Feature:

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

  • Sensitivity:（mV RMS） 14 30 65 80 80 35 175 270 310

• RF INPUT (measurement input): XH2.54-2P socket
• ICSP INPUT (MCU programming interface): XH2.54-6P pin
• POWER INPUT: XH2.54-2P socket

• 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
• The measurement input is connected to the test line (wired method) or antenna (induction method) with the 2P socket
• Turn on the power of the module to warm up for a few minutes and wait for the frequency reference to stabilize before performing measurement operations
