Programmable oscillators refer to circuit components which are capable of delivering precisely controlled signals with designated frequencies and duty cycles. SGR-8002DC-PCM, with its adjustable duty cycle to 99.9%, is one of the most popular programmable oscillators in the market. This oscillator boasts its classical design, low cost, and easy installation. Although this component is mainly used in the manufacturing of telecom, consumer electronics and industrial components, its applications extend to almost all types of electronic instruments, high-precision equipment, power amplifiers and so on.

In terms of working principle, SGR-8002DC-PCM utilizes a positive voltage and a negative voltage such as GND to control its on-off cycles and drive the ringing current to a desired frequency. To generate a signal, the oscillator requires the injection of a current I_IN which is determined by the voltage V_IN, according to Ohm\'s law.

The current source serves as the signal source, firstly controlling the voltage V_IN. The voltage V_IN is then applied onto the basis of the oscillator\'s transistors and bring about the oscillation. Ultimately, the current I_IN passes through the collector of the circuit to the signal source, producing the desired ringing current.The device also uses an external resistor as a control element, granting the user the ability to control the operational frequency and duty cycle easily.

To sum up, SGR-8002DC-PCM is a highly popular programmable oscillator owing to its versatile application field, relatively low cost and easy setup. With its adjustable duty cycle and working principle, the oscillator is capable of providing users with a wide range of performance to suit their specific needs.
