?STEADY VOLTAGE?The machine offer ±24V for power supply for choosing alternating current 110V or 220V. because of adapting steady voltage, it can offer steady output within setting range in spite of alternating current unsteady. Adapt Smith Special integer circuit on square wave integer appliance and high speed rising and descending square wave will be produced. ?6 PHASES FREQUENCY RANGE?X1 shift: 0.2Hz-20Hz; X10 shift: 2Hz-200Hz; X100 shift: 20Hz-2KHz; X1K shift: 200Hz-20KHz; X10K shift: 2KHz-200KHz; X100K shift: 20KHz-2MHz. Attenuator: 20 decibel, 40 decibel and 60 decibel in series for chose. Output wave for choice: The machine will display the sine wave if press to; The machine will display the square wave if press to. ?MAIN FEATURES?Strongly steady electro-circuit; Digital display about frequency &operate conveniently; 6-phases from 0.2Hz-2MHz; Output for empty carry arrive at 5V, 600? carried will be higher than 2V(sine wave); Output voltage balance may be adjusted by 2 groups of attenuator every 20dB and 40dB, total 60dB or potentiometer in continuity; Sine wave of square wave may be chosen to output. ?PROFESSIONAL SIGNAL GENERATOR?Output pole is push-pull direct current amplifier and can offer low impedance output circuit within DC-1KHz. The output message will be regulated by te buffer of the machine at first and regulated attenuator has 0-60dB setting range on the 60? impedance. Output voltage balance may be adjusted by 2 absolute attenuator every 20dB and 40dB or in 60dB series on 600?loads. ?AMORTIZED AMPLIFIER?Amortized amplifier is a wo phase direct current amplifier, offer the output pole about low impedance. Because of using non-linearity hearing resistance on minus direction for turning wheel, our machine can do the sine wave shape steadily in no time with the lowest distortion.
