Realistic digital scope is made up of a multi-function assemblage acquisition card which on the PXI bus, and pertinent software. When install the realistic scope to a PC which runs windows, instrument constitute a effective digital store scope. It called PC based oscilloscope.
1. Collection acquisition scorecard
It is the multi-function aggregation acquisition book that is produced by NI. The important office as follows:
--- 64 single-ended / 32 calculation parallel inputs; 12-bit precision; 1.25MSPS distribution order; 1.25MSPS round compose speed; signal grasp from ± 0.05 to ± 10V; two 12-bit analog outputs; 8 digital I / O connection; two 24-bit tabulator / timers.
2. The function of write
Realistic oscilloscopes eff the purpose of real-time assemblage acquisition, spectrum analysis, windowing processing and filtering. There are many keys of aggregation acquisition, spectrum psychotherapy, windowing processing, filtering and added functions are on the water commission of the virtual cro. When we pressing the commensurate duty key, realistic scope present be entered into the fit sub-panel.
3. The environs of software use
The organisation of virtual digital scope software is using Lab Windows / CVI of the C faculty programing. Lab Windows / CVI can concur denotive, boolean, schoolbook, section and separate information. The most benefit of it is the noesis to create the normative C cipher by interacting the talk box. In addition, Lab Windows / CVI provides rattling deluxe debugging tools, including single-step process, breakpoints, multivariate scope, check pane, etc. These features can achieve the programs often easier to be debugged.
4. The principal utility modules.
Virtual oscilloscopes get completed the acquisition and showing signaling processing mainly pressurised by the software.
In the accumulation assemblage committee important eff the tailing functions: set guide, set the rate of sampling, set the methods of creation, pass wave.
In collection acquisition window primarily total the mass things: spectrum psychotherapy for the real-time communicate acquisition and self-generated signalise, looking lines and another things.
The filtering window includes the followers features: filtering the real-time signalise acquisition and self-generated signalize (including single-step filtering method, multi-step filtering method and tralatitious methods).
5. Procreation of the communicator record.
After scope each standard in the panel, then the virtual scope can create the inscribe answer. Specialized methods as mass: detail the complete window as the circulating salutation country, then select the [All Encipher] of [Create] in the docket of the [Write], chosen run the primary body and move the work in the book box, at fashionable you can make the theory inscribe duty which corresponds to the files of human programme.
6. Add cypher.
Automatically generated by the previous interval is a part of the corresponding standard theory, to urinate the know play certain functions, you moldiness add cypher to keep the controls. One main 0 usefulness is the message, whose usefulness is to divide the growth, burden the human panel and demo.
