Product Description
7116C provides pure sine wave with very low total harmonic distortion. (approx. 0.1% THD ). The total harmonic distortion of 7116C consists of 2nd Harmonic component only and nearly without higher order harmonic components. So, 7116C is very suitable to test the sound quality ( spurious noise inspection ) of all kinds of loudspeaker, headphone, receivers, piezo, speakers system…etc.
The frequency produced by 7116C is more stable than the ordinary beat frequency oscillator produced. and the sine wave provided by 7116C is purer than the ordinary function generator. Therefore, 7116C has both advantages of low distortion and high stability. do not use the ordinary function generator to test the spurious noise ( rattle and buzz ) of loudspeaker, loudspeaker, receiver, etc.… Because user will easily neglect the prohibited spurious noise caused originally from the high order distortion component of the function generator.
1. Power: power switch & indicator 2. Fo: The lowest resonant frequency Fo test pushbutton. 3. Start: By depressing this button, The desired start frequency can be set by adjusting the coarse knob (5) and fine knob (6) of 〝 Start 〞. the start frequency can be set in the range of 20Hz to 20KHz. the frequency will be displayed on 〝 Frequency Counter (14) 〞in the front panel. 4. Stop: By depressing this pushbutton, The stop frequency can be set adjusting the stop knob (7). The stop frequency also can be set in the range of 20Hz to 20KHz and can be displayed on 〝 Frequency Counter (14) 〞in the panel.

5. Coarse ( Start ) : The coarse knob of start adjustment for setting the start frequency. Please depress the start pushbutton before adjusting the coarse knob. 6. Fine ( Start ): The fine knob of start adjustment for setting the start frequency. This knob is convenience for researching the lowest resonant frequency because the frequency variation is tiny. 7. Stop: The stop knob of stop adjustment for setting the stop frequency. Remember to set the stop frequency always higher than the start frequency. 8. Auto / Manu: When depressing the button, The output signal of 7116C will sweep forth and back automatically between the range set by the start adjustment knobs and stop adjustment knob. If button (3) or (4) is depressed, The 7116C will output a signal of constant frequency by adjusting start knobs or stop knob, And 7116C will be functioned as a manual sweep generator. 9. Sweep: Sweep time control knob with scale in second. Sweep time is continuously adjustable in the range of 0.3 sec. to 40 sec. 10. Coarse ( Volume ): For adjusting the output voltage in great variation. 11. Fine ( Volume ): For adjusting the output voltage in small variation. 12. Output: The output terminals to the tested item. 13. Output Voltage Meter: A digital autoranging R.M.S. voltage meter indicating the voltage from the output terminal. 14. Frequency: 4 digits display, 20Hz∼20KHz, Resolution: 1 Hz counter.
Frequency Range: Cover 20Hz to 20KHz in one range, ( usually under 15Hz and higher than 21KHz ). 2. Frequency Counter: 4 digits display, resolution 1Hz, accuracy ±1Hz. 3. Signal: Sine Wave, THD.<0.15% ( 1KHz, 10V ), THD. 0.1% typical. 4. Power Output: 7116C ( 20W ) 0- 12.6V 8 OHMS load. ( At rated line 0- 9.0V 4 OHMS load.
