Mini 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 -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, boot directly call. Gate time:0.64 sec Measuring range: 1 MHz to 1.2 GHz Measurement accuracy: 100Hz Channel Sensitivity: (HM8134-2 data) Test Frequency (MHz): 5 10 30 60 100 150 200 300 450 Sensitivity (mV RMS): 35 20 10 3 3 4 8 15 12 Test Frequency (MHz): 500 550 600 700 800 900 1000 1100 1200 Sensitivity (mV RMS): 14 30 65 80 80 35 175 270 310 Operating voltage:DC input: DC 9V - 12V (reverse polarity protection with power supply) Operating current:Enable backlight: less than equal 55 mA Display digits:The highest 8 digits are displayed IF settings:IF adjustable minimum step of 100 Hz, the range of 0 to 999.9999 MHz, can be set to increase the IF or reduced IF mode. Frequency reference:The 13000-MHz temperature-compensated voltage-controlled crystal oscillator (-TCXO) in a 5032 package has a frequency stability of 2.5 ppm. RF INPUT (measurement signal input): XH2.54-2P square mouth socket ICSP INPUT (MCU programming interface): XH2.54-6P pin POWER INPUT (power connector): XH2.54-2P square port socket name:Frequency Meter Colour:As Shown Material:PCB+Plastic+Metal Package Contents: 1 x PLJ-0802-E frequency counter meter with cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
