This article will discuss the application and advantages of nanosecond pulse power supplies in high-precision measurement from a professional perspective.
I. Basic Characteristics of Nanosecond Pulse Power Supply
A nanosecond pulse power supply is a device that can generate pulsed current or voltage within an extremely short period (nanoseconds). Its characteristic is that the pulse width is extremely narrow, and both the rising edge and falling edge are very steep, allowing it to provide a large amount of energy in a very short time. In addition, the nanosecond pulse power supply also has the advantages of high repetition frequency, high stability, and high precision, making it widely applicable in high-precision measurements.
