Primarily used for displaying frequency values in transceivers and similar equipment, it is also suitable for general frequency measurement. It employs a unique gate control method and precise gate timing algorithm (non-timed interrupt) to achieve high measurement accuracy. Precautions: 1. Avoid exposing the instrument to high temperatures, humidity, or dusty environments, and prevent severe vibration. 2. The clock reference was calibrated using GPSDO and sensitivity optimized during factory calibration. Do not adjust these settings unless necessary. 3. The onboard signal input connector is a fragile component. Handle it gently when inserting or removing plugs. Package include: Module x1 Signal cable x1 Power cable x1 label:yes
