0.96-inch OLED Display RF Frequency Meter 2.7GHz/100MHz Signal Frequency Counter
The PLJ-096OLED-H1/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. It employs a unique gate control method and precise gate timing algorithm (non-timed interrupt) to achieve high measurement accuracy.
1. Compact and aesthetically pleasing design with dual-button operation and simplified circuitry for ease of use
2. Unique gate control algorithm and non-interrupt design enhance measurement accuracy
3. Dual independent intermediate frequency presets with simultaneous addition/subtraction modes without interference
4. Automatic settings save function enables immediate use upon startup without reconfiguration
5. Widely applicable for measuring requirements in radios, walkie-talkies, oscillation circuits, etc.

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 during factory calibration. Do not adjust settings unless necessary.
3. The onboard signal input connector is a fragile component; handle plug insertion/removal gently.
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 proximity to transceiver components and transceiver characteristics. If interference occurs, relocate the module or add shielding.
2. Why is the frequency display unstable?
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.
