Description

Function:

1 This is a 65MHz frequency meter based on Microchip PIC16F648A2. Frequency standard uses temperature compensated voltage controlled crystal oscillator (±2.5ppm VC‑TCXO)
3 Using unique gate control system and precise time algorithms (non-interrupt mode)
4 Frequency measurement accuracy is optional 10Hz/100Hz (1 bit right shift).
5 Gate (display update) time is 0.1 second, real-time display frequency value
6 Dual intermediate frequency design, intermediate frequency value, positive / negative mode can be individually preset and will not affect each other.
7 The display driver uses a dedicated LED display chip, and the digital tube has high brightness and less external interference. Adopts 6-digit 0.56-inch digital tube display, zero invalid automatic blanking, 8-level brightness adjustable
9 Simple circuitry with reasonable structure and double button operation for easy operation.
10 Different settings can be automatically saved and calling directly after power on
