1MHz to 1000MHz RF Frequency Counter

PLJ-6LED-H is the high cost of six LED frequency display designed specifically for the HAM module, mainly for display devices such as transceiver frequency values can also be used in conventional frequency measurements. The module has a compact, reliable performance, visual effects, low cost and so on.


Main Product Details:


Master by the United States Microchip (Microchip) PIC16F648A as the core of 65MHz frequency counter.


Japan KDS frequency reference temperature-compensated voltage controlled crystal oscillator (± 2.5 ppm VC-TCXO)


Unique gate control and precise time algorithm (non-timer interrupt)


Gate (display refresh) time 0.64 seconds, real-time display frequency value.


Frequency measurement accuracy 10Hz / 100Hz (digital right one) is optional.


Dual IF design, IF value and plus / minus preset mode can be used alone, independently of each other.


Display driver with LED display special chip, high brightness digital tube, less foreign interference.


ARK six .56 inches using digital display, automatic blanking invalid zero, eight adjustable brightness.


Circuit is simple and reasonable structure, two-button control, simple operation.


The settings are automatically saved, boot directly invoked.
