Distortion standard verification device
Product Introduction
The distortion standard verification device is a new type of fully automatic distortion measurement standard instrument developed by our company, Beijing Kaihong Electronic Instrument Co., Ltd., and the National Institute of Metrology of China to meet the development needs of distortion measurement. This instrument has the advantages of wide frequency band, wide range, multi-function, programmability, and high accuracy. It features reliable performance stability, easy operation, small size, and light weight. It can be used as a new measurement standard for verifying various general distortion meters, ultra-low distortion meters, and audio analyzers, suitable for use by metrology departments, laboratories, and factories.DS-1C is a precision standard distortion wave signal generator with an output frequency range from10Hz to200KHz. This standard has fourteen point frequencies in the10Hz to200KHz band, with a distortion range output from0.003% to100%. It can be operated manually or automatically. (Note:DS-1B is semi-automatic, whileDS-1C is fully automatic)
