Which of the following is good practice when using an oscilloscope probe?
Pick an answer to check it.
Answer: A. Minimize the length of the probe's ground connection
A long probe ground lead adds inductance that causes ringing and distortion, especially on fast signals. Keeping the ground connection short gives a cleaner, more accurate trace.
Tip: Short ground lead, clean trace.
