2020 wholesale price Signal Source 20hz-20khz 40w 110v - RK1316BL/ RK1316D/ RK1316E/ RK1316G/ Audio Signal Generator – Meiruike

Product Introduction
RK1316 Series  Audio Signal Generator Adopts Advanced Voltage Controlled Oscillation Circuit To Produce Stable And Low Distortion Sine Wave Signal. Digital Display Of Output Amplitude And Frequency Is Adopted. The Frequency Sweep Range Can Be More Than 1:1000. The Starting Point And End Point Of Frequency Sweep Can Be Set Arbitrarily. It Has The Functions Of Power On Delay Output And Short Circuit Protection. At The Same Time, It Can Also Test The Positive And Negative Polarity Of Loudspeakers, Earphones And Moving Coil Receivers Of Any Type, Size And Impedance.
Application Area
The Instrument Can Not Only Produce Audio Signals For Audio Audiometry, But Also Accurately And Quickly Identify The Positive (Negative) Polarity Of The Loudspeaker And The Pure Tone Index Of The Loudspeaker. Simple Operation, Widely Used In Acoustics, Telecommunications And Other Aspects, Especially Suitable For Speaker Production And Speaker Manufacturers.
