Blue color 1MHz~1GHz 6 led RF Signal Frequency Counter Cymometer Tester

Description

Main features:
 1GHz frequency to Microchip, PIC16F648A as the core.
 frequency reference with temperature compensation type voltage controlled crystal oscillator (2.5 ppm VC-TCXO).
 adopts gate control mode and the accurate time algorithm is unique.
 gate (refresh) time of 0.64 seconds, real-time display of frequency.
The precision of frequency measurement by 10Hz/100Hz (the right one) optional.
 dual frequency design, intermediate frequency value and plus / minus mode can be preset, and do not influence each other.
 display driver using the LED chip digital tube display, high brightness, less external interference.
 adopts six 0.56 inch digital tube display, automatic blanking invalid zero, eight stage adjustable brightness.
 simple circuit, reasonable structure, double button control, simple operation.
 all settings are automatically saved, boot directly call.
