ZQ4100 Type Distortion Meter Calibration DeviceDetailed product description：

The BO-13B (ZQ4100) distortion meter calibration device is a standard distortion wave signal generator with wide frequency band and high accuracy.
The frequency range of the standard distortion wave output by the instrument is 5HzGG to 200kHz, with adjustable borders; The distortion range of the output is 0.01% to 100%, with a minimum adjustment interval of 0.01%. The basic error of the standard distortion wave output is 0.5%.
The instrument is mainly used to calibrate nonlinear distortion measurement instruments, including distortion indication errors, frequency scale errors, distortion introduced into the machine, basic and frequency additional errors of unbalanced voltmeters; It can also be used to schedule high fidelity amplifiers and other audio networks; The precise, wideband, and wide range voltage signal output by the instrument can also be used for a voltmeter.
The BO-13B distortion meter calibration device is an updated version of our old product, the BO-13B distortion meter calibration device. It is mainly designed with integrated circuits, and has high reliability, small instrument size, light weight, easy operation and use. Its main technical indicators are significantly improved compared to the BO-13B type, and it is suitable for use in metrology departments, laboratories, and factories.
