1602LCD RF Signal Generator 35MHz -4000MHz Time Source Signal Generator ADF4351 VFO HXY D6 V1.02 DC 4.5-5.5V

Description

1602LCD RF Signal Generator 35MHz -4000MHz Time Source Signal Generator ADF4351 VFO HXY D6 V1.02 DC 4.5 -5.5VDescriptions:This product operation keyboard has 15 ppt keys, 0~9 number keys, 10, "++" and "--" keys to adjust the frequency to use, also produces emission output behavior, short press "++" or "-- ”Key stepping adds 1khz or minus 1khz to the frequency output. Pressing “++” or “--” for more than 1 second will result in a continuous or continuous subtraction scan mode. The step is 1khz at 35mhz~138mhz; 138mhz The step is 10khz at ~550mhz and 100khz at 550mhz~4000mhz. To end the scan, simply press the ++ -- button or the "ok" button. The ok button is the output control button. Press it to launch. Press again to stop the transmission. The emission behavior caused by ++ or -- needs to press OK twice to end the transmission. This product will display >> in the upper right corner of the display when there is output emission behavior. The C key will end the transmission and the frequency will be zero. Stepping <>key, used for continuous plus continuous subtraction scan mode for easy adjustment, cycle selection step "1K", "10K", "100K", "1M", although not very useful, but also small Improvement, the V1.01 board as long as the keyboard on the hole welding a 3.3k resistor and a PPT touch button to complete the improvement (compared to the keyboard board diagram, very simple), then, buy an AVR ISP download on Taobao The line downloads the bottom layer of the new MCU, and there is a new underlying source code and .hex file in the network disk. The fuse bit C9EF is not wrong.
