PropTypes vs Flow vs TypeScript. Easy plugin add and remove after mount*. You can use onMount to instantly clear artificial markers. Workaround is also presented there (and in demo link). #2417: markers drag handlers not initialized with empty markers array in initial config. Try to not hard-bind redux-state with wavesurfer-react too tight or use an instance of wavesurfer to operate regions. Issues with regions synchronization when using redux and Region component. Can be used inside any custom component you will create and render within the borders of WaveSurfer component. Is used inside Region component to get wavesurfer instance. That is provided by the package or any other component, that is rendered inside WaveSurfer component,īut for the latter task you will have to get region instance first. Is used inside Region component to subscribe to region related events.Ĭan be used by developers, if they wanna to, inside a HOC-like component over Region component You can use it standalone to create you own (more specific) wavesurfer component that will handle more than a component that is provided out-of-the-box. #Wavesurfer custom style update
It also handles a task of creating and destroying wavesurfer plugins, after plugins prop update detection. This hook is used inside WaveSurfer and its purpose is to create wavesurfer instance and return it. Package provides the following set of hooks:
Rest passed props are used as marker's data Hooks
onDrop is emitted when element is released after drag. onDrag is emitted when drag operation is started. onClick is emitted when marker is clicked. We have decades of expertise in LECROY Calibration and can possibly repair the LECROY WAVESURFER 104XS-A 4 Ch 1 GHz WaveSurfer Digital Oscilloscope. LECROY WAVESURFER 104XS-A Calibration Price 185.00. MarkerĬan be used to imperatively control markers.įor now, only time is updatable and is watched for further updates, that are coming from outside of component. A calibration by Custom-Cal is performed by engineers with extensive OEM experience. Rest given props are passed as region's data into wavesurfer. 
onUpdateEnd - is called when dragging or resizing are finished. onUpdate - is called on each region's options update. onRemove - is called just before region remove. onOut - is called when playback leaves a region. onIn - is called when playback enters a region. onDoubleClick - is called on double click. onClick - is called on a mouse click on a region. onLeave - is called when moused leaves a region. onOver - is called when mouse enters a region. If region component did not find appropriate region, then it creates a region itself. On mount, it will try to find region with the same region identifier and then attaches itself to it. If region is already present of WaveForm it creation will be avoided and existing instance is used. It can be used to imperatively control regions, appearing on WaveForm if you're using RegionsPlugin. Think of it as a some kind of helper component. It accepts all options, passed into WaveSurfer.create, but except plugins. It has only one argument - WaveSurfer instance. It is a function, that is called after WaveSurfer instance has been mounted. Otherwise added to wavesurfer plugins list and immediately initialized. If plugin was disabled (it's not enlisted in plugins prop) it will be destroyed, The plugins prop is watched inside WaveSurfer.
