SIGNAL COLLECTION SYSTEM WITH FREQUENCY REDUCTION MODULE AND SIGNAL COLLECTION METHOD

摘要

An exemplary signal collection system includes a signal transmitting module, a computer, and a data collection card interconnecting the signal transmitting module and the computer. The signal transmitting module includes a signal source and a delay chip connected to the signal source. The delay chip receives a first path high-speed signal with a high frequency output from the signal source and transmits the first path high-speed signal as is to the data collection card in real time. The delay chip generates a second path high-speed signal by delaying the first path high-speed signal and transmits the second path high-speed signal to the data collection card. The data collection card reduces the frequencies of the high-speed signals transmitted from the delay chip and transmits the high-speed signals with reduced frequencies to the computer. A signal collection method based upon the signal collection system is also provided.
