PLJ-6LED 6LED H RF Frequency Counter Tester Module 0.1MHz~65MHz (Backlit Font red)

Features:High Precision Frequency Measurement: It uses a temperature compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO) as the frequency reference and combines it with a unique accurate time algorithm. The frequency measurement precision is optional between 10Hz/100Hz, meeting high precision frequency measurement requirements.Real Time Display and Flexible Gating: With a gate (refresh) time of 0.1 seconds, it can display the frequency in real time. At the same time, it adopts the gate control mode to ensure measurement accuracy and real time performance.Dual Frequency Design and Preset Function: The dual frequency design allows for the preset of the intermediate frequency value and plus/minus mode, and they do not interfere with each other, meeting the frequency display and measurement needs in different scenarios.Excellent Display Effect: It uses an LED chip digital tube display, which has high brightness and strong resistance to external interference. It adopts six 0.56 inch digital tubes, automatically blanks invalid zeros, and has eight level adjustable brightness, providing a good visual effect.Simple Operation and Data Saving: The circuit is simple, the structure is reasonable, and it is controlled by double buttons, making the operation easy. All settings are automatically saved and can be directly called when booting up, which is very convenient to use.Specifications:Material: PCBSize: As picture showsDisplay Color: RedWorking voltage: DC 8V-15VWorking current: 90mA(max)Input impedance: High resistanceSensitivity: Better than 60mVPPGate time: 0.1secondDisplay digits: Six common anode LED display, the highest displays six digitsOnboard Interface: RF IN (Input): HX2.54-2P socketICSP (Programming Interface): 2.54-6P PinDC IN (Power Interface): HX2.54-2P socketNOTE: To ensure optimal performance and safety of this product, we recommend installation and use by professionals with relevant expertise.
