Abstract:

The number and type of sensor is becoming more and more on modern vibration tests. According to the actual test, 64-channel high-speed synchronization acquisition system has been developed, which can match charge-output sensor and voltage-output sensor. This system has two application modes, the real-time data acquisition and the transient acquisition. It has several advanced functions, such as program controlled amplifier, program controlled filter and auto zero. The whole system adopts master-slave structural design method, which has the following advantages, such as simple structure, low cost and high reliability etc.

Key words: vibration testing, synchronous acquisition, 64-channel
