| () |
| Abstract: |
| The principle and method of channel cross -correlation is analyzed, cross correlation function of the advanced dual - channel vector signal analyzer and the method of measuring the time delay of digital modulated signal via the function are introduced. The validity of the method is demonstrated through tests. |
| Key words: dual channel vector signal analyzer FFT channel cross correlation sampling rate |
