Introduction:
H1 is a cost-effective OLED frequency display module designed for continuous signal frequency measurement. It is primarily used for displaying frequency values in transceivers and other communication equipment, as well as for general frequency measurement applications.
Features:
1. Compact & User-Friendly: Small size, aesthetically pleasing display, simple circuit design, and dual-button control for intuitive operation.
2. High-Frequency Measurement: Core based on the dedicated SJ8K24P-T chip, supporting measurements up to 2.7 GHz.
3. High Sensitivity & Low Power: RF signal input via IPEX connector with high sensitivity and low operating current.
4.Power Management: On-board electronic power switch (can be disabled), ideal for battery-powered applications.
4. Precision Reference: Features a KDS/EPSON brand temperature-compensated voltage-controlled crystal oscillator (VC-TCXO) with ±2.5 ppm stability.
6. Advanced Algorithm: Unique gate control method and precise gate time calculation (non-timer interrupt) for high accuracy.
7. Configurable Display: Gate (display refresh) time: 0.64s / 1.0s, with real-time frequency value updates.
8. Resolution Options: Frequency measurement resolution: 100 Hz (0.64s gate) / 64 Hz (1.0s gate), with trailing digit blanking.
9. Dual IF Design: Two independent intermediate frequency (IF) settings. IF values and add/subtract modes can be preset separately without interference.
10. Data Output: UART serial output for measurement data, enabling secondary development.
11. Memory Storage: All settings automatically saved to EEPROM and loaded on power-up.
