1. A device for acquisition of analog test signals for acoustic diagnosis of a test object, comprising:

  • a. at least one sensor sensing analog test signals from the test object, the at least one sensor including at least one of a vibration sensor and a acceleration sensor;

    b. a standard computer having at least a first and second area with external interfaces to a data bus of the computer;

    c. at least one standard interface card coupled to the data bus in the first area over at least one of the external interfaces in the first area, the at least one standard interface card digitizing the analog test signals from the at least one sensor and inputting the digitized test signals into the computer;

    d. at least one switch generating a binary trigger signal, the binary trigger signal being input onto the data bus in the second area over at least one of the external interfaces; and

    e. an executive routine in the computer, the executive routine turning on and off the input of digitized test signals after analysis of an instantaneous status of the binary trigger signal.
