The burst generator is from the circuit, such as from the switching transient process (cutting off the inductive load, bouncing off the relay contact, etc.). The burst generator is from the circuit, such as from the switching transient process (cutting off the inductive load, bouncing off the relay contact, etc.), which will usually interfere with other electrical and electronic equipment in the same circuit. This kind of interference is characterized by high amplitude, short rise time, high repetition rate and low energy. The narrow pulses appearing in groups can charge the junction capacitance of semiconductor devices, which may cause circuit or equipment errors when accumulated to a certain extent. The impulse generator determines a common reproducible evaluation basis for evaluating the ܫperformance of power supply ports, signal, control and grounding ports of electrical and electronic equipment when disturbed by electrical fast transient pulse groups

The burst generator is suitable for the occasion of electrical fast transient burst immunity test. It has good transient pulse waveform, high pulse repetition rate (up to 2MHz), stable performance, convenient operation, and fully conforms to the latest IEC standard iec61000-4-4, European electrical standard (en61000-4-4), and national standard (gb/t17626.4), It is an ideal interference source for electromagnetic compatibility test. It adopts 7-inch color touch screen for display and control, which is intelligent and efficient The user can edit the test program, and the instrument automatically completes the test according to the predetermined program. The test voltage, phase, cꦉycle, number of pulses, frequency, automatic cruise setting and automatic detection are convenient for finding the failure sensitive points of the tested samples. The pulse group generator meets the requirements of iec61000-4-4 and gb/ t17626.4 standards It is specially designed according to the characteristics and requirements of electrical and electronic equipment for electrical fast transient burst test, and meets the waveform requirements of 1K Ω load at the same time LCD intelligent control, using program-controlled high-voltage power supply, strong stability, built-in international standard grade parameters, small size, convenient operation
