A board level test system for the multi-pole array acoustic logging tool

To improve examining and repairing efficiency of Acoustic Multi-Pole Logging Tool (MPAL) in the process of industrialization, a kind of board level test system is introduced to test the MPAL analog signal receiving and acquisition circuit and the transmitting control circuit. Also, the basic principles of analog signal´s consistency test and the design of the test system interface circuit are introduced. Experimental results show that the board level test system can measure the performance and consistency of the analog signal receiving and acquisition circuit and the transmitting control circuit accurately. It has a guiding significance for the process of adjusting circuit parameters. In other words, it is a kind of effective monitoring equipment during the industrialization and debugging of acoustic logging tools.
