Which of the following factors most affects the accuracy of a frequency counter?
Pick an answer to check it.
Answer: B. Time base accuracy
A frequency counter compares the input to its internal time base, so the counter is only as accurate as that time base. An error in the reference shows up directly in every reading.
Tip: Counter accuracy = time base accuracy.
