Settings automatically saved to EEPROM; no need to reset upon power-up Product Specifications: Product Name: Frequency Display Module Operating Voltage: DC 4.5-9V (5V recommended) Operating Current: < 30mA (Test condition: DC 5V supply) Display: 0.96-inch OLED Gate Time: 0.1 / 1.0 seconds Measurement Accuracy: 10/1Hz Measurement Range: 1KHz-100MHz Input Impedance: High Impedance Time Base Stability: ±2.5ppm Measurement Data Output: UART Serial Port Output On-Board Interfaces: Signal Input, Power Interface Application Scenarios: Radio Frequency Display, Radio Frequency Measurement, Oscillator Circuit Frequency Measurement, Crystal Oscillator Frequency Screening, Embedded Applications, General Frequency Measurement Description: The PLJ-096OLED-L1 is a cost-effective OLED frequency display module designed for continuous signal frequency measurement. Primarily used for displaying frequency values in transceivers and similar devices, it also supports general-purpose frequency measurement. Its unique gate control method and precise gate timing algorithm (non-timed interrupt) ensure high measurement accuracy. Precautions: 1. Avoid exposing the device to high temperatures, humidity, dusty environments, and prevent severe vibration. 2. The clock reference was calibrated with GPSDO and sensitivity optimized before shipment. Do not adjust settings unless necessary. 3. The onboard signal input connector is fragile; handle plug insertion/removal gently. FAQ: 1. Does this module interfere with transceivers? Answer: Zero interference is impossible. Microcontrollers, crystal oscillators, etc., emit radiation, though at low intensity. Design measures mitigate this. Interference also depends on module placement relative to transceiver components and transceiver characteristics. If interference occurs, relocate the module or add shielding. 2. Why does the frequency display fluctuate? Answer: First, ensure the input signal quality (strength, stability, etc.) meets the module's minimum requirements (see technical specifications). Additionally, verify power supply quality—ripples should not be excessive. Alternatively, adjust the sensitivity trimming resistor to improve stability. 3. Why does the display fluctuate irregularly when no measurement signal is connected? Answer: First, check if the power supply ripple for this module is excessive. Then, inspect the module's surroundings for strong signal radiation.
