MCU is the abbreviation for Microcontroller Unit, commonly known as a microcontroller. It appropriately reduces the frequency and specifications of CPUs, integrating memory, counters, USB, A/D converters, UART, PLC, DMA, and even LCD driver circuits onto a single chip, forming a chip-level computer. This allows for different combinations of control for various applications, such as … Read more
How do we calculate the positive duty cycle for such a narrow pulse on the screen? We set the horizontal time base to 200us/div, allowing us to observe its two cycles. Since the pulse is too narrow, using traditional manual measurement with cursors is not the best option. What methods can the ZDS2022 provide? The … Read more
