Introduction
The USB-9001 Multifunction Audio Test Set is a professional electro-acoustic test and audio analysis instrument. The USB-9001 incorporates the function of a polarity analyzer audio analyzer, signal generator, scanner, and multimeter. All this allows the USB-9001 to perform general performance testing solutions. You can use the USB-9001 to test earphone, microphone, artificial mouth, artificial ear and other electro-acoustic products.
The combination of powerful USB-9001, flexible analysis software AudioExpress, and high-precision USB data acquisition hardware meets various testing needs. An IEPE signal conditioner in the analog input channel provides constant current excitation and decouples the input bias voltage, and thus the USB-9001 can connect directly to two artificial ears or microphones. The specially added digital I/O channel controls cylinder switch conveniently.
The USB-9001 reduces electro-acoustic testing time and cost, and improve production efficiency greatly.
