100% brand new and high quality
Made of high-quality materials, durable
The host is made by the United States Microchip (Microchip) PIC16F648A as a 65MHz core frequency counter.
Japan KDS frequency reference temperature compensated voltage controlled crystal oscillator (±2.5 ppm VC-TCXO)
Unique gate control and precise time algorithm (non-timer interrupt)
The door (display refresh) time is 0.64 seconds, and the frequency value is displayed in real time
Frequency measurement accuracy of 10Hz/100Hz (one digit on the right) is optional
Dual IF design, IF value and positive/negative preset mode can be used separately, of each other
The display driver adopts a dedicated LED display chip and high-brightness digital tube to reduce external interference
ARK adopts a six-digit 0.56-inch digital display, automatic blanking of the invalid zero position, and eight-digit brightness adjustable
The circuit structure is simple and reasonable, two-key control, simple operation
Settings are automatically saved, start and call directly
