1. A 65MHz frequency meter based on for Microchip's PIC16F648A.
2. The frequency reference uses a temperature compensated voltage controlled crystal oscillator (±2.5 ppm VC-TCXO).
3. Adopt unique gate control method and time algorithm (non-interruption mode).
4. The gate (display refresh) time is 0.1 second, and the frequency value is displayed in real time.
5. Frequency measurement accuracy 10Hz/100Hz ( one bit to the right) is optional.
