\u25a0 TH1312 Series Audio Sweep Signal Generator3 3\/4-bit LCD display, sine wave output, small distortion, good stability, the frequency range covers the entire audio range. The frequency range covers the entire audio range. It can be manually adjusted, or logarithmically swept, and the starting point and end point of the frequency sweep and the sweep time can be set according to the requirements. The product has protection measures such as switching delay, over-current protection, short circuit protection, etc. It allows the output to be short-circuited for a long time, which provides convenience and protection for users. There are good load adjustment rate and amplitude-frequency flatness, three different output power models can be selected. It can be widely used as a signal excitation source in acoustics, vibration, telecommunication, etc. It is especially suitable for pure tone checking of loudspeaker units and loudspeaker systems (speakers).<\/p>","protected":false},"excerpt":{"rendered":"
