AUDIO SWEEPER 7116C
An automatic sweep signal generator is an instrument designed for detecting various electroacoustic components (Rattle & Buzz) as well as for their dynamic tests. It is suitable for use in the R&D department, quality control department, and production line of manufacturers of speakers, headphones, receivers, buzzers, and sirens, as well as for the inspection of incoming materials in factories that manufacture various electroacoustic products, such as audio factory, telephone factory, earphone factory, speaker factory, and computer multimedia factory, etc. With standard sine waves and low distortion, it is the most suitable for listening to the noise from speakers.
Product advantages
1)、A manual or automatic logarithmic sweep is possible. The start/stop sweep range can be arbitrarily set as required.
2）、The voltage value has rough and fine setting buttons. A voltmeter with a resolution up to 0.001 V works with the rough and fine volume adjustment buttons to easily adjust to the required voltage. It is especially easy to set the precise low voltage value required by the receiver and headset.
3）、The F0 value can be tested manually, and the frequency can be fine-tuned. The digital display frequency meter is supported by the frequency fine-tuning button, so the F0 value of the resonance frequency of the speaker can be accurately measured.
4）、 The button function is simple and clear, and non-professionals can also use it. Models with different output powers of 20 W, 60 W, and 100 W are available and equipped with triple short-circuit protection circuits, which can allow long-term output short circuits without damage to the instrument. Therefore, it can continuously operate without interruption.
