1. Connect the signal generator to AC 220V, 50Hz power supply, press the power switch, the indicator light will light up, turn on the power, and the switch indicator light will display. Select the appropriate signal output form (square wave or sine wave).

2. Press the selection function switch of the desired waveform. When it is necessary to output a pulse wave, pull out the duty cycle adjustment switch and adjust the duty cycle to obtain a stable and clear waveform. At this time, the frequency is 1/10 of the original value. Press the duty cycle switch knob in the sine and triangle wave states. When a small signal output is required, press the attenuator to select the frequency range of the required signal, press the corresponding level switch, and adjust the trimmer appropriately. At this time, the data indicated by the trimmer is multiplied by the same level data to the actual output signal frequency. .

3. Adjust the power amplitude of the signal and appropriately select the attenuation level switch to obtain the signal with the required power. Adjust the amplitude knob to the required output amplitude. When the DC level is required, pull out the DC offset adjustment knob and adjust the DC level offset to the level value that needs to be set. In other states, press the DC offset adjustment knob and the DC level will be zero.

4. Distinguish the positive and negative signal output plugs from the output terminals.
