Pulse testing is a measurement technique that reduces the total energy consumption of a device. It avoids possible damage to small nanodevices by reducing Joule heating effects such as I2R and V2/R . The pulse test uses a sufficiently high power supply to apply a very short pulse to the device under test (DUT) to produce a high quality measurable signal and then remove the source.

Through pulse testing, engineers can obtain more device information and more accurately analyze and master the behavioral characteristics of the device. For example, pulse tester technology can be used to perform transient tests on nanodevices to determine their transfer function to analyze the characteristics of the material to be tested. Pulsed test measurements are also necessary for devices with constant temperature limits, such as SOI devices, FinFETs, and nanodevices, which avoid self-heating effects and prevent self-heating effects from masking the response characteristics of interest to researchers. Device engineers can also use pulse testing techniques to analyze charge trapping effects. The charge trapping effect reduces the drain current after the transistor is turned on. As the charge is gradually trapped into the gate dielectric, the threshold voltage of the transistor increases due to the built-in voltage of the gate capacitance ; thus the drain current is reduced.

Shanghai Haiyue Electronic Technology Co., Ltd. was established in 2006. Since its establishment, the company has been focusing on the R&D, production and sales of safety and electromagnetic compatibility test equipment. The company's main personnel have nearly 20 years of experience and rich practical experience. It has successfully provided a number of large-scale certification laboratories with the planning of test equipment and the supply of corresponding test equipment. The company produces hundreds of various types of safety equipment and test instruments, and undertakes non-standard custom test equipment.

The company has always adhered to the rigorous attitude, adhering to the "integrity as the cornerstone, providing professional technical services, perfect solutions, high-quality testing equipment" concept, constantly improve after-sales service, improve product quality, and strive to become the industry leader Our company's HY-1.2/50-12 pulse test generator generates high-energy (high-voltage, high-current) surges during operation. For your safety, please read this manual and use the device correctly. Please pay attention to the following points during use:

(1) Do not use this device when the hands are wet or the relative humidity exceeds 75% .

(2) Since a high voltage pulse is applied to the terminal ( Surge out ), if the wiring is changed, be sure to confirm that the high voltage power supply is off (the HVOFF light is on and the digital voltmeter is 0 ).

(3) Although the electric shock is rarely encountered when operating the device, for safety reasons, do not eat during operation to prevent accidental food blockage caused by electric shock.

(4) When using this equipment as an anti-interference test for the test article, be careful to ground the ground terminal of the device and the ground terminal of the test piece.

(5) With high voltage inside, do not disassemble or open the case to work.

2. Scope of application

The high-voltage pulse generator is strictly in accordance with GB4706.1/IEC60335-1 "General requirements for the safety of household and similar electrical appliances". The requirements of Chapters 14 , 19 and 29 of the standard are used to detect the ability of components to be subjected to transient overvoltage . And the clearance and creepage distance of the appliance.
