DF1316 series audio frequency sweep signal generator adopts the latest foreign electronic technology and novel voltage control RC oscillating circuit is a powerful instrument that can generate a pure sine wave signal. The output voltage and waveform of this series of instruments all frequencies are displayed with nixie tubes, and all working parameters are set with keys and potentiometers. With sweep range up to 1: More than 1000, high output power (up to 200W), low waveform distortion, etc. The power amplifier has power on delay output, over-temperature protection, short circuit protection, overload current limiting protection, excessive output amplitude protection, over-temperature display, and overload display.
This series of instruments is beautiful in appearance, compact in size, novel in structure, simple in operation, and extremely convenient in maintenance due to its modular design. It can be widely used in acoustics, vibration, and other aspects as a signal excitation source, especially suitable for the loudspeaker production lines as pure sound measurement
