DC 8v~15v 6 Digit Blue LED Display RF Signal Frequency Counter 0.1mhz~65mhz NEW

Description: PLJ-6LED-A is a cost-effective six-digit LED frequency display module specially designed for forum HAM friends. It is mainly used to display the frequency value of transceivers and other equipment and can also be used for regular frequency measurement. This module has the characteristics of small and exquisite reliable performance good visual effect and low cost. Feature: ⊙A 65MHz frequency meter with Microchip s PIC16F648A as the core. ⊙The frequency reference adopts temperature-compensated voltage-controlled crystal oscillator (±2.5 ppm VC-TCXO). ⊙The gate control mode and the time algorithm adopted (non-interruption mode). ⊙The gate (display refresh) time is 0.1 seconds and the frequency value is displayed in real time. ⊙Frequency measurement accuracy is 10Hz/100Hz (one digit shift to the right) optional. ⊙Double IF design the IF value and the plus/minus mode can be preset independently without affecting each other. ⊙The display driver adopts LED display chip the digital tube has high brightness and less external interference. ⊙It adopts six-digit 0.56-inch digital tube display the invalid zero is automatically blanked and the eight-level brightness is adjustable. ⊙The circuit is simple the structure is reasonable the double button control the operation is simple. ⊙ All settings are automatically saved and can be called directly when power on. Technical Parameters: 1. Gate time 0.1 seconds 2. Measurement channel Input impedance: high impedance Measuring range: 0.1MHz~65MHz Measurement accuracy: 10 Hz Sensitivity: better than 60mVpp 3. IF setting Independent dual intermediate intermediate frequency design the minimum step of intermediate frequency adjustment is 100Hz the intermediate frequency range is 0~99.9999MHz and the mode of adding frequency or subtracting intermediate frequency can be set. 4. Frequency reference Using 5032 package 13.000MHz Temperature Compensated Voltage Controlled Crystal Oscillator (VC-TCXO) the frequency stability is ±2.5ppm. 5. Working voltage DC input: DC8V~15V (with power reverse polarity protection) or DC5V (hardware setting required). 6. Working current: Max 90mA 7. Display digits: Six-digit common anode LED display the highest display six digits. 8. Display brightness Eight-level LED brightness is adjustable and the factory setting is the highest brightness. 9. Physical dimensions: Length×width×height: 91mm×28mm×20mm 10.
