3 MHz Function Generator

3 MHz analog function generator is a piece of electronic test equipment used to generate different types of electrical waveforms. Some of the most common waveforms produced by function signal generator are the sine, square, triangular and sawtooth shapes. Signal generator is widely used in development, test and repairing electronic equipment.

1. 3 MHz analog function generator adopts precise current source circuit which makes the output signal has high accuracy over the whole frequency band.
2. Signal generator is composed of operational amplifier and discrete component. It features simple structure, low cost and high reliability.
3. The computer case of 3 MHz analog function generator is beautifully designed and is control by full board. It is more comfortable and convenient to operate.

1. 3 MHz analog function generator should be equipped with suitable line voltage.
2. To avoid electrical shock, the protective grounding conductor of power cord should be connected to ground.

1. To maintain good ventilation, regular cleaning should be carried out.
2. Do not spray cleaner directly onto the instrument when cleaning it. Please use a soft cloth with mild detergent and water instead.
