High-performance 1.2GHz frequency counter based on for Microchip’s 8-bit microcontroller PIC16F648A
The minimum step of intermediate frequency adjustable is 100Hz, the intermediate frequency range is 0~999.9999MHz, and it is set to plus or minus intermediate frequency mode
Built in frequency reference adopts temperature‑compensated voltage‑controlled crystaloscillator (±2.5 ppm VC‑TCXO)
Adopt dual intermediate frequency design, intermediate frequency value and plus/minus mode can be preset separately
LCD0802 LCD screen display, up to 7 digits can be displayed, and the frequency value of invalid zero is automatically blanked
