1MHz-1.2GHz Digital LED Frequency Counter Tester Meter for Module Ham Radio

Description

Product Description
Features:
PLJ-0802 embedded intelligent frequency meter is a frequency measurement instrument designed for HAM. It is small and exquisite, easy to operate and reliable. It is mainly used for frequency display of DIY transceivers, and can also be used for conventional frequency measurement. The main features of this frequency meter are as follows:
High-performance 1.2GHz frequency meter with Microchip's 8-bit single-chip PIC16F648A as the core.
⊙ The built-in frequency reference uses a temperature-compensated voltage-controlled crystal oscillator (± 2.5 ppm VC-TCXO).
⊙ Dual IF design, IF value and plus / minus mode can be preset separately.
⊙ Adopt LCD0802 liquid crystal display, up to 7 digits can be displayed, the frequency value is invalid and zero blanking automatically.
⊙ Anti-reverse power design, low-power battery-powered solution.
⊙ Double button control, good man-machine interface.
The settings are automatically saved in the EEPROM and can be called directly at the next boot.
