1* PLJ-6LED-A Frequency Counter Frequency Display Component Measurement Module ~
Features:
*100% brand new and high quality
*Made of high quality material, durable and practical to use
* 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).
*Using a unique gate control method and precise time algorithm (non-interrupted method).
*The gate (display refresh) time is 0.1 seconds, and the frequency value is displayed in real time.
*The accuracy of frequency measurement is 10Hz/100Hz (shift one bit to the right) optional.
*Dual intermediate frequency design, intermediate frequency value and plus/minus mode can be preset separately, without affecting each other.
*The display driver adopts LED display special chip, and the digital tube has high brightness and little external interference.
*Using six-digit 0.56 inch digital tube display, invalid zero automatic blanking, eight-level brightness adjustable.
*Simple circuit, reasonable structure, double button control, simple operation.
*Various settings are automatically saved and directly recalled after power-on.
* IF setting
Dual intermediate frequency design, the minimum step of intermediate frequency adjustment is 100 Hz, the intermediate frequency range is 0 ~ 99.9999 MHz, and the intermediate frequency plus or minus intermediate frequency mode can be set.
* Frequency reference
Using a 5032 package 13.000MHz temperature compensated voltage controlled crystal oscillator (VC-TCXO), the frequency stability is ±2.5 ppm.
*Working voltage
DC input: DC 8V~15V (with power reverse polarity protection) or DC 5V (hardware setting required).
* Working current max 90 mA
*Display digits: six digits common anode LED display, the highest display is six digits.
