Analog switches which have great influence on the resolution of a whole acquisition system, are widely used in analog signal acquisition system of spacecraft and civil. Signal crosstalk is one of most difficult problems in Multi-input analog switches. A data acquisition system on spacecraft has many channels, large amount of data and high precision requirements. In order to improve the sampling-rate and reduce the noise of a data acquisition system, it is especially important to effectively reduce the crosstalk of multi-input analog switch. This paper introduces the types and solutions of signal crosstalk of analog switch in a vibration acquisition system. They effectively reduced signal crosstalk of the vibration acquisition system and improved the sampling-rate of the vibration acquisition system. |
