Instek GAG-810 Audio Generator

The Instek GAG-810 is a precision audio generator that produces sine and square waveforms across a 10 Hz to 1 MHz frequency range. Engineered for audio equipment testing and troubleshooting, it delivers stable output into standard 600 Ω loads with excellent low-distortion performance and flexible attenuation control.
