Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
Auto Distortion Tester, Main Specifications: 20Hz ~ 20kHz
The GAD-201G Distortion Tester is used for harmonic distortion (THD) and AC voltage measurements in the audio range from 20 Hz to 20 kHz.Frequency and voltage values are displayed simultaneously on the instrument and can be switched automatically over the full scale range.The Shortcut key is used to measure the universal 400 Hz, 1 kHz and 10 kHz frequency points. The output terminals output the fundamental waveform (X) and harmonic distortion (Y) to an external monitoring device. Spurious distortion, including hum and noise, are controlled to a very low level of only 0.03%, making the GAD-201G available for advanced audio applications.
