This text introduces to use the LabVIEW language to design the virtual digital oscillograph. The usage PCI-6024 card comes to reads the exterior inputs.
This text designs of the conjecture numeral collect the LabVIEW7.0 of the adoption N I company of the system system virtual instrument software terrace, collecting what card use is a voice card. The system of collecting channel can connect an external signal source to read an external signal, can also connect the computer sound card, sound card collection.This system main function is to pass to collect 1 to imitate signal as to it's carry on analysis, and complete to save and read of operation.Pass virtual instrument calculator with standardized virtual instrument hardware to combine to get up, to test the technical application contain very great exaltation
