| 摘要 |
It is proposed a data acquisition apparatus (1), comprising:
- a receiving antenna (63), receiving a radio communication signal including synchronization information representative of a remote reference clock signal;
- a local clock circuit (8), delivering a local clock signal (CLK);
- a gauging circuit (61), measuring a frequency drift and a phase error of the local clock signal (CLK) in view of the synchronization information;
- an analog-to-digital converter (3), providing a series of digital sampled and dated data according to the local clock signal (CLK); and
- a correcting circuit (4), correcting the series of digital sampled and dated data based at least on the measured frequency drift and phase error. |
