1-1200mhz 1MHz-12GHz RF Frequency Counter Tester Digital PLJ-0802-E DC 9-12V LCD Meter Product Features: Compact shape Easy to use Simple operation Stable performance Good effect Product Description: PLJ-0802 Embedded Intelligent Frequency Meter is a frequency measurement instrument designed for HAM. It is small and exquisite, easy to operate, reliable, mainly used for DIY transceiver for frequency value display, can also be used for conventional frequency measurement. The main features of this frequency meter are as follows: A high-performance 1.2 GHz frequency meter with 8-bit microcontroller PIC16F648A as the core. The built-in frequency reference is a temperature compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO). Dual IF design with separate presets for IF value and add/drop modes. LCD0802 liquid crystal display with 7-digit numeric display and automatic blanking for invalid zero frequency value. Anti-reverse power supply design, low power consumption battery power supply program. Dual-key control with good human-machine interface. The settings are automatically saved in EEPROM and can be directly recalled next time the power is turned on. Technical parameters: 1. Gate time: 0.64 seconds 2.
