Abstract

Laying the foundation on the virtual instrument technology

combining the microelectronics technology and the computer technology

which can take samples continuously is composed from a PXI-E5622 ADC

a virtex5 FPGA and a computer.The test result shows that it can record wireless signals under high sample rate.Owing to the function of demodulation

its easy to get to know the quality of the signal and to judge the working state of the signal source.Surely will simplify the wireless testing process and save manual labor when used in the test of wireless communication equipments.
