Features   Frequency from 10Hz ~ 1MHz   0.02% Low Sine Wave Distortion (GAG-810 Only)   6 Steps Output Attenuator   EXT SYNC Function The GAG-809/810 provide a convenient solution for low frequency (< 1MHz) signal generation, specifically for audio bandwidth. Intuitive and simple panel interface provides quick frequency and amplitude adjustment, with dial/key shortcuts to different ranges. Square wave generation covers digital application in addition to the traditional analog using sine waves. Distortion is kept at minimum level, especially at the audible frequency range: 0.02% or less distortion factor for 500Hz~20kHz. The external synchronization signal input helps collaborate with other measurement devices.   SINE WAVE CHARACTERISTIC  Frequency Range 10Hz ~ 1MHz, 5 Ranges Frequency Indicator Dial Scale Frequency Accuracy ±(5% + 1Hz) (at 10, 100 position, Expect x 1 Range) Output Voltage 5 Vrms (600Ω load) Frequency Response 10Hz ~ 1MHz ± 0.5dB(at 600Ω load)Reference Frequency (1kHz) Distortion Factor 500Hz ~ 20kHz: ≦0.02% (GAG-809 : ≦0.1%)100Hz ~ 100kHz: ≦0.05% (GAG-809 : ≦0.3%)(x 10 range for 100Hz, x 1k range for 100kHz)50Hz ~ 200kHz: ≦0.3%20Hz ~ 500kHz: ≦0.5%10Hz ~ 1MHz: ≦1.5% SQUARE WAVE Output Voltage ≧10Vp-p (no load) Overshoot ≦2% (at 1kHz, max output) Rise & Fall Time
