Specification:
Features:
-
A 65MHz frequency meter based on for Microchip's PIC16F648A.
-
The frequency reference uses a temperature compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO).
-
Adopt unique gate control method and precise time algorithm (non-interruption mode).
-
The gate (display refresh) time is 0.1 second, and the frequency value is displayed in real time.
-
Frequency measurement accuracy 10Hz/100Hz (shift one bit to the right) is optional.
-
Double IF design, IF value and addition/subtraction mode can be preset separately without affecting each other.
-
The display driver adopts LED display special chip, the digital tube has high brightness and less external interference.
-
It adopts six-digit 0.56-inch digital tube display, invalid zero automatic blanking, and eight levels of brightness adjustable.
-
The circuit is simple, the structure is reasonable, double button control, and the operation is simple.
-
Each setting is automatically saved, and the power is on.
