The Structure Of Online Oscilloscope

The Structure Of Online Oscilloscope

Virtual digital oscilloscope consist of a multi-function data buy card which on your PXI bus, and right software. When deploy the virtual oscilloscope to a PC which carries on windows, will be tantamount to a powerful digital memory space oscilloscope. It called PC based oscilloscope.
1. Facts acquisition card
It will be the multi-function data acquisition cartomancy that is produced by NI. The main function as accepts:
--- 64 single-ended / 24 differential analog inputs; 12-bit detail; 1.25MSPS sampling quote; 1.25MSPS disk produce speed; input start from ?0.05 to ?10V; only two 12-bit analog outputs; Nine digital I And O line; two 24-bit counter / electronic timers.

2. The function of instrument
Virtual oscilloscopes include the function of real-time data pay for, spectrum analysis, windowing digesting and filtering. There are a number keys of data obtain, spectrum analysis, windowing making, filtering and other performs are on the main solar panel of the virtual oscilloscope. When we finally press the corresponding operate key, virtual oscilloscope could be entered into the appropriate sub-panel.

About three. The environment of program development
The design of virtual digital oscilloscope software is using Lab Windows Or CVI of the C vocabulary programming. Lab Home's windows / CVI can support number, boolean, text, strings together with other data. The most benefit from it is the ability to generate the standard C passcode by interacting the actual dialog box. Aside from that, Lab Windows Versus CVI provides very rich debugging gear, including single-step execution, breakpoints, changeable view, watch time frame, etc. These features can certainly make the programs much better to be debugged.

4. The principal function modules.
Devoted oscilloscopes have completed the acquisition and then display signal digesting mainly controlled through software.
In the data files collection panel main have the following attributes: set channel, set in place the frequency of tasting, set the methods in production, display waveform.
