Validation through Actual Measurement:
Equipment Connection: The signal source, the network cable under test (actual length 2 meters), and the oscilloscope were connected via adapters.
Waveform Capture: The oscilloscope automatically displayed the transmitted and reflected signals.
Time Difference Measurement: The cursor function was used to precisely measure the time interval between the edges of the two signals.
Automatic Calculation: By substituting the values into the formula (Length = Speed of Light × Velocity Factor × Time Difference / 2), the result was calculated as 1.98 meters. The error was extremely small, fully meeting the needs of daily engineering and experimental applications.
