Looking for Gw Instek Gad Ic? GW Instek GAD 201 G Automatic Distortion Meter is available at Zbotic with fast shipping across India.
GW Instek GAD 201 G Automatic Distortion Meter
The GW Instek GAD 201 G Automatic Distortion Meter is specifically designed for measuring total harmonic distortion (THD) and AC voltage within the audio frequency range of 20 to 20kHz. This device displays both frequency and voltage values simultaneously on dual meters, with automatic switching of measurement range over the full scale. Convenient shortcut keys are available for commonly used frequencies such as 400Hz, 1kHz, and 10kHz.
The GAD-201G features an output terminal that provides basic waveform (X) and harmonic distortion (Y) to external monitoring devices. It maintains residual distortion, including hum and noise, at a minimum level of 0.03%, making it exceptionally well-suited for high-class audio applications.

Frequently Asked Questions
What frequency ranges can the GAD 201 G measure?
The GAD 201 G covers a continuous frequency range of 20 Hz to 20 kHz in three bands, plus three fixed-frequency spots at 400 Hz, 1 kHz and 10 kHz via shortcut keys.
How accurate is its distortion measurement?
It measures total harmonic distortion from 0.1% up to 100% across seven selectable ranges, enabling precise evaluation of even very low distortion levels.
Can I monitor distortion output externally?
Yes. The meter provides an X terminal for the basic waveform and a Y terminal for the harmonic distortion component, allowing connection to oscilloscopes or chart recorders.
