1MHz-1.2GHz RF Frequency Counter Tester PLJ-0802-E Digital LCD screen display Meter Ham Radio DC 9-12V

PLJ-0802 Embedded intelligent frequency meter designed specifically for the HAM frequency measurement instruments. Its small and exquisite, simple, reliable, mainly for DIY transceiver for frequency value display can also be used for conventional frequency measurement. Micro chip's 8-bit microcontroller PIC16F648A as the core of the high-performance 1.2GHz frequency meter. Built-in frequency reference using temperature compensated voltage-controlled crystal oscillator (± 2.5 ppm VC-TCXO). Dual IF design, IF and add / subtract mode can be individually preset. LCD0802 LCD screen display, up to 7 digits can be displayed, the frequency value is invalid zero automatic blanking. Anti-power reverse design, low-power battery-powered programs. Double-button control, good man-machine interface. The settings are automatically saved, the next boot directly call. Technical Parameters: Gate time:0.64 sec Measuring range: 1 MHz to 1.2 GHz Measurement accuracy: ± 100Hz Channel Sensitivity: (HM8134-2
