本文主要是介绍[ECE] P2.3Determine t_P_LH and t_P_HL from the oscilloscope,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!

The terms t_P_LH and t_P_HL​​ refer to the propagation delays associated with the low-to-high and high-to-low transitions in a digital signal. These delays are essential in digital systems and are measured with respect to the voltage levels.

(Low-to-High Propagation Delay):

  • This is the time it takes for a signal to transition from a low voltage level to a high voltage level.
  • It's measured as the time difference between the 50% voltage points on the rising edge of the input and output signals.

(High-to-Low Propagation Delay):

  • This is the time it takes for a signal to transition from a high voltage level to a low voltage level.
  • It's measured as the time difference between the 50% voltage points on the falling edge of the input and output signals.

Key point is to measure the time difference between the 50% voltage points on the rising edges of the input and output signals.

  1. Volts/Div (Volts per Division):

    • It represents the vertical scaling on the oscilloscope.
    • This value indicates the voltage range represented by each vertical division on the display.
    • For example, if the setting is 1 Volt/Div, each vertical division on the screen represents 1 volt.
  2. Sec/Div (Seconds per Division):

    • It represents the horizontal scaling on the oscilloscope.
    • This value indicates the time duration represented by each horizontal division on the display.
    • For example, if the setting is 1 Sec/Div, each horizontal division on the screen represents 1 second.
  1. Volts/Div(每格电压):

    • 它代表示示波器的垂直缩放。
    • 该数值表示屏幕上每个垂直刻度所代表的电压范围。
    • 例如,如果设置为1 Volt/Div,屏幕上每个垂直刻度代表1伏特。
  2. Sec/Div(每格秒):

    • 它代表示示波器的水平缩放。
    • 该数值表示屏幕上每个水平刻度所代表的时间跨度。
    • 例如,如果设置为1 Sec/Div,屏幕上每个水平刻度代表1秒

How to read the criterion?

  1. Ch1 2V:

    • It indicates Channel 1 (Ch1) on the oscilloscope.
    • The setting is at 2 volts per division (2V/Div).
    • This means that each vertical division on the display represents a voltage range of 2 volts.
  2. Ch2 2V 5ns:

    • It indicates Channel 2 (Ch2) on the oscilloscope.
    • The setting is at 2 volts per division (2V/Div) for the vertical axis.
    • The setting is at 5 nanoseconds per division (5ns/Div) for the horizontal axis.
    • This means that each vertical division represents a voltage range of 2 volts, and each horizontal division represents a time duration of 5 nanoseconds.

In Chinese (简体中文):

  1. Ch1 2V:

    • 表示示波器的第1通道(Ch1)。
    • 设置为每格电压为2伏特(2V/Div)。
    • 意味着屏幕上每个垂直刻度代表2伏特的电压范围。
  2. Ch2 2V 5ns:

    • 表示示波器的第2通道(Ch2)。
    • 设置为每格电压为2伏特(2V/Div)的垂直轴。
    • 设置为每格时间为5纳秒(5ns/Div)的水平轴。
    • 意味着每个垂直刻度代表2伏特的电压范围,每个水平刻度代表5纳秒的时间跨度。
