1Hz to 100KHz in five-decade ranges selected by rotary switch named as frequency Multiplier. Sine Triangular and Square waveforms selected by push switch with LED indication. The output signal is 0-3.5 V RMS (10V peak to peak) open circuit continuously control with an uncalibrated amplitude control knob. Mains rocker switch with indicator Light. Signal Generator is versatile for general laboratory use; the output signal is adjustable with the combination of Freq. multiplier and set frequency dial with a low level of distortion. Output Voltage is continuously variable with selector range 1V and 10V. There is two pair of output safety sockets. One for CRO output (experiment for amplification, filter, etc.) and another pair of sockets to speaker to drive a speaker and to demonstrate the audio signal frequency range 20Hz to 20KHz without BMC cable.
