PLJ8LEDR Digital RF Frequency Meter Broad frequency range for versatile testing: 1 MHz to 2.4 GHz. This single meter covers common RF bands, reducing the need for multiple instruments. Automatic channel selection for convenience: The meter automatically selects the appropriate channel ( or low) based on the input signal frequency. This speeds up setup and measurement. Manual channel selection for higher frequencies: Manual channel selection is required for frequencies above 60 MHz, giving you control when precise configuration is needed. Ultracompact and portable design: Dimensions are 5 x 25.5 x 21.5 mm, making it easy to carry for field work or travel. Practical and reliable performance: Designed for straightforward frequency measurement across a wide range with a compact form factor suitable for onthego use. Use scenarios Field service and installation: verify transmitter outputs and RF signals on site to ensure correct operation. Wireless network maintenance: monitor RF activity in the 1 MHz to 2.4 GHz range to identify interference and confirm channel usage. Prototyping and onthego testing: carry in a toolkit to test RF modules and experiments while traveling.
