{"product_id":"audio-sweeper-model-7116c-audio-frequency-sweeper","title":"AUDIO SWEEPER MODEL-7116C Audio frequency sweeper","description":"\u003cp\u003e7116C provides pure sine wave with very low total harmonic distortion. (approx. 0.1%\u003cbr\u003eTHD ). The total harmonic distortion of 7116C consists of 2nd Harmonic component only\u003cbr\u003eand nearly without higher order harmonic components. So, 7116C is very suitable to test\u003cbr\u003ethe sound quality ( spurious noise inspection ) of all kinds of loudspeaker, headphone,\u003cbr\u003ereceivers, piezo, speakers system…etc.\u003cbr\u003eThe frequency produced by 7116C is more stable than the ordinary beat frequency\u003cbr\u003eoscillator produced. and the sine wave provided by 7116C is purer than the ordinary\u003cbr\u003efunction generator. Therefore, 7116C has both advantages of low distortion and high\u003cbr\u003estability. do not use the ordinary function generator to test the spurious noise ( rattle\u003cbr\u003eand buzz ) of loudspeaker, loudspeaker, receiver, etc.… Because user will easily neglect\u003cbr\u003ethe prohibited spurious noise caused originally from the high order distortion component\u003cbr\u003eof the function generator.\u003cbr\u003e1. Power: power switch \u0026amp; indicator\u003cbr\u003e2. Fo: The lowest resonant frequency Fo test pushbutton.\u003cbr\u003e3. Start: By depressing this button, The desired start frequency can be set by adjusting\u003cbr\u003ethe coarse knob (5) and fine knob (6) of 〝 Start 〞. the start frequency can\u003cbr\u003ebe set in the range of 20Hz to 20KHz. the frequency will be displayed on\u003cbr\u003e〝 Frequency Counter (14) 〞in the front panel.\u003cbr\u003e4. Stop: By depressing this pushbutton, The stop frequency can be set adjusting the\u003cbr\u003estop knob (7). The stop frequency also can be set in the range of 20Hz to\u003cbr\u003e20KHz and can be displayed on 〝 Frequency Counter (14) 〞in the panel. \u003c\/p\u003e\n\u003cp\u003e5. Coarse ( Start ) : The coarse knob of start adjustment for setting the start frequency.\u003cbr\u003ePlease depress the start pushbutton before adjusting the coarse\u003cbr\u003eknob.\u003cbr\u003e6. Fine ( Start ): The fine knob of start adjustment for setting the start frequency.\u003cbr\u003eThis knob is convenience for researching the lowest resonant\u003cbr\u003efrequency because the frequency variation is tiny.\u003cbr\u003e7. Stop: The stop knob of stop adjustment for setting the stop frequency.\u003cbr\u003eRemember to set the stop frequency always higher than the start\u003cbr\u003efrequency.\u003cbr\u003e8. Auto \/ Manu: When depressing the button, The output signal of 7116C will\u003cbr\u003esweep forth and back automatically between the range set by the\u003cbr\u003estart adjustment knobs and stop adjustment knob. If button (3) or\u003cbr\u003e(4) is depressed, The 7116C will output a signal of constant\u003cbr\u003efrequency by adjusting start knobs or stop knob, And 7116C will\u003cbr\u003ebe functioned as a manual sweep generator.\u003cbr\u003e9. Sweep: Sweep time control knob with scale in second. Sweep time is\u003cbr\u003econtinuously adjustable in the range of 0.3 sec. to 40 sec.\u003cbr\u003e10. Coarse ( Volume ): For adjusting the output voltage in great variation.\u003cbr\u003e11. Fine ( Volume ): For adjusting the output voltage in small variation.\u003cbr\u003e12. Output: The output terminals to the tested item.\u003cbr\u003e13. Output Voltage Meter: A digital autoranging R.M.S. voltage meter indicating the\u003cbr\u003evoltage from the output terminal.\u003cbr\u003e14. Frequency: 4 digits display, 20Hz∼20KHz, Resolution: 1 Hz counter. \u003c\/p\u003e","brand":"TSD Electronic Store","offers":[{"title":"Default Title","offer_id":53278806606167,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/9389\/0135\/files\/Sweeper7116C.jpg?v=1775814979","url":"https:\/\/www.tsdwelltest.com\/products\/audio-sweeper-model-7116c-audio-frequency-sweeper","provider":"TSD Welltest Solution","version":"1.0","type":"link"}
