General type audio signal analysis appearance

The utility model discloses a general type audio signal analysis appearance, including a plurality of audio output unit and a plurality of audio input unit, a plurality of audio output unit and a plurality of audio input unit link to each other with the computer through the bus respectively, audio output unit, audio input unit connection have power management?module, and power management?module connects the display. This equipment range of application is extensive, can select through the impedance, adapts to different investigated subjects to impedance match's requirement, has improved the load bearing capability of equipment, have audio output synchronizing function, audio input synchronizing function, the time delay condition that can the test signal transmission course, the noise signal that the audio output signal of equipment can superpose the different grade type can test the working property of equipment under test under the noise condition. Thereby realize that the price / performance ratio is higher to all kinds of audio signal parameter index's measurement.
