Frequency counter 100 kHz - 65 MHz

PLJ - 6 leds - A is designed for the HAM friends of cost-effective six LED display module, frequency is mainly used for transceiver equipment such as frequency values show, also can be used in the conventional frequency measurement.


This module is compact, reliable performance, good visual effect, low cost, etc.


Main features:


1 PIC16F628A Microchip company as the core of 65 MHZ frequency meter.


Type 2 frequency reference with temperature compensation voltage controlled crystal oscillator (+ / - 2.5 PPM VC - TCXO).


3 adopt unique gate control mode and precision of algorithm.

4 gate time of 0.1 seconds (display refresh), real-time display frequency values.

5 10 hz / 100 hz frequency measurement precision (right one) is optional.

6 double medium frequency design, intermediate frequency value and add/subtract mode can be preset alone, each other.

7 shows driver using special chip LED display, digital tube high brightness, less foreign interference.

8 using six 0.56 -inch digital tube display, automatic blanking invalid zero, changing the brightness is adjustable.

9 simple circuit, reasonable structure, double button control, simple operation.

Each set automatically saved 10, boot direct call.
