The frequency accuracy of a frequency counter is determined by:
- A the characteristics of the internal time-base generator
- B the size of the frequency counter
- C type of display used in the counter
- D the number of digits displayed
Correct answer: A — the characteristics of the internal time-base generator. From the official ISED question bank, verified word for word.
Why
The accuracy of a frequency counter depends entirely on the stability and precision of its internal time-base generator, which acts as the master clock for all measurements. The full explanation — and one for every question — is in Pro.
