ThePLJ-096OLED-L1 is a cost-effective OLED frequency kijelző modul designed for continuous signal frequency measurement. Alkalmas a következőkhöz displaying frequency values in transceivers and other equipment, as well as for general frequency measurement applications.
Key Features
Compact size, aesthetically pleasing kijelző, and simple circuit design. Dual-button control for intuitive operation.
Core component: Dedicated SJ8K24P-T chip-based 100 MHz frequency counter.
RF signal input via IPEX connector with high measurement sensitivity and low operating current.
On-panel power electronic switch (can be disabled), ideal for battery-powered applications.
Frequency reference: KDS/EPSON brand temperature-compensated voltage-controlled crystal oscillator (VC-TCXO) (±2.5 ppm).
Unique gate control method and precise gate time algorithm (non-timer interrupt) for high measurement accuracy.
Gate (kijelző refresh) time: 0.1s / 1.0s, with real-time frequency kijelző.
Frequency measurement resolution: 10 Hz / 1 Hz (optional, with trailing digit blanking).
Dual intermediate frequency (IF) design. IF values and add/subtract modes can be preset independently.
UART serial output for measurement data, facilitating secondary development.
All settings automatically saved to EEPROM and loaded on power-up.
