| Abstract: | For the measurement of the current limitations of the audio sweep signal, using NI PXI -5124 data acquisition card, In LabVIEW2012 development environment, an audio sweep signal tester is developed based on virtual instrument tech- nology, a direct measurement of the audio sweep signal is achieved. Development process is introduced and the basic proce- dure is given. It is confirm that the instrument is functioning properly ,the measurement results are accurated through the sys- tem test. A new idea for the measurement and calibration of audio sweep signal generator is provided. |
