Crystal Oscillator Frequency Counter Tester Meter, DIY 1Hz-50MHz Frequency Indicator Crystal Oscillator Tester Module Kit with 5 Digits Digital Tube Display Red

This is a frequency meter based on PIC microcontroller, with crystal vibration measurement function and programmable frequency settings.

With five- digit digital tube display, the measurement data display is intuitive and convenient.

All of them use direct-plug components.

The circuit is simple, easy to make, easy to install and debug.

The measuring frequency range of this DIY frequency meter is 1Hz-50MHz, which can measure the oscillation frequency of most commonly used crystal oscillators.

Five-bit resolution (e.g., 0.0050kHz, 4.5765MHz, 11.059MHz) supports automatic range conversion.

Programmable add and subtract frequency settings for measuring equipment such as radio transceivers.
