Descriere PLJ-8LED-R Digital Cymometer Meter Tester 0.1MHZ-2.4GHz Digital RF Frequency Meter LED Display 8-Bit Display

1. High-Precision Frequency Measurement: The RF Frequency Counter, powered by Microchip's PIC16F648A, provides accurate frequency measurement to 2.4 GHz. It utilizes a temperature-compensated voltage-controlled crystal oscillator (2.5 ppm VC-TCXO) as its frequency reference, ensuring reliable and precise measurements.
2. Unique Gate Control and Algorithm: Featuring a unique gate control method and precise algorithm (non-timed interrupt mode), this frequency counter offers flexible gate (display refresh) times of 0.01s/0.1s/1.0s for optimal measurement accuracy. The real- frequency value is displayed instantly.
3. Versatile Channel Options: The RF Frequency Counter supports three measurement channels: low-pass channel, high-pass channel, and auto channel. It features a single-ended input design, allowing you to select the appropriate channel based your specific frequency measurement needs.
4. Dual Intermediate Frequency Design: With its dual intermediate frequency design, this frequency counter enables independent presetting of intermediate frequency values and addition/subtraction modes. It offers enhanced flexibility and customization options for advanced frequency measurements.
5. User-Friendly Interface and Settings: The RF Frequency Counter utilizes an eight-digit 0.56-inch high-brightness LED display with adjustable brightness (eight levels). It automatically hides invalid zeros, and you can choose to enable optional filters for displaying invalid frequency values. The circuit design is concise and well-structured, and the counter is controlled by two easy-to-use buttons.
