Frecventmetru digital 1,2Ghz LCD nou !

1. High-performance 1.2GHz frequency counter based on for Microchip's 8-bit microcontroller PIC16F648A
2. The minimum step of intermediate frequency adjustable is 100Hz, the intermediate frequency range is 0-999.9999MHz, and it is set to plus or minus intermediate frequency mode
3. Built in frequency reference adopts temperature compensated voltage controlled crystaloscillator (+-2.5 ppm VC TCXO)
4. Adopt dual intermediate frequency design, intermediate frequency value and plus minus mode can be preset separately
5. LCD0802 LCD screen display, up to 7 digits can be displayed, and the frequency value of invalid zero is automatically blanked
6. Anti reverse power supply design, provide low power battery powered solution
7. Come with double button control, which possess good man machine interface
8. Various settings are automatically saved in EEPROM and directly recalled after power on

Specification:

Item Type: Frequency Measurement Module
Material: PCB
Uses: Mainly used for DIY transceivers for frequency value display, and can also be used for regular frequency measurement
Gate Time: 0.64s
Measuring Range: 1MHz 1.2GHz
Measurement Accuracy: +-100Hz
Working Voltage: DC 9V 12V (with power reverse polarity protection)
Working Current: Enable Backlight: 55mA

Test frequency MHz 5 1
Sensitivity mV RMS 35 20 1
Test frequency MHz 5
Sensitivity mV RMS 14 30 65 80 8 nboard Interface:
RF INPUT (measurement signal input): XH2.54-2P square socket
ICSP INPUT (MCU programming interface): XH2.54-6P pin
POWER INPUT: XH2.54-2P square socket
How to Use:
1. Please check the power supply voltage (DC 9V-12V) and polarity before use, and then turn on the power supply after confirming that it is correct. The machine has a fool-proof design, the power supply polarity is reversed, the machine will not work, but it will not produce destructive consequences.
2. The measurement signal input is connected to the test line (wired method) or antenna (induction method) with the 2P square socket.
3. Turn on the power of the instrument to warm up for a few minutes and wait for the frequency reference to stabilize before performing measurement operations.
