GAD-201G Automatic Distortion Meter

The GW Instek GAD-201G distortion meter is aimed at total harmonic distortion (THD) and AC voltage measurement at audio frequency range, from 20 to 20kHz. The GW Instek GAD-201G frequency and voltage values are displayed simultaneously on dual meters, with the measurement range automatically switching over full scale.

Shortcut keys are provided on the GW Instek GAD-201G for the more commonly used 400Hz, 1kHz, and 10kHz measurements. Output terminal feeds basic waveform (X) and harmonic distortion (Y) to external monitoring device. Residual distortion, including hum and noise, is kept at a minimum level of 0.03%, making the GW Instek GAD-201G ideal for high-class audio application.
